The foundation of the stupa here was laid by Sanghmitra, Ashoka's daughter on her way to Sri Lanka. This site was excavated by Archaeological Survey of India in 1923. The operation unearthed several stupas, chaityas and viharas. The Mahastupa, built on wheel shaped plan 17 feet in diameter with a raised platform running all around the drum and Ayaka platforms on cardinal directions.

Adurru is famous for a mound which the localites call Dubaraju Gudi. Excavations carried out in the year 1953 brought to surface a mahastupa which measures 17 feet in diameter. A raised platform surrounds it all around. The excavations also revealed shreds of jars, troughs, dishes and bowls of red and kaolin. The excavation site covers an area of 2. 04 acres and makes for a worthwhile visit during your Buddhist trip to Andhra Pradesh

As this Buddhist centre is home to the remains of stupas, several upa-stupas, chaityas and viharas, this is considered as ‘Mahakshetram' by Buddhist monks and followers even today. In 1953, the ASI conducted excavations that brought to light the remains of stupas, chaityas and viharas. The most beautiful and the most famous one is the mahastupa, built like a giant wheel with a platform with a diameter of 17 feet. Located around it are vedika (drum) and ayaka platforms that mark the cardinal directions. In 1955, the ASI declared this a protected monument.

The excavations also brought to light artefacts such as jars, troughs, dishes and bowls. On the front side, (on the east) are two upa-stupas with the same wheel-based structure. There are also round and square structures on the west side of the main stupam — all systematically connected with each other from all the sides. The best time to visit Adurru is between the months of November and March. The excavations can be visited during timings 8:00 AM - 5:00 PM.
