St. John’s church was built in the first quarter of the 13th century as part of the Benedictine monastery complex. The first indirect written mention of the monastery appeared in 1221, and another, already direct record, only from 1397, when the local abbot was recorded. The monastery was dissolved in 1548-1580, probably as a result of wars and the ongoing Reformation. In the 17th century, the church was severely damaged, with the upper parts of both towers completely destroyed. In the first half of the nineteenth century, it fell into decline, and in 1857 its roof collapsed due to neglect and lack of renovation. Only in the years 1875-1876 a major reconstruction took place, financed by a nationwide fundraiser. Unfortunately, however, there was not enough money to complete the towers. Work was carried out to bring the church into a form similar to the original, Romanesque.
The original Romanesque church was a single-nave structure with a two-tower west facade, a rectangular chancel on the eastern side, the same width as the nave, ended with a semicircular apse. As the four-sided towers were situated on the south and north sides of the nave, the church received a very wide facade, suggesting a three-aisle nave behind it, and in fact hiding only a single nave (layout similar to the churches in Bína and Bzovik). The church was built using a technique that was relatively rare in today’s Slovakia, with walls made of large, carefully worked blocks.
Three portals led to the church. The main one was the impressive west portal with two steps that smoothly turned into a semicircular archivolt. The southern portal in the nave had one step into which flanking columns with capitals were probably inserted. The northern entrance was even simpler, narrow and without steps, closed in a semicircle. The entrance from the monastery buildings was also identified in the north wall of the north tower.
Inside the church, the choir was separated from the nave by a semicircular chancel arcade, set on a pedestal, above which two heavy cornices were created in the upper part. On the sides of the arcade, in the nave part, there were placed semicircular recesses, which were originally related with the side altars. Since the monastery and the church were founded by a private patron, there was a gallery between the towers in the nave, illuminated by a round window on the west side.
The monastery buildings, which were added a little later on the northern side of the church, apparently formed a typical enclosure complex with a central patio surrounded by a cloister and residential buildings. The eastern wing was two-story. Probably according to the typical Benedictine layout, it housed a chapter house on the ground floor and a dormitory on the first floor.
Thanks to the nineteenth-century renovation, the church has survived to modern times, although without the two western towers. The effects of these works are, among others, the neo-Romanesque gables of the nave: eastern and western with a small belfry and a restored under-eaves frieze. The paintings inside the chancel and apses are neo-Gothic, while the nave is covered with a early modern coffered ceiling.
From the original Romanesque architectural details, two eastern windows on the south side (one illuminating the nave, the other in the choir space) have been preserved. The apse window and the round window on the west façade are also original. There are three primary portals leading to the nave, although the entrances in the southern and northern walls are bricked up and the western tympanum is neo-Romanesque. The monastery buildings have not survived, only the imprint of the roof of one of the wings is still visible on the northern facade of the church.
