Csősztorony, Watchtower in Óhegy, Hungary.

The Csősztorony is a two-story rectangular watchtower in Óhegy with a distinctive gabled roof and an attached square observation section. A spiraling staircase connects the residential quarters to the upper lookout area where vineyard monitoring took place.

In 1843 the Pest magistrate held a competition for a vineyard watchtower and an adjoining dwelling after thieves damaged the Kőbánya vines. Ferenc Brein built the tower in 1844 from Lőrinc Zofahl's plans, and it housed the chief vineyard guard. From 1896 the police used it; it gained full monument protection in 1949.

The tower is featured in the coat of arms of Kőbánya district, symbolizing the deep roots of this structure in the area's wine production heritage. It remains a cultural landmark that residents identify with their neighborhood's past.

The tower stands on the southern side of the Óhegy hill area, at the crossing of Harmat, Gitár and Kőér streets. The structure is a national monument, so visitors should treat the building and its carved wooden door with care. The district municipality plans to move the local history collection into the building.
