The Unitarian church of Călușeri initially was built of wood and it served the followers until 1762.

The believers got the permission of Maria Theresa for the building of a new wooden church, but the leaders of the church decided not to obey this restriction and at the proposal of Nagy József they erected a stone church already in the year 1762. However, following a denunciation they were not allowed to use the church for eight years. The tower of the church was built in 1783.
