It is one of the most important Gothic style monuments in Transylvania, built in the XIVth - XVth century. The church has decorative portals, interior and exterior sculptures (statues, phials, fleurons). There are preserved fragments of XVth century mural painting and a collection of XVIth - XVIIIth century oriental carpets. The church was partially affected by the Great Fire of 1689 which also destroyed a great part of the town and since then the church received the name of 'Black Church'.
