The architectural features of this church connect it with the two most important Transylvanian buildings from the 13th century: the Roman Catholic cathedral in Alba-Iulia and the former Cistercian monastery of Charta, by way of which the Gothic style spread in this region. The interior decoration of the church was completed in the first half of the 14th century. Its Gothic frescoes are among the oldest and best preserved in Transylvania. They are also especially important because of their main theme: the legend about the life of Saint Catherine of Alexandria, who is deeply revered in Central Europe.
