Puspagiri University was a prominent Buddhist seat of learning that flourished until the 11th century in India. Today, its ruins lie atop the Langudi hills, low hills about 90 km from the Mahanadi delta, in the districts of Jajpur and Cuttack in Orissa. The actual university campus, spread across three hilltops, contained several stupas, monasteries, temples, and sculptures in the architectural style of the Gupta period. The Kelua river, a tributary of the Brahmani river of Orissa flows to the north east of Langudi hills, and must have provided a picturesque background for the university. The entire university is distributed across three campuses on top of the three adjoining hills, Lalitgiri, Ratnagiri, and Udayagiri.
