The Reformed Church with two towers, built in neoclassical style between 1829 and 1859, is the first religious building in Cluj with a modern layout – in the shape of a cross, adapted to the Reformed cult, after the model of the Great Church in Debrecen (Hungary). Georg Winkler, Johann Schilling and Anton Kagerbauer were the architects who contributed to the construction of the building from funds donated by parishioners, clergy and noble families (Radák and Rhédei). The specific silhouette of the church marks the urban street scene, set back from the street line, while the volume and ornaments of the main façade, especially the six Corinthian columns, the tympanum and the high attic, give it a monumental appearance. The interior, dominated by composite pilasters, arches, vaults, the central dome and four galleries, is lit from all directions by semicircular windows. The furniture is uniform, consisting of a pulpit, the Lord's table, pews and parishioners' benches, all the work of local craftsmen.

Worship services in the church have continued uninterrupted from the beginning to the present day. In the community of approximately 2,000 parishioners, two services are held every Sunday, and twice every morning and afternoon during the week. In addition to liturgical occasions, Bible studies and activities for children and young people are held. The singing in the church is led by a cantor-organist, who was in charge of the two choirs, one male and one mixed, and of organising musical events.
