The Concathedral of St. Nicholas (Slovak: Konkatedrála svätého Mikuláša) is a Gothic hall church in downtown Prešov, eastern Slovakia, dedicated to Nicholas of Myra. Since 2008 it has been the co-cathedral church of the Archdiocese of Košice, before that it was just a simple parish church and known as the Cathedral of St. Nicholas. The church is 54.7 meters long, 34.45 meters wide, 16 meters high and the tower measures 71 meters.
The predecessor of today's church was built in 1230 and was replaced in 1347 by today's parish church, which had a nave with a tower. 1502-1515 the cathedral was redesigned in late Gothic style and two side aisles were added under the direction of the municipal master Ján Brengyszey. During the Reformation the church was the scene of several important events. In the years 1531-1671 the acceptance of Protestantism took place, 1682-86 the uprising of Emmerich Thököly and 1705-1711 the uprising of Franz II Rákóczi.
Only minor repairs were carried out in the 17th and 18th centuries, such as the baroque south portal. The church burned down in 1685, 1711, 1780, 1788, 1886 and for the last time in 1887. After the fire of 1788, the classical main portal was built. The tower was then re-Gothicized in 1903-04. A major repair came in the 1950s and the church received travertine paving, a new facade, new stained glass and a Way of the Cross. The last repair to date was carried out between 1982 and 1989.
Little has survived of the original Gothic and Renaissance furnishings, most having been destroyed by fire, particularly during the 17th century uprisings. For example, some works by Master Paul von Leutschau are Gothic, such as sculptures of angels from the beginning of the 16th century. However, many Gothic elements have survived to this day, such as net vaults, windows and portals. The baroque Saint Nicholas altar from 1696 (Wikipedia) dominates the interior.
