Komturkirche Nieder-Weisel, Religious monument in Nieder-Weisel, Germany.

The Komturkirche is a 13th-century church in Nieder-Weisel, built for the Knights of St. John. Its lower half is dark grey squared stone with an arched doorway and small arched windows; above a horizontal band the wall turns to lighter rubble stone. The steep slate roof carries small dormer vents with red trim, and a pointed arch entrance sits at the left gable end. Inside, a three-aisled hall of four bays once had a hospital ward above it.

The church was built in the 13th century and served the Knights of St. John for their religious and charitable missions. The order's control ended when German authorities confiscated their properties in 1809.

The name reflects its connection to the Knights of St. John, who shaped how the building functioned for centuries. Visitors can see in the layout and stone structure how the order organized the space for their religious and charitable work.

As an active place of worship, the church keeps varied hours throughout the week depending on services and religious events. It's best to check ahead before visiting to confirm current opening times and any special occasions.

This church represents an unusual building approach in Germany, as only a handful of religious structures were built with two distinct levels. This rare design allowed the religious community to combine worship spaces with medical care in a single building.
