Along the overland journey southward from the ancient capital of Kharkhorin and Erdene Zuu Monastery toward the flaming cliffs and singing sand dunes of the southern Gobi, travelers cross the arid semi-desert steppe of Dundgovi Province (the Central Gobi) until a sudden ribbon of green willow and grass appears inside the rocky canyon of Saikhan-Ovoo District. Here, where the Ongi River (Ongiin Gol, flowing down from the Khangai Mountains) makes a graceful bend between craggy slate hills, dozens of weathered adobe walls and terraced stone foundations climb the steep slopes around a bright white-and-gold sanctuary: this is Ongi Monastery (Ongiin Khiid).
Built as a pair of twin monastic complexes facing one another across the northern and southern banks of the Ongi River in 1660 and 1760, Ongiin Khiid once stood as one of the largest and most prestigious Gelugpa Buddhist universities in southern Mongolia, housing nearly thirty temples and more than a thousand monks. Completely leveled by artillery and dynamite during the tragic purges of 1939, the site lay in silent ruin for over half a century until the 1990s, when a handful of octogenarian monks who had been young novices here before 1939 returned to the riverside rubble to rebuild the first active prayer hall and rekindle the Dharma lamp in the Central Gobi.
IThe Twin Sanctuaries of Khutagt Khiid and Barlim Khiid and the Four Scholastic Colleges by the Ongi River
The name Ongiin Khiid (Monastery of the Ongi River) refers to a unified monastic landscape spread across both sides of the Ongi River in the Saikhan-Ovoo hills. Historically and liturgically, the complex consisted of two twin monasteries operating in concert: on the southern bank stood the older Khutagt Khiid (Monastery of the Saintly Incarnation, founded in 1660), which encompassed eleven administrative and devotional temples; directly across the water on the steeper, sun-warmed northern hillside rose the larger Barlim Khiid (founded in 1760 by the revered Gelugpa lama Barlim Khutagt), comprising seventeen tiered temples and four specialized academic colleges.
Within the sanctuaries of Ongi Monastery, devotion followed the orthodox Gelugpa (Yellow Hat) tradition of Khalkha Mongolia: the main altars enshrined Shakyamuni Buddha, the Gelug founder Je Tsongkhapa and his two chief disciples, the Future Buddha Maitreya (Maidar), the Medicine Buddha Bhaisajyaguru (Manla), and the tantric deity Kalachakra. Inside the reconstructed main temple on the northern bank, known as Gundamba Ling, the altar today honors Shakyamuni Buddha alongside a venerated statue of Barlim Khutagt and original ritual objects that local herding families secretly buried in the earth to save them from destruction in 1939.
At its zenith in the nineteenth and early twentieth centuries, Ongiin Khiid was not merely a place of prayer for Gobi nomads, but a major four-faculty Buddhist university rivaling northern seats such as Gandantegchinlen Monastery and Shankh Monastery.
The four academic colleges (Four Datsans) that flourished inside Barlim Khiid embodied the comprehensive educational vision of Gelugpa monasticism on the steppe: first, the Philosophy College (Tsanid Datsan), where monks trained rigorously in Buddhist logic, epistemology, and courtyard debate; second, the Tantric College (Jüd Datsan), dedicated to esoteric mandala ritual and Vajrayana yoga; third, the Medical College (Manba Datsan), where physician-lamas studied desert herbs, minerals, and pulse diagnosis to heal nomadic communities; and fourth, the Astrology and Mathematics College (Zurkhai Datsan), which calculated the lunar calendar, seasonal shifts, and eclipses essential for pastoral survival in the harsh Gobi climate.
By uniting transcendent liberation with practical healing and astronomical knowledge, Ongi Monastery served for nearly three centuries as both the spiritual anchor and the intellectual heart of the Central Gobi.
Historical records of Dundgovi Province recount that the southern complex, Khutagt Khiid, was established in 1660 during the seventeenth-century flowering of Khalkha Buddhism. Exactly one hundred years later, in 1760, the eminent incarnate lama Barlim Khutagt and noble patrons of the Tusheet Khan aimag initiated construction of the grander northern complex, Barlim Khiid, terracing its seventeen temples and four colleges up the rocky amphitheater overlooking the river.
By the early twentieth century, the combined twin monasteries of Ongiin Khiid encompassed 28 to 30 temple halls built of sun-dried adobe brick, local slate, and timber hauled down from the Khangai forests, supporting a permanent community of more than 1,000 resident monks.
Visitors gazing across the vast hillside of weathered mud-brick walls at Ongi Monastery sometimes mistake them for medieval ruins abandoned many centuries ago. In reality, all twenty-eight temples of Ongiin Khiid stood intact, painted, and echoing with daily chanting right up until 1939; the dramatic ruins visible today are the direct scars of twentieth-century political destruction, standing side by side with a living twenty-first-century revival.
IIThe Tragedy of 1939 by the Ongi River and the Return of the Surviving Novices
Among all the monastic centers of Mongolia, Ongi Monastery suffered one of the most devastating blows during the anti-religious purges of the late 1930s. In 1939, armed troops arrived in the Saikhan-Ovoo canyon to liquidate the largest Buddhist university of the Central Gobi. More than 200 senior lamas and scholars were executed, hundreds of younger monks were imprisoned in labor camps or forcibly conscripted into the army, and all twenty-eight temples and four colleges on both banks of the Ongi River were systematically dynamited, burned, and reduced to rubble.
For more than fifty years from 1939 to 1990, the ruins beside the Ongi River lay deserted. Yet as soon as democratic reforms restored religious freedom in 1990, a deeply moving chapter of renewal began: three elderly monks in their seventies and eighties, who had been eleven- and twelve-year-old novice monks at Ongiin Khiid before being driven out in 1939, returned to the river valley. Pitching a single felt ger tent amid the collapsed mud-brick walls of their childhood monastery, they gathered sacred statues and ritual items that local families had hidden underground for half a century, took in young disciples, and raised funds brick by brick until the first reconstructed main temple, Gundamba Ling, was consecrated in 2004.

- 1760 to the 19th centuryBarlim Khutagt builds the northern Barlim Khiid complex and four academic collegesIn 1760 Barlim Khutagt constructs 17 temples and 4 scholastic datsans (Philosophy, Tantra, Medicine, and Astrology) on the northern hillside, expanding Ongiin Khiid to 28 temples and over 1,000 monks.
- 1939Complete demolition of the 28 temples and martyrdom of over 200 senior monksAt the height of the 1939 purges, military forces dynamite and burn both monastic complexes on the Ongi River and execute over 200 senior lamas, turning the university into ruins.
- 1990sSurviving elder monks who were pre-1939 novices return to pitch a shrine gerFollowing Mongolia's 1990 democratic transition, surviving aged monks return to the ruins, establish a ger chapel, and recover sacred artifacts hidden by local herders for fifty years.
- 2004 to the presentConsecration of the rebuilt Gundamba Ling Temple, Ger Museum, and Memorial StupaIn 2004 the reconstructed Gundamba Ling prayer hall opens on the original northern foundation alongside an archaeological museum and a white stupa inscribed with the names of the 1939 martyred monks.

Immediately beside the reconstructed Gundamba Ling temple stands a gleaming white memorial stupa housing stone plaques inscribed with the names of the more than two hundred monks executed at Ongiin Khiid in 1939. In the early 2000s, when unregulated placer gold mining in the upper reaches of the river basin threatened to dry up the Ongi River, the monks of Ongi Monastery joined hands with local herders and the Ongi River Movement to campaign successfully for the protection of the watershed, ensuring that the life-giving stream continues to flow past the monastery walls today.
IIITerraced Adobe Ruins on the Canyon Slope, the Rebuilt Gundamba Ling Hall, and the Archaeological Ger Museum
Unlike steppe monasteries built on flat plains, the architecture of Ongi Monastery (especially northern Barlim Khiid) was terraced directly up the steep rocky amphitheater of the canyon wall, evoking the cliffside monastic towns of Tibet. Looking across from the southern bank of the Ongi River, visitors behold a vast labyrinth of sun-dried mud-brick (adobe) walls and dressed stone foundations rising tier upon tier from the riverbank up the dark slate hillside.
Standing out vividly against the earth-toned ruins is the reconstructed Gundamba Ling Temple completed in 2004, with its crisp whitewashed walls and two-tiered curved roof painted in vermilion and gold. The juxtaposition of this living, incense-filled sanctuary surrounded by the untouched mud-brick ruins of twenty-seven lost temples creates one of the most poignant architectural landscapes in Inner Asia.
Dozens of thick sun-dried mud-brick walls and stone terraces stretching across both the northern and southern slopes of the Ongi River canyon, preserving the footprint of 28 historic temples and 4 colleges.
Erected directly atop the stone foundation of a former northern temple, this two-story sanctuary enshrines statues of Shakyamuni Buddha, Je Tsongkhapa, and Barlim Khutagt where resident monks chant daily.

IVThe Lie of the Land
Amid the dry, wind-swept expanses of the Central Gobi, the siting of Ongi Monastery inside the rocky canyon of Saikhan-Ovoo is a textbook illustration of the classical geomantic principle of encircling mountains and embracing water. Below is a comparative reading of the monastery's terrain and orientation through the library's traditional landform framework.
Examining the canyon mountain ring and Jade-Belt River curve at coordinates 45.3319 degrees north, 104.0086 degrees east, the Ongi River (Ongiin Gol) flows southward from the Khangai Mountains across the arid plains before entering a sheltered gorge framed by slate and sedimentary hills rising to 1,300 to 1,400 meters in Saikhan-Ovoo District. Right at the monastery site, the river makes a gentle, protective bend from west to east, forming what classical geomancy calls a Jade-Belt Watercourse (Ngoc Dai Thuy). The larger northern complex, Barlim Khiid, rests squarely within the inner concave embrace of the river bend (the auspicious side where water gathers qi rather than cutting away), while the steep rocky ridge rising immediately behind it to the north and northwest serves as a powerful Black Tortoise backing wall that blocks icy winter winds and desert dust storms.
In terms of axial orientation, the seventeen terraced temple foundations on the northern slope as well as the rebuilt Gundamba Ling Temple are aligned sitting north against the mountain slope and facing south (slightly southeast) toward the sunlit Ongi River and the lower hills of southern Khutagt Khiid, which act as a balanced Front Table Mountain (Tien An). Sheltered by sun-warmed rock walls behind and nourished by living water in front, this canyon bend forms a natural oasis of vitality in the heart of the Central Gobi.
VMemorial Rites for the Martyred Monks, River Blessing Ceremonies, and Steppe Feast Days
Inside the reconstructed Gundamba Ling temple, resident monks maintain daily liturgical chanting and preside over the annual Gelugpa Buddhist feast days for herding families across Saikhan-Ovoo District. The table below summarizes the principal ceremonies observed at Ongi Monastery.
| Date | Calendar system | Observance | Liturgical rites and community activities at Ongi Monastery |
|---|---|---|---|
| 1st to 15th day of the 1st lunar month | Mongolian Lunar Calendar | Tsagaan Sar (White Month New Year) Spring Prayer Assembly | Nomadic families along the Ongi River basin gather at Gundamba Ling Temple to offer butter lamps and silk khadags, praying for abundant summer pastures and the health of their herds. |
| 15th day of the first summer month | Mongolian Lunar Calendar | Ikh Düchen (Saga Dawa / Triple Blessed Buddha Day) | Commemorating the birth, enlightenment, and parinirvana of Shakyamuni Buddha with sutra chanting and clockwise circumambulation around the main temple, memorial stupa, and hillside ruins. |
| Midsummer (6th or 7th lunar month) | Mongolian Lunar Calendar | Hilltop Ovoo Veneration and Ongi River Protection Prayer | Monks and local herders ascend to the hilltop Ovoo above the northern ruins to offer mare's milk and chant prayers honoring the mountain and water spirits that sustain the Ongi River. |
| 7th lunar month & September 10 (National Memorial Day) | Mongolian Calendar | Memorial Service for the Over 200 Martyred Monks of 1939 | Lighting butter lamps and chanting merit-dedication prayers at the White Memorial Stupa in remembrance of the senior lamas who perished during the 1939 destruction of Ongiin Khiid. |
| 25th day of the 10th lunar month | Mongolian Lunar Calendar | Zulyn Khural (Festival of a Thousand Butter Lamps / Je Tsongkhapa Day) | Evening butter-lamp illumination inside Gundamba Ling overlooking the winter river, honoring the parinirvana of Gelug founder Je Tsongkhapa. |
Golden sunset over the adobe walls beside the desert stream. The most unforgettable hour at Ongi Monastery arrives at late afternoon, when the low Gobi sun bathes the broken mud-brick walls of Barlim Khiid in a warm terracotta glow and turns the winding Ongi River below into a ribbon of gold. Walking quietly along the dirt paths between the ruined foundations of the ancient medical and philosophical colleges while the evening bell rings from Gundamba Ling, visitors experience both the poignant impermanence of history and the quiet resilience of faith.
From its twin foundations in 1660 and 1760 through the tragedy of 1939 to its rebirth in 2004, Ongi Monastery stands by the waters of the Ongi River as an enduring monument to memory and devotion in the Central Gobi.

?Quick Questions
Which two twin monasteries made up Ongi Monastery (Ongiin Khiid), and when were they founded?
Ongi Monastery consisted of two monastic complexes facing each other across the Ongi River: the southern complex, Khutagt Khiid, was founded in 1660, while the larger northern hillside complex, Barlim Khiid, was founded a century later in 1760 by the Gelugpa incarnate lama Barlim Khutagt.
How large was Ongi Monastery at its peak before 1939?
Prior to 1939, Ongiin Khiid was one of the largest Buddhist monastic universities in southern Mongolia, encompassing 28 to 30 temple halls across both riverbanks, four specialized scholastic colleges (Philosophy, Tantra, Medicine, and Astrology/Mathematics), and more than 1,000 resident monks.
What happened to Ongi Monastery in 1939, and how was it revived after 1990?
During the anti-religious purges of 1939, military forces completely demolished all 28 temples of Ongi Monastery and executed more than 200 senior monks. After Mongolia's democratic transition in 1990, surviving elderly monks who had been young novices at the monastery before 1939 returned to the ruins, pitched a prayer ger, and raised funds to rebuild the main Gundamba Ling temple, which was consecrated in 2004.
What can visitors see at Ongi Monastery today?
Visitors can walk along trails through the expansive hillside mud-brick ruins of Barlim Khiid and Khutagt Khiid, visit the active Gundamba Ling prayer hall completed in 2004, circumambulate the White Memorial Stupa inscribed with the names of the 200+ martyred monks, view excavated artifacts in the ger museum, and climb to the hilltop Ovoo overlooking the Ongi River.
Why is the Ongi River so important to the monastery and the surrounding Central Gobi?
Flowing more than 400 km southward from the Khangai Mountains into the arid steppe, the Ongi River sustains pastoral life and creates a sheltered green canyon oasis at Saikhan-Ovoo; in the early 2000s, the monks and local herders successfully campaigned to protect the river from upstream mining so its waters continue to flow past the monastery.
