The Holy Trinity Church (Biserica Sfânta Treime), also known as the Saint Bridget Church (Biserica Sfânta Brigita) is a former Catholic and current Orthodox church in Oradea, Bihor County.
The church was built in 1693 by Bishop Ágoston Benkovich as the first Roman Catholic church constructed after the city was freed from the Ottoman occupation. At that time, the church was dedicated to Saint Bridget from Sweden.
In 1703, the church burned down and by 1722 it was rebuilt again. In 1723 it was handed over to the Franciscan order, who subsequently handed it over to the Pauline order. Later, it was used by the Armenian Catholic community, and in 1786 it was donated to the Ruthenian Greek Catholics of Oradea, who shared the edifice with the Romanian Greek Catholic community. At this time the church received the patronage of the Holy Trinity.
In 1948, the Greek-Catholic church was banned by the communist regime, after which the church became Orthodox. In the following decades, large blocks of flats were built around the church to hide it from the street, something that happened more often following the urban development plans of Nicolae Ceaușescu.
After the fall of the communist regime, the church became a cultural monument, and in 2016 a court ordered its return to the Roman Catholic Diocese of Oradea.
