The Polonnaruwa Vatadage, also called the circular house of the relic, dates back to the Kingdom of Polonnaruwa of Sri Lanka and is believed to have been built during the reign of Parakramabahu I. This ancient structure is situated in Dalada Maluva, a quadrangular area. The area is dominated by the vatadage type of Buddhist architecture and features many elaborate stone carvings. Four Buddha statues can also be found here depicting the Dhyana Mudra.
