On the road north from Mengwi to Bedugul take the turnoff west to the village of Perean, about 30 km from Denpasar.

Balinese 'meru' are almost always made entirely of wood, but in the compound of the grand old temple here, Pura Yeh Gangga, the body and foundation consist of stone. On three sides of the 'pura' are niches.

On the fourth is a mock door with a stone carving in the shape of a lock. Porcelain plates are embedded in the sides of the temple. Steps from the meru's east side lead up to a narrow terrace. Pura Yeh Gangga is crowned with a seven-tiered thatch roof.

Dating from AD 1334, and first taken note of by the Dutch Archaeological Service only in 1920, the remains of three other small buildings have also been found. The simple temple compound is surrounded by a wall broken by a 'candi bentar'.

Inscribed stones discovered in the vicinity bear the dates AD 1339 and 1429. On the opposite side of the river are several hewn-rock caves, and to the east are the hot springs, Yeh Gangga ('Water of the Ganges'), that gave Perean's temple its name
