Óhegy park, Urban park in Kőbánya, Hungary

Óhegy Park is a 20-hectare public park in the Óhegy district of Kőbánya, Budapest, created on the site of former brick-clay pits and mining tunnels. It includes playgrounds, an arboretum, and a sunken area in the southeast corner that recalls the former mining use. The park is named after the 148-metre Ó-hegy hill, whose highest point it occupies.

Vineyards covered the hill in the 19th century, and the Csősztorony watchtower was built for them; brick factories such as the Virava works later worked the quarry, and the last factory closed in 1965. Filling of the pits with rubble and municipal waste ran through the 1950s and 1960s. Work on the 20-hectare park began on 13 February 1973 and it opened in 1975 as the Hungarian-Soviet Friendship Park, renamed Óhegy park after 1989.

The park opened in 1975 as the Hungarian-Soviet Friendship Park, nicknamed Baripark, and was renamed Óhegy park after the regime change. In the southeast corner a small bay-like hollow marks where the ground collapsed on 7 June 2004; since the tunnels were sealed in 2012, a dog run has occupied it.

The site is accessible via an illuminated running track open to visitors at all times. Separate zones allow comfortable dog walking and outdoor training without interference.

Underground tunnels from former mining operations run beneath the park and require regular monitoring of ground stability. These hidden structures quietly influence how the park is maintained and managed.
