The stupa is located on Phousi (Hermit Mountain), at a height of approximately 150 m. It was built by King Anourouth (reigned 1791–1817) in 1804 and renovated in 1914. During a reconstruction of the temple in 1926, a new stairway consisting of 328 steps leading up to the stupa was added.
The 20 m high stupa is in the shape of a square vase in typical Lao style. The base consists of three square unadorned layers painted in white. The middle layer has a small white stupa at each corner. The stupas are in the shape of lotus buds and have gilded spires. The top layer is surrounded by a fence and gilded canopies stand at the corners. The lower part of the stupa, which takes up approximately half its height, consists of a square Sumeru throne with an octagonal trim. The upper part is in the form of the two-tier vase-shape stupa body. The spire is similar in design to the four gilded canopies at the corners.
