Atadage Dalada Maligaya is the house of the tooth relic of Buddha built by King Vijayabahu I (1070-1110). This building is built on 54 stone pillars. The tooth relic has been kept on the second floor probably made out of wood. The access to the second floor is through a granite stair case. Few steps still remains of this staircase which led to the upper chamber of the building. There has been three Buddha statues at the bottom and only the center one remain today. Also this is thought to be the only surviving building of the king Vijayabahu I.
