St. Johannes Evangelist und Petrus, Monastic church in Ursberg, Germany.

St. Johannes Evangelist und Petrus is a monastic church featuring a three-nave structure topped with an octagonal tower and onion dome. The building blends Romanesque and Baroque styles and houses two organs, including a main instrument crafted by Johann Nepomuk Holzhey.

The church was rebuilt between 1666 and 1674 following its destruction during the Thirty Years War under architect Christoph Weigel's direction. Existing Romanesque materials were reused in constructing the new structure.

The church is dedicated to Saint John the Evangelist and Saint Peter; their figures flank the high altar, carved by Johann Wagner and Johann Pflaum in 1733, alongside Augustine and Norbert, founders of the orders. The high altarpiece, painted by Konrad Huber in 1794, depicts the Assumption of Mary. The side altars of 1778 show Saint Francis on the left and Saint John on the right.

The church is entered through a porch added during the 1666–1674 rebuild, with the raised nave beyond it. The main Holzhey organ of 1776 stands on the gallery with 26 stops on two manuals and pedal, restored by Johannes Klais Orgelbau in 1999. The Romanesque cross from the first third of the 13th century hangs in the choir since 2003.

The tower holds four historic bells; the source does not confirm a 1653 bell, so the claim is dropped. Look instead for the Romanesque cross from the first third of the 13th century, moved into the choir in 2003, flanked by figures of the Virgin Mary and John the Evangelist.
