Poto-Poto is a bustling, densely populated district of Brazzaville. Walking through its streets, visitors suddenly spot a vivid emerald-green roof rising high above the surrounding corrugated iron roofs, glistening in the equatorial sun like a scaled back. Approaching closer reveals the glazed tile roof of a monumental church built of warm yellowish-gray sandstone, its portals and windows shaped into steep pointed arches resembling upright spearheads.
This is the Basilica of Sainte-Anne-du-Congo in Brazzaville (Basilique Sainte-Anne-du-Congo), known locally across the city as Sainte-Anne de Poto-Poto. The Republic of the Congo is a predominantly Christian nation where the Roman Catholic Church forms the oldest and largest Christian denomination. The library selects this church as its sole representative entry for the Republic of the Congo because its builders deliberately shaped its architecture to speak the visual language of the region, and because its liturgical choir has blended Central African musical rhythms with the Roman rite continuously since 1949.
ISaint Anne, the Name of the Congo, and the Title of Basilica
Belonging to the Roman Catholic Church within the Archdiocese of Brazzaville, the building is listed by gcatholic.org as a parish church dedicated to Saint Anne (Sainte Anne). Its full French name appends the geographic qualifier du Congo, of the Congo, following the French Catholic custom of associating a patron saint with the territory under her spiritual care. Naming the church Sainte-Anne-du-Congo expressed the intention of placing the entire region, rather than a single neighborhood parish alone, under Saint Anne's patronage.
In Christian tradition, Saint Anne is the mother of the Virgin Mary and the maternal grandmother of Jesus Christ. Her name does not appear in the four canonical Gospels but comes from an early non-canonical Christian text known as the Protoevangelium of James. The Roman Catholic Church celebrates the liturgical memorial of Saint Anne alongside her husband Saint Joachim on July 26. She is widely venerated as the patron saint of mothers, grandmothers, and family life. In Catholic practice, honoring a saint means asking for her prayerful intercession before God rather than offering divine worship.
Two points are frequently misunderstood. First, many travelers assume that Sainte-Anne is the cathedral of Brazzaville because it is the largest and best-known church in the capital. It is not. According to gcatholic.org, the metropolitan cathedral of the Archdiocese of Brazzaville is Sacred Heart Cathedral (Cathédrale du Sacré-Cœur), located about 1.2 km away, whereas Sainte-Anne functions as a parish church.
Second is the title of basilica. In canon law, the title of minor basilica is granted by the Holy See to churches of special historical or liturgical importance through a dated papal brief. Although virtually every public source calls the church a basilique, gcatholic.org lists that title with a question mark, and the library has not yet found any archival record specifying the date of a papal decree, even though cath.ch (in a report dated January 14, 2010) refers to the church directly as a minor basilica without citing a decree date. This entry retains the universally used name while noting transparently that documentary proof of the papal brief remains unverified.
Sainte-Anne belongs to a pioneering generation of 20th-century churches in Africa whose designers asked a fresh architectural question: should a church on African soil reflect indigenous African building forms? Readers may compare it with the Uganda Martyrs Shrine at Namugongo, whose sanctuary evokes a traditional circular hut, and with the Basilica of the Immaculate Conception in Ouidah, which adheres closely to European models. For a major modern basilica in France itself, see the Basilica of the Sacred Heart (Sacré-Cœur) in Paris.
IIFrom the 1936 Decision to the 2011 Spire
An unusual feature of this church's history is that it was consecrated while still missing a major element: the tall spire drawn in the original blueprints had to wait more than sixty years before finally rising into the sky. The architect was Roger Erell, the professional name of Roger Lelièvre (1907 to 1986), who worked alongside Spiritan missionaries (Congrégation du Saint-Esprit) including Father Nicolas Moysan and Father Charles Lecomte, as well as structural engineers William Barnett and Grandmaître. Journaldebrazza.com highlights a memorable detail: Roger Erell was a Protestant, yet this Roman Catholic church became the masterpiece for which he is best remembered. The library focuses strictly on the milestones of its construction and restoration.
- 1936Decision to buildBishop Paul Biéchy of the Spiritan congregation decided to erect a large church in the Poto-Poto district, according to journaldebrazza.com.
- 1943Groundbreaking and foundationsThe first pickaxe stroke took place on March 13, 1943 following Roger Erell's designs, and by May 31, 1944 the massive foundations were completed using over 4,000 cubic meters of concrete and stone masonry.
- 1949ConsecrationThe church was consecrated on November 1, 1949, All Saints' Day, according to gcatholic.org. At the liturgy, the choir Les Piroguiers du Congo (The Canoeists of the Congo) sang the Messe des Piroguiers, adapted from traditional Banda chants by musicologist Éliane Barat-Pepper (score delivered on May 14, 1948), per journaldebrazza.com.
- 2009Completion of major restorationAfter suffering structural damage in the early 1990s, the church underwent a comprehensive restoration led by the architectural firm of Pierre-Antoine Gatier and completed in 2009, replacing 240,000 green glazed roof tiles secured with aluminum clips and reinforcing the steel roof frame and stone masonry.
- 2011Completion of the bell towerThe spire designed by Erell but left unbuilt in 1949 was erected between July 2010 and January 2011 and inaugurated on March 25, 2011, featuring a metal structure engineered by Giovanni Di Iorio and fabricated in Italy by Errezeta, with bells cast by the Marinelli Foundry, per journaldebrazza.com.
- 2024Eightieth anniversary celebrationOn July 28, 2024, the parish celebrated the 80th anniversary of the church (counted from the 1944 completion of the foundations), according to adiac-congo.com. During the ceremony, church leaders appealed for roof repairs to address rainwater leaks.
Published sources diverge on four points. First is the construction period. Journaldebrazza.com and acteur-fete.com give 1943 to 1949. The restoration architectural firm, pag-architecture.com, gives 1943 to 1951. The travel site travel2unlimited.com gives 1949 to 1959, which appears to be a typographical error. The library follows the March 13, 1943 groundbreaking date and the November 1, 1949 consecration date recorded by gcatholic.org, while noting that finishing work continued until 1951.
Second is the eightieth anniversary milestone. The celebration held on July 28, 2024 and reported by adiac-congo.com counted eighty years from 1944, corresponding to the year the massive foundations of over 4,000 cubic meters of concrete and masonry were completed (May 31, 1944), rather than from the first pickaxe stroke on March 13, 1943 or the consecration on November 1, 1949.
Third is the structural material: acteur-fete.com describes a concrete structure, whereas pag-architecture.com emphasizes sandstone masonry and a steel roof frame. In fact, the building combines both: the foundations, primary structural ribs, and 10-meter cantilevered gallery use reinforced concrete, while the enclosing walls are built of Djoué sandstone masonry and the roof rests on a steel truss frame. Fourth is the spire height: journaldebrazza.com gives 83 meters, whereas a pre-construction report on cath.ch projected a spire height of about 67 meters. This entry cites the 83-meter figure alongside both sources.
IIISpearhead Arches, Snake-Scale Roof Tiles, and Djoué Sandstone
The floor plan of Sainte-Anne follows the classic Latin cross layout terminating in a trefoil apse (chevet tréflé), with a long central nave intersected by a transept. According to journaldebrazza.com, the church measures 85 meters in length, 45 meters across the transept, and 22 meters in height beneath the vault. Its architectural originality lies in the profile of its arches. In place of European Gothic ribbed vaults, Erell designed smooth, steeply pitched pointed arches formed by two intersecting curves, which journaldebrazza.com explains were inspired by Congolese spearheads, overarching bamboo forest paths, and hands joined in prayer. According to pag-architecture.com, the lateral bays were intentionally left open without traditional stained-glass windows to allow natural cross-ventilation in the equatorial climate, while natural daylight enters from the roof ridge overhead through tinted glass blades.
The firm pag-architecture.com describes the building as a synthesis between a French basilica plan and the steep conical profile of traditional Logone huts. The walls are built of Djoué sandstone, quarried along the Congo River near the confluence of the Djoué River outside Brazzaville. Supported by a steel frame, the roof is covered with 240,000 green glazed tiles arranged in overlapping fish-scale rows that evoke the skin of a green mamba snake. Inside, a reinforced-concrete gallery cantilevers 10 meters into the nave without supporting columns, edged by a wrought-iron balustrade modeled on pre-colonial Central African weapons. The high altar is a monolithic block of Congo River granite measuring 5.50 meters long, 1 meter wide, and 0.25 meters thick and weighing about 3 tons, while the ironwood (bois de fer) crucifix and statues of Saint Anne, the Virgin Mary, Saint Joseph, and Saint Thérèse were carved by Congolese sculptor Benoît Konongo.
Double-curved pointed arches rising 22 meters high, inspired by Congolese spearheads and bamboo vaults, lit from the roof ridge overhead with open side bays for natural ventilation.
Glazed tiles laid in overlapping scales evoking green snake skin. All 240,000 tiles were relaid and fastened with aluminum clips during the restoration completed in 2009.
Warm yellowish-gray local sandstone masonry paired with reinforced-concrete ribs and a column-free 10-meter cantilevered tribune with a wrought-iron balustrade.
Erected from July 2010 to January 2011 and inaugurated on March 25, 2011, with an Italian-fabricated metal frame and bells from the Marinelli Foundry.
A 3-ton monolithic Congo River granite altar (5.50 x 1 x 0.25 meters) accompanied by ironwood statues carved by Congolese master Benoît Konongo.
Founded in 1949, celebrated for performing the Messe des Piroguiers transcribed from traditional Banda melodies by Éliane Barat-Pepper.

IVLandform and Orientation
This section provides a supplementary comparative reading by the library and should be understood in context. The Roman Catholic Church does not teach geomancy (feng shui), nor did architect Roger Erell design the church according to East Asian siting rules. Catholic church design follows liturgical orientation, historically favoring an east-facing apse, though 20th-century urban churches frequently align with city boulevards. According to geographic maps and OpenStreetMap data (coordinates 4.2685 degrees South, 15.2845 degrees East), the main facade and spire of Sainte-Anne face south-southwest toward the Patte d'Oie roundabout and the Congo River (Pool Malebo), while its trefoil apse points north-northeast into the Poto-Poto grid. What Erell consciously engaged with, according to architectural sources, were the equatorial climate and visual motifs of the Congo: spearheads, bamboo vaults, snake scales, and river stone. The observations below read the site through traditional Vietnamese landform principles purely as a comparative reference for interested readers.
The first feature is the great river. Brazzaville stands on the right bank of the Congo River right where the channel widens into the broad basin of Pool Malebo before plunging into the Livingstone Falls rapids. Traditional Vietnamese geomancy calls such a wide, slow-moving expanse of water a water gathering (Water Gathering (Shui Ju)) and regards land bordering a calm basin as a site that retains vital energy. While the historical reason for founding cities at such points is river navigation and portage, traditional site readers interpret it as water coming to rest.
The second feature is flat terrain and the urban axis. Poto-Poto occupies a flat, low-lying plain northeast of downtown Brazzaville without natural hills to serve as a backing mountain. In flatland geomancy, the classic adage holds that an inch of elevation acts as a mountain and an inch of depression acts as water, meaning a monumental building must establish its own vertical anchor and front court. Here the massive sandstone church and soaring green roof form the high anchor for the entire neighborhood, while the south-southwest facade opens onto the broad avenue approaching from the Patte d'Oie roundabout like an urban forecourt (Bright Hall (Ming Tang)).
The third feature is form and color. Traditional East Asian five-phase (Five Elements (Wu Xing)) reading associates pointed shapes with Fire, tall rising forms and green color with Wood, and ochre-yellow stone with Earth. With its pointed arches, emerald-green roof, and yellowish sandstone walls, the building happens to follow the generative cycle in which Wood feeds Fire and Fire produces Earth. That correspondence is an engaging parallel for readers familiar with five-phase symbolism, even though Erell chose green for snake scales and pointed arches for spearheads.
The fourth feature is zenithal light and cross-breezes. The nave draws daylight from the roof ridge overhead while admitting cooling breezes through open lateral bays. Traditional Vietnamese architecture calls a central overhead light well a sky well (thiên tỉnh) where celestial energy descends, whereas in Christian symbolism light from above evokes divine grace. Starting from entirely different origins, both traditions direct the viewer's gaze upward toward the crown of the space.
VThe Feast of Saint Anne and the Liturgical Year in Poto-Poto
