Similar vihara of Deva dynasty has been unearthed at Mainamati. The relics of Mahasthangarh where the ancient city of Pundravardhana was located suggest that a large monastery was built there. Of notable sculptures in ancient Bengal, stone figures of Buddha from Ujani in Faridpur district, Varaha avatara from Bogra (10th century) the Vishnu Stela from Comilla (11th century) and Chandi image from Dhaka district (12th century) deserve special mention. Another remarkable achievement was the terracotta art of Paharpur which drew its inspiration from the simple village life. This depicts the daily life of people with intense human interest
