Initially, King Devanampiyatissa built this building for Buddhist monks to hold meetings. Later, King Dutugemunu built this building with 1000 rooms for rest. The small building now on display was constructed by King Parakiramabahu I. Not only Buddhists but also other religious believers came to this place because of its beautiful structure.
