Somapura Mahavihara: The Great Monastery of Paharpur

On a flat green plain in Naogaon District, in the north-west of Bangladesh, a great square of ruined brick walls surrounds a terraced brick mountain. This is Somapura Mahavihara, the "Great Monastery of Somapura", known today by the name of the village beside it: Paharpur. Founded under the Pala kings more than twelve centuries ago, it was one of the great Buddhist monasteries of Asia — a walled monastery-city of 177 monks' cells arranged around a monumental cruciform shrine, a centre of scholarship linked to Nalanda and Bodh Gaya, and, in the judgement of UNESCO, the most spectacular and important pre-Islamic monument in Bangladesh. Its ruins, excavated in the 1920s and 1930s, were inscribed on the World Heritage List in 1985, and the plan invented here went on to shape Buddhist architecture from Myanmar to Java.

A Monastery-City in Ancient Varendra

Paharpur lies in Badalgachhi Upazila, about 35 kilometres north of Naogaon town, in the region the early medieval world knew as Varendra — the fertile but distinctively dry-fringed tract between the Ganges and the Brahmaputra systems. Even in ruin, the scale is striking. The monastery proper covers some 11 hectares (27 acres), and UNESCO describes it as the second largest single Buddhist monastery south of the Himalayas. The village name Paharpur, "hill village", comes from the ruin itself: for centuries the buried central temple stood as a lone hillock in the flat alluvial plain, a landmark long before anyone knew what it was.

Somapura belonged to a small family of great Pala-era monasteries — the mahaviharas — that functioned as the universities of the Buddhist world. Nalanda and Vikramashila in modern Bihar are the famous names; Somapura was their Bengali counterpart, and epigraphic evidence shows the three were in close contact. Scholars, texts and reputations circulated between them, and the Vajrayana form of Mahayana Buddhism that flourished in the Pala realm was practised and taught within these walls.

Foundation Under the Pala Kings

The monastery's founder is named by the most eloquent piece of evidence the excavators found: a clay seal, recovered from the compound, inscribed in Sanskrit "Shri-Somapure-Shri-Dharmapaladeva-Mahavihariyarya-bhikshu-sangghasya" — the seal of the community of venerable monks of King Dharmapala's Mahavihara at Somapura. On that basis the foundation is credited to Dharmapala, the second and greatest of the early Pala kings, who ruled in the late eighth and early ninth centuries (UNESCO dates him 770–810; other chronologies give about 781–821).

The record is not entirely tidy, and an honest account should say so. Tibetan historical works — among them the Tibetan translations of the Dharmakayavidhi and the Madhyamaka Ratnapradipa, Taranatha's history and the Pag Sam Jon Zang — credit the building instead to Dharmapala's successor Devapala (c. 810–850), after his conquest of Varendra. What is certain is that the royal connection continued: a pillar inscription of Mahendrapala's reign (c. 850–854) names a monk of the monastery, Bhikshu Ajayagarbha, and Taranatha records that the monastery was repaired under Mahipala (c. 995–1043), two centuries after its founding — the mark of an institution still worth a king's money.

Nor was the sacred geography new. In 1927 excavators found, in the monastery's north-east corner, a copperplate dated to 479 AD recording a donation by a Brahmin couple to Guhanandi, a Jain acharya of the Pancha-stupa Nikaya, at a nearby settlement. A Jain vihara evidently stood in the neighbourhood three centuries before Dharmapala, and the Buddhist great monastery rose in a landscape that was already holy.

The Plan: 177 Cells Around a Cruciform Shrine

The layout of Somapura is its genius, and it can still be read at a glance from the top of the central mound. The monastery is a vast square, about 920 feet — roughly 275 metres — on each side. Its outer walls are not walls at all in the usual sense: they are formed by continuous rows of monks' cells, opening inward through a veranda onto the courtyard. In the monastery's final building phase the cells numbered 177. The main entrance, an elaborate fortified gateway, pierced the northern side; the kitchen, refectory and other service buildings clustered in the south-east corner.

At the centre of the courtyard stands the main shrine, and it is unlike anything built before it in Asia. Its ground plan is cruciform — a cross elaborated with projections at every re-entrant angle — and the same cross-shaped plan repeats at each level as the building rises in three broad terraces to a height of about 70 feet, crowned originally by a massive central block. Around the intermediate terrace runs a wide circumambulatory path, the pradakshinapatha, along which pilgrims walked clockwise past four chapels set at the cardinal points. At ground level a second circumambulatory path, 15 feet wide, follows the same elaborated cruciform outline.

Decoration was lavished where the pilgrim's eye would fall. Two bands of terracotta plaques once ran around the full perimeter of the shrine at the intermediate level — about half survive in place — showing gods and goddesses, warriors, lovers, musicians, animals and scenes of everyday Bengali life. At the base of the shrine stand more than 60 stone sculptures, most of them, strikingly, of Hindu divinities: Krishna, Balarama, Shiva and others, carved and installed on a Buddhist monument without embarrassment. The excavator K. N. Dikshit distinguished three building periods in the cells and four in the central temple, so the complex a visitor sees is the product of centuries of rebuilding, not a single campaign. A short walk east of the enclosure, the smaller mound of Satyapir Bhita holds the remains of a Tara temple ringed by votive stupas — a satellite shrine of the great monastery.

A Centre of Learning: Atisa and the Scholars

For roughly three centuries Somapura was a working university. UNESCO notes that many Buddhist treatises were completed at Paharpur, and that its religious life was closely linked with Bodh Gaya and Nalanda. The names that survive in the Tibetan records give the place a human scale: Ratnakarashanti, one of the great logicians of the age, served as a sthavira — an elder — of the vihara; the master Bodhibhadra lived here as a resident monk; other named scholars, Kalamahapada, Viryendra and Karunashrimitra among them, spent part of their lives within these walls.

Above all, tradition attaches to Somapura the most famous Bengali Buddhist of the millennium: Atisa Dipankara (982–1054), the master whose mission to Tibet in the 1040s reshaped Tibetan Buddhism. Tibetan and later accounts place Atisa at Somapura as its abbot for a period given as fifteen years, and say that he composed his Madhyamaka Ratnapradipa — the "Lamp of the Middle Way" — during his stay. This needs careful handling: Atisa's best-documented posts were at Vikramashila and Odantapuri in Bihar, and the Somapura chapter rests on tradition rather than on contemporary inscriptions. But it is an old and persistent tradition, his preceptor Ratnakarashanti's residence here is independently recorded, and it is entirely plausible that the leading scholar of Pala Bengal taught at Bengal's leading monastery. What is not in doubt is the world Somapura belonged to: a network of great monasteries in which a monk of Atisa's generation could study, teach and write.

Decline and Abandonment

The monastery's last centuries were troubled. In the eleventh century Varendra was shaken by the Kaivarta revolt, in which the Kaivarta king Divya seized the region from the Palas. Into that turmoil came Jatvarma of the Varman dynasty, campaigning against Divya and hostile to Buddhism; his army attacked the monastery and set fire to part of it. The Kaivarta regime survived, and so, evidently, did Somapura — the fire was a wound, not the end — but royal patronage was becoming less reliable, and the institution never fully recovered its earlier standing.

The end, when it came in the second half of the twelfth century under the Sena dynasty, was quiet rather than violent. The ruins show no clear signs of large-scale destruction. Scholars conclude that decline came through abandonment: patronage withdrawn, monks dispersing, population displaced amid the unrest that accompanied the Muslim invasions of Bengal. Roof timbers rotted, monsoon rain ate the brickwork, jungle took the courtyard, and the great monastery subsided into the plain — remembered only as a hill, and a happy hunting ground for treasure seekers, until the archaeologists arrived.

Excavation: From Treasure Hunters to Dikshit

The modern rediscovery of Somapura began with the surveyor Buchanan Hamilton, who noticed the mound in the course of his survey of eastern India between 1807 and 1812. Alexander Cunningham, the founding figure of Indian archaeology, visited in 1879, and in 1919 the site was declared protected under the Ancient Monuments Preservation Act. Protection on paper did not at once produce knowledge; for that, Paharpur needed money and organisation, both of which arrived in 1923.

Systematic excavation began in February–March 1923 as a joint enterprise of the Archaeological Survey of India, the Varendra Research Society of Rajshahi and the University of Calcutta, financed by Kumar Sarat Kumar Ray of Dighapatia and directed in its first season by D. R. Bhandarkar, who cleared a few cells at the south-west corner. In 1925–26 R. D. Banerjee attacked the northern face of the central mound and revealed the temple's general plan and scheme of decoration. Then, from the 1926–27 season until 1933–34 — with two seasons under G. C. Chandra — the work ran under Rao Bahadur K. N. Dikshit, one of the great field archaeologists of the Survey. Dikshit's teams exposed the entire monastery, cell by cell, together with the Satyapir Bhita mound to the east, and his report, Excavations at Paharpur, Bengal, published in 1938 as Memoir No. 55 of the Archaeological Survey of India, remains the foundation of everything written about the site since. The clay seal naming Dharmapala came from these campaigns: excavation did not merely uncover the monastery, it gave it back its name.

Work has continued in shorter campaigns ever since — limited digging on the eastern wing in the Pakistan period, two phases by Bangladesh's Department of Archaeology between 1981 and 1991 aimed at testing Dikshit's building periods (the later excavations found one more), and a small excavation in the temple area in 2007–08. The site the visitor walks today is substantially the site Dikshit revealed.

The Paharpur Museum

Because no site museum was built during the British period, the finds of the 1930s were scattered: most of the sculptures from the central temple — 63 stone images once fixed to its basement — went to the Indian Museum and the Ashutosh Museum in Kolkata, a handful to the Varendra Research Museum in Rajshahi, and others later to the Bangladesh National Museum in Dhaka. Only in 1957 did the Department of Archaeology open a one-room site museum at Paharpur itself.

The present museum stands a short walk from the ruins, its own plan cruciform in deliberate echo of the central temple. Built in the 1990s with UNESCO support and renovated in 2016, it displays the site's portable heritage across four galleries: hundreds of the terracotta plaques that once sheathed the shrine, ornamental carved bricks, stone statues of Buddhist and Hindu deities — among them a fragmented Hevajra in embrace with his consort, one of the finest pieces — ceramics, terracotta utensils, seals and a bronze bust of the Buddha, spanning the pre-Pala, Pala and early Islamic periods. The museum is the essential companion to the ruins: the walls outside tell the monastery's plan, but the objects inside tell its life.

UNESCO World Heritage and a Plan That Travelled

In 1985 the ruins were inscribed on UNESCO's World Heritage List as the "Ruins of the Buddhist Vihara at Paharpur", under criteria (i), (ii) and (vi). The citation calls the monastery-city "a unique artistic achievement" whose "simple, harmonious lines and its profusion of carved decoration, in stone and terracotta, are important artistic masterpieces", and recognises the site as evidence of the rise of Mahayana Buddhism in Bengal under Pala patronage.

The most far-reaching claim is under criterion (ii). The architectural form introduced at Paharpur on a grand scale "for the first time in Asia" — the cruciform shrine at the heart of a walled monastic quadrangle — "profoundly influenced the subsequent construction of temples of Pagan in Myanmar and Loro-Jongrang and Chandi Sewer [Candi Sewu] temples in central Java. It also continued to influence Buddhist architecture as far away as Cambodia." A monastery in the Varendra plain, that is, stands in the ancestry of some of the most famous temple landscapes of Southeast Asia. UNESCO also notes the threats that come with a brick monument in a delta: salinity rising through the soil, vegetation rooting in the walls, and terracotta plaques deteriorating where they remain exposed — or being removed for safekeeping, which is why so much of the decoration is now seen in the museum rather than on the shrine.

Somapura Mahavihara Today

The site is managed by Bangladesh's Department of Archaeology, protected under the Antiquities Act, and kept as a landscaped archaeological park: lawns and paths within the ancient quadrangle, the central shrine rising over all, and the museum nearby. It is far from a forgotten ruin. Reporting in September 2025, the national news agency BSS described thousands of visitors arriving daily, domestic and foreign, and gate income of more than one crore taka a year for the government; the museum's custodian spoke of further development plans in progress. For travellers, Paharpur combines naturally with the wider heritage of the dry north-west — the old Varendra country of the Barind Tract — and with the museums and silk-and-mango city of Rajshahi, a few hours to the south.

What survives at Paharpur is, in the end, an argument in brick: that Bengal in the Pala age was not a periphery of the Buddhist world but one of its centres of production — of texts, of teachers, and of an architectural idea that travelled a thousand miles. The 177 empty cells and the eroded cross-shaped shrine make that argument more eloquently than the court's inscriptions ever did.
