The Ruwanwelisaya is a stupa and a hemispherical structure containing relics, in Sri Lanka, considered sacred to many Buddhists all over the world. Two quarts or one Drona of the Gothama Buddha's relics are enshrined in the stupa, which is the largest collection of his relics anywhere. It was built by King Dutugemunu c. 140 B.C., who became King of all Sri Lanka after a war in which the Chola King Elāra was defeated. It is also known as "Mahathupa", "Swarnamali Chaitya", "Suvarnamali Mahaceti" and "Rathnamali Dagaba".
This is one of the "Solosmasthana" and the "Atamasthana". The stupa is one of the world's tallest ancient monuments, standing at 103 m and with a circumference of 290 m.
