Phra That Si Song Rak

Phra That Si Song Rak (Thai: พระธาตุศรีสองรัก, literally means the Stupa in Honour of Two Loves;(Lao: ພຣະທາດສຼີສອງຮັກ)Phra That Sri Song Hak in Lao, and varied other spellings) is a Buddhist stupa built in c. 1560 by King Setthathirath of Lan Xang and King Maha Chakkraphat of Ayutthaya.

It is located on the Man River in Dan Sai district, Loei province of modern-day Thailand, 30 kilometers (20 miles) from the modern Thailand-Laos border.

At some point it was shattered into fragments, and the remnants are maintained at Haw Phra Kaew Museum.

The stupa is roughly 20 meters (66 feet) tall and 9 m (30 ft) wide at the base on each side.

Locals have held an annual offertory ritual and celebration at That Sri Songrak every May 15 for centuries.
