Vihara Buddhagaya Watugong, Buddhist temple in Banyumanik, Indonesia.

Vihara Buddhagaya Watugong is a Buddhist temple complex in Pudakpayung, Banyumanik, Semarang, facing the Kodam IV/Diponegoro military base. Its two main buildings are the Dhammasala, a two-storey hall with a five-metre brass seated Buddha resembling the one at Candi Mendut, and the 45-metre Avalokitesvara Pagoda, Indonesia's tallest, built of concrete and brick and painted red. The pagoda has seven levels, eight sides called Pat Kwa, and a five-metre Guanyin statue inside.

The temple was established in 1955, reviving Buddhist practice in the region after centuries of decline. This marked a turning point for the return of active worship and spiritual life in the local community.

The name Watugong comes from a natural rock shaped like a gong, found in front of the security post. The Dhammasala's Thai-style pointed roof and carvings contrast with the Javanese pendhapa architecture around the complex. The pagoda's red paint represents happiness in Chinese tradition, and its eight-sided plan is called Pat Kwa.

The complex sits in Pudakpayung, Banyumanik, directly in front of the Kodam IV/Diponegoro military base. The Dhammasala prayer hall on the upper floor is reached only by an external staircase, as there is no interior stair. The pagoda and worship areas are kept separate from the tourist zones.

The Watugong rock, a natural formation shaped like a gong without human intervention, stands right in front of the temple's security post and gave the complex its name. The Avalokitesvara Pagoda reaches 45 metres, making it the tallest pagoda in Indonesia.
