The ruins of Vikramshila Mahavihara sit on a hillock near Antichak village, about 50km east of Bhagalpur on the Kahalgaon road. This was one of the great Buddhist universities of medieval India, founded in the late 8th century and destroyed in the 13th — a centre of Vajrayana Buddhism that attracted students and scholars from Nepal, Tibet, and Southeast Asia.
Archaeological excavations have revealed the central stupa, monastery cells, and other structures of the complex. A small museum on site displays some of the finds: terracottas, copper plates, coins, and sculptures, including a fine collection of Pala-period Buddhas. The site itself is atmospheric — a quiet mound above the Ganges plain, the exposed brickwork suggesting the scale of what once stood here.
Getting there is straightforward by shared auto or bus from Bhagalpur's main bus stand, or by private vehicle. Allow half a day for the round trip and a proper visit to the ruins and museum. Combine it with the dolphin sanctuary at Kahalgaon, which is nearby.
