The Buddhist site of Udaygiri is district Jajpur (Orissa State) on the slope of a crescent shapped low hill, is located on the right bank of Birupa river.

The largest Buddhist complex in Orissa, Udaygiri has assumed further importance after recent excavations which revealed the ancient name of the monastery as Madhavapura Mahavihara. The excavations also brought to light a sprawling complex of brick monastery with a number of Buddhist sculptures. The entire area is found located at the foothills of a large hill that acts as an imposing backdrop.

The archaeological remains at Udaygiri consist of a brick stupa, two brick monasteries (one excavated and the other still unexcavated), a beautiful stepped stone well with inscriptions on it, and rock-cut sculptures at the top of the hill behind. Chronologically, the Udaygiri Buddhist complex is later than Ratnagiri and Lalitgiri, and the monasteries probably flourished between the 7th and the 12th centuries A D.

The large number of exposed sculptures from the excavations, as well as those still in situ, belong, obviously to the Buddhist pantheon and consist of Bodhisattva figures and Dhyani Buddha figures. Interestingly, although the site is located close to Ratnagiri (about 5 km), Udaygiri does not posses a number of Vajrayana sculptures, Much is still to be known about this site. In its present state, Udaygiri provides visitors a grand sight with its newly excavated sprawling monastery complex that has to be reached through a long stairway. The unexcavated area poses a mystery to archaeologists, art lovers and lay visitors alike with the prospects of the hidden treasures that lie buried. Adventure seekers will be thrilled by the ascent to the hilltop. The hilly, serpentine, all weather approach road on the other side of Udaygiri is another added attraction.
