Bucur Church, Orthodox church in Sector 4, Bucharest, Romania.

Bucur Church sits on a hill with simple white walls and a wooden-posted entrance porch near Radu Voda Monastery. The structure displays basic Orthodox church design with a straightforward layout focused on its function as a place of worship.

The building was first documented between 1844 and 1846 and underwent major renovations from 1909 to 1910. These works transformed the exterior appearance and several of its architectural features.

The church honors Saints Cyril of Alexandria and Pope Athanasius I, reflecting Orthodox religious practices that have shaped local spiritual life. This dedication shows the deep connection between the community and early Christian theology.

The church stands at 33 Radu Vodă Street in Sector 4, on a rise separated from the Radu Vodă Monastery hill by the street cut through in the 18th century. The entrance is through the wooden-posted porch, and the carved stone frames on the door and windows date from the 1909–1910 restoration.

The name connects to Bucur the Shepherd, mentioned in a 1761 manuscript by Catholic missionary Blasius Kleiner. This reference suggests a possible link to the early founding stories of Bucharest itself.
