The Calvin Reformed Church, entrance on Timotei Cipariu Street, was built in 1902 in English Gothic style.
The building, composed of a prayer room and 11 homes, was designed by architects Nagy Károly jun and Jánosházi László from Budapest.
The church is considered to be a unique monument due to its age and size, as it is the largest gothic hall-type construction from Transylvania and from the Southeastern Europe: the building is 34 meters long and 15 meters wide, and the height of the wall reaches 19 meters.
The furniture is from the 15th century and it was built by several craftsmen from Bistrița. The Rococo style organ, made in Wegenstein Lipót’s studio in 1766, is the second largest organ after the one from the Black Church of Braşov.
The walls of the church are ornate with the richest collection of crests and coats of arms in Romania, belonging to the Transylvanian aristocracy.
From this parish, on the 16th of December 1989, the spark of the revolution was lit with the forced eviction of the minister Tőkés László.
