The Unitarian Church is the only Christian denomination that was born during the Reformation in a different geographical area than that of Western Europe. An important part of the Hungarian community in Transylvania adopts Unitarianism, the Unitarian confession founded by Pastor Francisc David taking over the main Roman Catholic churches in the Cluj area. With the entry of Transylvania under the jurisdiction of the Habsurg Empire, the Unitarian denomination is forced to return the churches, and for about 75 years the liturgical service will take place in private homes.
The architect Anton Turk from Vienna supervised between 1791-1796 the construction of a cathedral for the Unitarian confession. The building was made in the late Baroque style, in the form of a nave, the total length being 40 meters, with classicist and rococo elements. This church is the only worldwide episcopal cathedral of the Unitarian denomination.Â
