Although Vulcan belongs to the smaller municipalities in the Brasov region, the church-fortress displays a relatively large enclosure with diameters ranging from 67m to 49m. One can assume that the chancel arch comes from an earlier Romanesque church to which a Gothic, buttress-supported, stone-rib-vaulted choir was built in the 15th century. The ribs rest on human-masked corbels. The church was destroyed by Gabriel Bátory’s troops (Prince of Transylvania) in 1611 and left in ruins for 54 years. It was rebuilt in 1665. The church hall got a coffered ceiling.
