Looking down Bussorah Street from its outer end, you see a brick-paved pedestrian lane lined on both sides by brightly painted two-storey shophouses, and at the far end, framed squarely on the axis of view, a cream-walled building with pointed arches crowned by two large golden onion domes. Small corner towers rise at the four angles of the roof. The entire street seems laid out to draw the eye straight toward those domes.
Coming closer and looking up at the base of each dome, you notice a dark band circling the drum, which on closer inspection proves to be thousands of dark glass bottle bottoms set side by side. That band represents the contributions of poorer Muslim families when the mosque was rebuilt nearly a century ago, and it remains the detail most fondly remembered about this place. Inside, the vast prayer hall contains no statues and no paintings, only a recessed niche in the wall facing Mecca before which worshippers stand shoulder to shoulder in straight horizontal rows. The entire building sits at an angle to the surrounding street grid so that those rows face the exact direction of prayer.
IMasjid Sultan and Singapore's Muslim Community
The full Malay name is Masjid Sultan, known in English as Sultan Mosque and in Vietnamese as Thánh đường Sultan. The Arabic word masjid literally means a place of prostration where believers bow in prayer, distinct from a Buddhist temple, a Taoist shrine, or a Christian church. The word Sultan refers to Sultan Hussein Shah of Johor, who signed the 1819 treaty with Sir Stamford Raffles establishing the British trading post in Singapore and whose royal residence (Istana Kampong Glam) stood immediately beside the mosque. Built for the royal court and the surrounding Malay settlement, it functioned from the outset as Singapore's royal mosque.
The mosque stands in Kampong Glam, the district allocated to the Sultan and the Malay, Arab, and Bugis communities in the earliest colonial town plan. Today Singapore's Muslim population comprises primarily ethnic Malays alongside Indian, Arab, and other Muslim communities, the majority following the Shafi'i school of Sunni jurisprudence, the same school followed by Cham Muslims in An Giang, Vietnam, and throughout maritime Southeast Asia.
The foundation of Islam is tawhid, the absolute oneness of God, who is beyond physical form and cannot be depicted in images. Consequently, a mosque contains no statues, no figurative paintings, no altar, and no ritual food offerings, relying instead on Arabic calligraphy and geometric ornament. The Five Pillars of Islam are the declaration of faith, prayer five times daily, fasting during the month of Ramadan, charitable almsgiving (zakat), and pilgrimage to Mecca (Hajj) for those able. The prayer leader is called an imam, a role of communal leadership and scholarship rather than a sacramental priesthood.
A principal congregational mosque where the community gathers for the Friday sermon is called a masjid jami in Arabic. Sultan Mosque serves this role, and with a capacity of up to 5,000 worshippers in its main prayer hall according to official records, it is a premier gathering place during major Islamic festivals.
A common misconception: the two golden domes on the roof are not objects of veneration and house no relics inside. In Islamic architecture, a dome is simply a structural roof spanning a wide hall and a visual landmark identifying a mosque from afar. For that reason, the two domes here do not even cover the same kind of space: according to the National Heritage Board and Singapore Infopedia, the eastern dome caps the main entrance foyer facing Muscat and Bussorah Streets, whereas the western dome crowns a royal mausoleum facing North Bridge Road (where Tengku Alam, Sultan Hussein Shah's grandson who died in 1891, and other royal family members are buried). Worshippers come not to venerate the dome, but to stand in prayer rows beneath the roof.
IITwo Buildings on the Same Ground
The mosque's history spans two successive structures on the same site: the single-storey brick mosque built in 1824 for the Sultan's court, and the present twin-domed building erected from 1928 onward after the original structure grew too small for the expanding community. What remained constant across both buildings was the footprint and the direction of prayer.
- 1824Construction of the first mosqueSultan Hussein Shah initiates construction of a mosque next to his palace. Through Sir Stamford Raffles, the British East India Company contributes 3,000 Spanish dollars toward the building fund, according to Singapore's National Heritage Board.
- 1826Completion of the original buildingThe first mosque is completed in 1826 as a single-storey brick structure with a double-tiered pitched roof in the traditional Southeast Asian mosque style, as recorded by Singapore Infopedia and the National Heritage Board.
- 1879Governance by community trusteesTengku Alam (Sultan Alauddin Alam Shah, grandson of Sultan Hussein Shah) entrusts management of the mosque to a five-member committee in 1879. In 1914, the colonial government establishes a twelve-member Board of Trustees representing six Sunni Muslim community groups in Singapore.
- 1924Decision to rebuildFollowing the grant of a new 999-year lease, the Board of Trustees approves plans for a larger replacement mosque at an estimated cost of 200,000 to 250,000 Straits dollars, commissioning architect Denis Santry of Swan and Maclaren.
- 1928 to 1932Construction of the present mosqueWork begins in 1928. Singapore Infopedia records a formal opening ceremony on December 27, 1929 when the building was about two-thirds finished, while the National Heritage Board records final completion on February 26, 1932.
- 1968First major renovationRepairs and upgrading cost S$145,000, including roughly S$37,000 donated by King Faisal of Saudi Arabia, according to Singapore Infopedia.
- 1975National MonumentThe mosque is officially gazetted as a National Monument of Singapore on March 8, 1975.
- 1993Three-storey annex buildingA three-storey annex built in matching architectural style at a cost of S$4.2 million opens in July 1993 (Singapore Infopedia cites July 10, while open encyclopedia records cite July 8).
Two minor date differences between sources are worth noting side by side. Regarding the completion of the present building: Singapore Infopedia notes that the mosque was formally opened on December 27, 1929 while two-thirds complete and finished in 1932, whereas the National Heritage Board states the final completion date of February 26, 1932. The two accounts complement rather than contradict each other. Regarding the 1993 annex opening: sources cite either July 8 or July 10, 1993. The most recent major restoration took place from 2014 to early 2016 at a cost of S$3.65 million, commemorated by a plaque unveiled by Prime Minister Lee Hsien Loong on January 16, 2016.
One important social detail recorded by the National Heritage Board: the twelve-member Board of Trustees comprised two representatives each from six Muslim communities in Singapore (Malay, Bugis, Javanese, Arab, Northern Indian Hanafi, and Southern Indian Shafi'i), and construction funds were raised across the entire Muslim population rather than solely from royal patronage. The ring of glass bottle bases beneath the domes preserves the memory of that collective effort.
IIITwin Golden Domes, Minarets, and the Ring of Glass Bottle Bases
The National Heritage Board classifies the building's design as Indo-Saracenic, a late nineteenth- and early twentieth-century architectural style developed by British architects in India that combined Mughal and Moorish features (onion domes, pointed arches, minarets, and crenellated parapets) with European structural engineering. Its architect, Denis Santry of the prominent colonial firm Swan and Maclaren, was not Muslim. The building is thus an Islamic house of worship designed by a non-Muslim Irish architect according to the liturgical requirements and funding of Singapore's Muslim community.
Two large gilded ogee (onion-shaped) domes crowning the axis of the building. The eastern dome caps the main entrance foyer facing Muscat Street, while the western dome sits above the royal mausoleum along North Bridge Road (where the roadway bends around the mosque). They form the signature skyline of Kampong Glam.
Around the base (neck) of each golden dome runs a dark band formed by thousands of dark glass soya-sauce and beverage bottle bottoms stacked together. National Heritage Board records explain that poorer Muslims donated empty bottles so that even those without money could contribute tangibly to the rebuilding.
Each corner of the building features a tower with spiral stairs leading up to calling balconies topped by small gilded cupolas. Flanking the main east facade are two tall minarets rising to the height of an eight-storey building, historically used by the muezzin to chant the call to prayer (adhan) and today fitted with loudspeakers.
Set on a 4,109-square-meter site, the two-storey prayer hall measures 60 by 40 meters, supported by twelve octagonal columns with an upper gallery reserved for women, accommodating up to 5,000 worshippers. Pointed arched windows line the walls, and the carpeted floor is marked in straight rows for congregational prayer.
The semicircular niche recessed into the wall facing Mecca is the mihrab, indicating the qibla direction without housing any statue or icon. Beside the mihrab stands the mimbar, a stepped pulpit from which the imam delivers the Friday sermon (khutbah).
Opened in July 1993 and designed in matching Indo-Saracenic style, the annex houses a 550-seat multipurpose auditorium, classrooms, and community offices.
Visitors accustomed to traditional Vietnamese communal houses and Buddhist temples will notice two striking differences. First, there is no multi-tiered longitudinal hierarchy of altars: after crossing the threshold and performing ritual ablutions, everyone enters a single unified hall and stands shoulder to shoulder in horizontal rows. Second, the architectural detail most cherished by the community is not gold or marble, but humble glass bottle bottoms. In a sanctuary dedicated to a formless God, what takes visible form on the exterior is the shared participation of rich and poor alike.
IVSite Topography and Orientation
A clear preliminary note is essential. Islam does not teach or practice geomancy (phong thủy). The orientation of every mosque on earth is governed by a single, absolute rule: the qibla, the great-circle direction toward the Kaaba in Mecca. From Singapore, the qibla points west-northwest. Open encyclopedia and heritage records explicitly note that Sultan Mosque sits skewed at an angle to the rectangular street grid of Kampong Glam so that its prayer hall faces Mecca directly. No geomantic compass, birth year, or elemental trigram plays any part in that alignment.
The observations below represent purely a comparative reading through traditional Vietnamese landform concepts, offered by the library for readers familiar with that system rather than anything found in Islamic or heritage documentation.
The first feature that catches the eye is the visible skew. While Kampong Glam was laid out on a rectilinear colonial street grid, the mosque rotates to follow the qibla, so anyone standing at the street corner can see that the building does not run parallel to the neighboring shophouses. Traditional East Asian geomancy orients each building individually according to local hills, watercourses, and the patron's birth data. Islam does the exact opposite: every mosque worldwide points toward a single focal point regardless of local terrain. Viewed through traditional eyes, this is an external-center system whose reference point lies thousands of miles away, and the diagonal turn of the walls against the street grid makes the difference between the two systems immediately visible on the ground.
Regarding urban axiality, the eastern entrance of the mosque stands squarely at the end of Bussorah Street, a pedestrian mall running straight toward the facade. In domestic geomancy, a road aiming straight at a front door is called a piercing road (lộ xung) and is generally avoided for private homes. For major public and ceremonial monuments such as communal temples or palaces, however, a straight axial approach acts as a spirit way (thần đạo) that channels sightlines and foot traffic toward a central landmark. Read in that civic sense, Bussorah Street serves as an elongated bright hall (minh đường), the two rows of low two-storey shophouses act as flanking Green Dragon and White Tiger arms (long hổ), and the twin-domed facade commands the head of the axis.
Regarding terrain, Kampong Glam occupies flat alluvial coastal land near the former shoreline and the Rochor River mouth, without natural hills. Where reclamation has pushed the sea further out and modern high-rises ring the outer district, the two gilded onion domes rising above the low conservation shophouses keep the mosque visually preeminent across the quarter.
Regarding form, classical five-element shape lore associates rounded domes and golden color with Metal (Kim) and vertical corner towers with Wood (Mộc), creating a symmetrical frame around the central domes. Again, domes and minarets are centuries-old conventions of Islamic architecture that developed entirely independently of East Asian landform theory.
VDaily, Weekly, and Annual Observances
The liturgical rhythm of the mosque unfolds on three levels: the five daily prayers, the weekly congregational prayer on Friday, and annual festivals calculated by the Hijri calendar, the Islamic lunar calendar. Because the twelve-month Hijri year is roughly eleven days shorter than the solar year, Islamic festivals cycle gradually through the Gregorian seasons rather than remaining fixed to a single solar season like the East Asian lunisolar calendar. In Singapore, Hari Raya Puasa and Hari Raya Haji are national public holidays.
| Observance | Calendar Timing | Description |
|---|---|---|
| Five Daily Prayers (Salat) | Daily, determined by the sun's position | Performed at dawn (Fajr), midday (Dhuhr), afternoon (Asr), sunset (Maghrib), and night (Isha), preceded by ritual ablution with water (wudu). |
| Friday Prayer (Jumu'ah) | Weekly on Fridays at midday | The principal weekly congregational service featuring a sermon (khutbah) delivered from the mimbar followed by communal prayer, when the hall is fullest. |
| Month of Ramadan | Hijri calendar, 9th month | A month of fasting from dawn to sunset. The streets around Sultan Mosque host a lively Ramadan bazaar, and worshippers gather at the mosque to break fast (iftar) and perform nightly Tarawih prayers. |
| Hari Raya Puasa (Eid al-Fitr) | Hijri calendar, 1st of Shawwal | The festival marking the end of the Ramadan fast. Thousands gather at the mosque for special morning prayers before visiting family and neighbors. |
| Hari Raya Haji (Eid al-Adha) | Hijri calendar, 10th of Dhul Hijjah | The Festival of Sacrifice coinciding with the annual Hajj pilgrimage to Mecca, marked by morning prayers and charitable distribution of meat to those in need. |
| Maulid (Mawlid al-Nabi) | Hijri calendar, 12th of Rabi' al-Awwal | Commemorating the birth of the Prophet Muhammad, observed by Malay Muslim communities with Qur'anic recitation and religious lectures. |
Beyond prayer services, Sultan Mosque operates within the network administered by the Islamic Religious Council of Singapore (Majlis Ugama Islam Singapura, abbreviated MUIS), fulfilling the classic communal functions of a masjid: Qur'anic education, collection and distribution of charitable alms, and civic outreach. The library found no documented records of specifically Vietnamese Muslim communal activities at this mosque and therefore makes no claim on that point.

Because this is an active house of worship, visitors must observe mosque etiquette. Remove shoes before entering. Dress modestly: men in long trousers and sleeved shirts, women with arms and legs covered and a headscarf, and the mosque provides complimentary robes at the entrance for visitors who need them. Non-Muslim visitors are asked to remain in the designated visitor viewing areas rather than stepping onto the main prayer hall carpet, never to walk directly in front of someone at prayer, to speak quietly, and not to photograph worshippers during prayer. Friday midday and Ramadan evenings are the busiest times, when sightseeing visitors should wait until prayers conclude.

?Quick Questions
When was Sultan Mosque in Singapore built
The first mosque was built in 1824 next to Sultan Hussein Shah's palace and completed in 1826 as a single-storey brick building with a double-tiered pitched roof. The present twin-domed building was begun in 1928 to designs by Denis Santry of Swan and Maclaren, partially opened in December 1929, and completed on February 26, 1932. It was gazetted as a National Monument on March 8, 1975.
What is the dark ring of glass bottle bases on Sultan Mosque's domes
Around the base of each golden onion dome runs a dark band composed of thousands of glass bottle bottoms stacked together. According to Singapore's National Heritage Board, poorer Muslim families donated empty glass bottles during the rebuilding campaign so that congregants of all income levels could have a lasting share in the mosque.
Which direction does Sultan Mosque face
It faces west-northwest along the qibla toward the Kaaba in Mecca. For that reason, the mosque sits at an angle to the rectangular street grid of Kampong Glam. Islam does not practice feng shui, and this orientation is determined solely by the qibla.
Can non-Muslims visit Sultan Mosque
Yes, outside prayer times and by observing mosque rules: remove shoes, dress modestly (robes and headscarves are loaned at the entrance), stay within the designated visitor areas rather than walking onto the main prayer carpet, and refrain from photographing worshippers at prayer. Friday midday is closed to tourist visits during the congregational service.
What branch of Islam does Sultan Mosque belong to
It belongs to Sunni Islam, with the majority of Singapore's Muslim community following the Shafi'i school of jurisprudence, the same school practiced by Cham Muslims in An Giang, Vietnam, and across Malaysia and Indonesia. Administered by the Islamic Religious Council of Singapore (MUIS), it is regarded as the historic principal mosque of the nation's Muslim community.
