Architecture

Dibar Dighi

Alexander Cunningham, whose "servant" visited the site in 1879–80, noted the lake to spread about 1200 square ft. Average depth was about 12 ft. The tank currently occupies about 20 acres of land and sits atop a mound, spread over 100 acres.

Kaivarta Stambha

The tank is primarily famed for housing a semi-submerged granite pillar — locally known as ''Kaivarta Stambha'' — in its center. The apex of the pillar is crown shaped and decorated with three inflated circular rings. The pillar does not have any inscriptions. Francis Buchanon-Hamilton's survey of Bengal (1807–08) measured the net height to be 22.5 cubits (33 ft, 75 in) and the diameter to be 6.5 cubits (9 ft, 9 in). He had deemed it to be octagonal in shape. Cunningham's expedition revised the height to be approximately 30 ft — the visible portion spanned 10 ft, the submerged portion 12 ft, and the rest, underground foundation. From the logged data, he determined the pillar to be nonagonal having side-length of 12 in. each; diameter came out to be 29 in. Cunningham regretted that he did not personally visit the site, noting that such a large single-shaft stone pillar was yet to be recorded in Indian subcontinent, after

's reign. A Bangladeshi archaeologist confirmed Cunningham's approximation but changed the distribution; 12 ft was above water level, 8 ft was submerged, and 10 ft was below ground.

History

The site is yet to be accurately dated. The name of the village as 'Dibar' may be derived after the name of king Dibyak or Dibya. Local legends construct a mythological origin, wherein the lake was dug within one night by a ''

took it to be a peasant rebellion against feudal suppression. The construction might have been executed in the reign of Dibyak himself or his successors — brother Rudak, and nephew Bhim.

Preservation

In 1939, the Central Government declared Dibar Dighi to be a heritage site. Rajshahi Social Forestry Division has created an artificial forest (alongside a mini-zoo) around the tank; boating trips seem to be allowed.
