Lying on the east bank of the Mekong River, a short distance south of Wat Phu Champasak, the Khmer ruins of Wat Tomo, also known as Ou Muang, date from the 9th century. This wat was built in honor of Rudrani, the wife of Shiva, the God of Destruction. The temple is constructed of laterite, and while the best lintels are now in the Champasak Provincial Museum, some artifacts still remain, including a unique mukhalinga, which is an ornately carved lingam (phallic symbol). Situated in a shady forest of tall trees, the wat makes for an excellent day trip from the town of Champasak or Don Daeng. It is also accessible by land from the east side of the Mekong River. In fact, when the water level is high, boats can come within 100 ft (30 m) of the temple, otherwise it is a 15-minute walk from the river in the dry season.
