Sathmahal Prasada in Sri Lanka is a seven storied pyramid situated on the high ground between the ancient city of Polonnaruwa. The structure has access to all four sides and an extra staircase to reach the highest levels. It is believed to have been built between the 11th and 13th centuries. However, there is no record of this pyramid, its builder or purpose. Its height is 9 meters and its height is 30 feet (9 meters).
The Seven Mansion is believed to be a stupa because of its proximity to Buddhist ruins such as stupas and monasteries. However, some argue that this structure is very similar to the stupas of Siam and Cambodia. It is believed that the stupa was built by the Cambodian soldiers who served the King of ancient Sri Lanka as a tribute to Cambodia and as a place of pilgrimage. However, the architecture is completely different and different from any other ancient architecture in Sri Lanka. It is the only stepped pyramid in Sri Lanka and is one of the four ancient buildings with rectangular bases. All these have damaged stupas or monasteries in Anuradhapura. The other three buildings do not show signs of being pyramids, and they all appear to be structured.
The Archaeological Department has made available this site to the public within a few months.
