Heuan Hin: Literally translated as "Stone House", Heuan Hin was constructed during the reign of the Khmer Kingdom under Jayavaraman VII. The Khmer took control of this area from the Champa Kingdom in the tenth century and ruled over it until being replaced by the Lane Xang Kingdom in the thirteenth century. Heuan Hin is believed to have served as one of 121 rest houses along the roads that connected all the lands under Khmer rule. Having been built around the same time, the architecture of Heuan Hin resembles that of Vat Phu in Champasak Province, which sits just to the south of Savannakhet Province.
Today, Heuan Hin shows centuries of neglect and is in a very dilapidated state, but it still serves as a place of worship for local Buddhists. Every year, a festival known as Boun Heuan Hin is held here in March or April, on the night of the full moon. Participants come here to pay respect to their ancestors and Buddhist monks, and to make offerings to the builders of the structure. Locals sell goods to visitors, and much eating, drinking and dancing takes place.
Heuan Hin Quarry: A short distance from Heuan Hin is the quarry where the stone blocks used in its construction were produced. In addition to the cutouts from which the blocks used were taken, completed blocks awaiting transport, abandoned broken blocks, and cuts from unfinished blocks can be found there.
