Mărcuța Church, Romanian Orthodox church building in Pantelimon, Bucharest, Romania

Mărcuța Church is a Romanian Orthodox church in the Pantelimon district of eastern Bucharest, built in 1586–1587 under logofăt Dan during the reign of Mihnea Turcitul. The old church keeps a form close to its original one, with 16th-century wall paintings inside, including depictions of armașul Marcu. It stands across the road from Saint Pantelimon Hospital, and the monastery grounds behind the apartment blocks reach the south bank of the Colentina. A second church with the dedications Ascension and Saint Panteleimon was consecrated outside the old enclosure on 3 November 2013.

Logofăt Dan began construction in 1586 under Mihnea Turcitul, and the church was completed in 1587. Vișana, daughter of armașul Marcu, later renovated it, giving the name Mărcuța. Further renovations followed in 1632–1654, 1678–1688 and 1966–1967. The fortified monastery served as a refuge during invasions and as a lazaret during the 1813 plague.

The interior displays wall paintings from the 16th century that tell religious stories and portray local historical figures. These artworks reveal how Orthodox churches served as visual storytellers for people who could not read.

The site remains active for religious purposes and welcomes visitors who wish to observe its historical architecture and medieval wall paintings. Check visiting conditions in advance since the space continues to serve the local community for worship.

The monastery housed a lazaret during the 1813 plague epidemic; from 1829 to 1924 it was the seat of a hospital for the mentally ill, and in 1839 the first mental hospital in Wallachia opened there. Mihai Eminescu was admitted on 2 February and treated with mercury before being transferred to the Caritatea Institute.
