Jagjivanpur or Jagajjibanpur is an archaeological site in Habibpur block of Malda district in West Bengal state in eastern India. This site is located at a distance of 41 km east from English Bazar town. The most significant findings from this site include a copper-plate inscription of Pala emperor Mahendrapaladeva and the structural remains of a 9th-century Buddhist Vihara: Nandadirghika-Udranga Mahavihara.
The importance of this site was first indicated by the chance discovery of a copper plate inscription of the Pala emperor Mahendrapala on 13 March 1987 who was not known from any other sources till the date of this discovery. Later, the excavation by a team of the Directorate of Archaeology & Museums, West Bengal Government led by Sudhin De began in 1992 at Tulabhita mound, followed by an extensive excavation at the same site in 1995-96 under the direction of Amal Ray of the same directorate. The excavations resulted in discovery of a part of the brick built Vihara, stupas, cells with corbelled niches, verandah and a large number of antiquities, which include terracotta plaques, terracotta seals & sealings, an inscribed potsherd, beads and other objects for daily use.
The site comprises a number of mounds, most impressive of them is the 5 m high Tulabhita or Salaidanga. other significant mounds are: Akhridanga, Nimdanga, Rajar Mayer Dhipi and Nandagarh. Another significant feature of the site is a large tank, Nandadighi (Nandadirghika of Maehndrapala's inscription) which still covers a large area. Tulabhita mound covers an area of 9432 m². Total 262 trenches ( 6 m x 6 m) were laid, of which 78 trenches have been excavated so far.
The excavation has revealed six distinct layers of deposit, of which second to fourth are the most significant in terms of activities. Two phases of construction work can be identified. The first phase was probably abandoned due to the flood, the second period of construction started over it without any substantial chronological gap.
The excavation at the central part of the Tulabhita mound has revealed the eastern part of a burnt brick-built Vihara. A number of sizes of bricks (32 cm x 18 cm x 6 cm, 28 cm x 26 cm x 5 cm, 23 cm x 17 cm x 8 cm, 28 cm x 15 cm x 6 cm and 17 cm x 6 cm x 6 cm) and mud morter were used to construct the 1 m wide wall of the Vihara. The northeast and the southwest corners of the Vihara have been exposed. The exposed 1.7 m wide inner courtyard of the Vihara is made of rammed bricks with a tiled pathway. The post-holes have been traced along the pathway at a regular distance of 2.5 m. It probably indicates the existence of a shed over the pathway for circumambulation during the rainy season. A 3 m wide staircase with three steps at the eastern part of the courtyard attached to the verandah has been exposed. A brick stupa, having a circumference of 6 m and diameter of 2.25 m has also been identified. A part of the eastern verandah with rammed-floor of the Vihara has also been found.
