Ruins located in Polonnaruwa
Tooth Relic Chamber of the 11th Century CE built by King Vijayabahu I (1070-1110). This building was built on 54 stone pillars and the tooth relic was kept on the second floor. The access to the second floor is through a granite stair case, only a few steps remain today. There was three Buddha statues at the bottom and only the center one remains today. Also this is thought to be the only surviving building of the King Vijayabahu I.
'Ata' in Atadage means eight. In this case this building would have been called by this name probably because of it housed eight relics including the main tooth relic or because it was completed in eight days. It is possible that this was built in eight days as there are indications that this building has used parts of other buildings in Anuradhapura era. The moonstone is a good example -this was brought from Anuradhapura to be placed here.
