Introduction to the stone Buddhist temple: The stone Buddhist temple is called Thuparamaya. It is the smallest and oldest Buddhist temple in the ancient city of Polonnaruwa, and it is also the best-preserved stone Buddhist temple. The entire architectural appearance of the Buddhist temple belongs to the architectural style of the period of Emperor Parakarama Pahu and Nisan Kamala. It is very similar to the style of Angkor. It is a place of pilgrimage for Buddhists. But what is very interesting is that this Buddhist temple only has one door and some imaginary window lattice, but no real windows.
