Holy Trinity Church (Biserica Preasfânta Treime) is a historic Greek Catholic church in the village of Biertan, Sibiu County. Built in 1856, it served the Romanian Greek Catholic community that had developed alongside the much older Lutheran Saxon population of the village.
Greek Catholics are documented in Biertan from at least 1820, initially without a church of their own. From 1825 they shared the Orthodox church in the village, but as the congregation grew they began raising funds for a separate place of worship. The present Holy Trinity Church was completed in 1856 with contributions from local parishioners, the Greek Catholic Metropolitan Church in Blaj and neighboring parishes.
The church was built of brick in a simple basilica-like form, with the nave, narthex and altar arranged along a straight axis. Its restrained architecture contrasts with the far larger fortified Lutheran church that dominates Biertan, reflecting the different scale and circumstances of the Romanian congregation that built it in the 19th century.
After the Romanian Greek Catholic Church was suppressed by the communist authorities in 1948, the church and parish property were taken over by the state and the congregation was absorbed into the Orthodox Church. The building then served as an Orthodox parish church for several decades. Following the fall of communism, Biertan’s Greek Catholic community reorganized in 1993 and resumed its religious life around the church.
