Ballal Dhipi is a historic archeological site on the eastern flood plain of the Hooghly in Nadia, West Bengal, a few kilometres east of Nabadwip. The remains date back to the 12th century AD and earlier. A 30-ft structure of solid terracotta bricks is spread over an area of 1,300 sq ft. with a floor made of lime and sand. It is named after Ballala Sena (1160-1179) of the Sena dynasty.
Archaeologists have found traces of a temple complex. Historians differ on the origin of the structure. It may be the ruin of a Buddhist stupa or vihar, possibly built between the 11th and 13th centuries. It has similarities with Vikramshila Vihar, in Bihar and Shompur Vihar, in Rajshahi, Bangladesh. It may also be a part of the capital of the Sena dynasty.
Ballal Dhipi is located at Bamunpukur, near Mayapur and Nabadwip, .

The Kolkata Circle of the Archaeological Survey of India excavated the mound, during 1982-1988, and "exposed huge brick structures and various antiquities datable to c. 10th to 12th cent. AD. The brick structure include shrines on sides and a massive construction within an enclosure." The antiquities indicate the possibility of Buddhist affiliation. The structural complex covers nearly 13,000 m<sup>2</sup>. Experts opine the "stupa(vihara) of eighth/ ninth century was perhaps a seat of learning and pilgrimage up to the end of the 11th century." It is about 25 km from Krishnanagar.
The ASI has divided the site into two parts â the mound and the remains of a fort. Both the sites are identified as an ASI listed monument.
