The Ruwanwelisaya is a stupa in Sri Lanka, considered a marvel for its architectural qualities and sacred to many Buddhists all over the world. It was built by King Dutugemunu c. 140 B.C., who became lord of all Sri Lanka after a war in which the Chola King Elara, was defeated. It is also known as Mahathupa, Swarnamali Chaitya, Suvarnamali Mahaceti (in Pali) and Rathnamali Dagaba.

 

This is one of the Solosmasthana (the 16 places of veneration) and the Atamasthana (the 8 places of veneration in the ancient sacred city of Anuradhapura). The stupa is one of the world's tallest monuments, standing at 338 feet (103 m) and with a circumference of 950 ft (290 m). [1]

 

The Kaunghmudaw Pagoda in Sagaing, Myanmar is modeled after this stupa.
