St. Johannes der Täufer, Church in Hohentrüdingen, Germany

St. Johannes der Täufer is a church in Hohentrüdingen featuring Neoclassical design with a single-nave interior. The building displays clean lines and balanced proportions characteristic of this architectural style.

The church was built from 1817 to 1819 after the ruins of Hohentrüdingen Castle, seat of the imperial counts of Truhendingen and the largest high medieval fortification between the middle Wörnitz and Altmühl, were sold for demolition in 1812. It replaced a castle chapel enlarged in 1711–1720 and demolished in the early 19th century; its 1720 organ case and pulpit survive. The 27-metre keep of the former castle serves as the church tower.

The parish was long served from Westheim and only became independent in 1722; the church's patron is John the Baptist. The organ case of 1720, with its five-part acanthus carving, survives from the predecessor chapel, and the tower can be climbed.

The church stands on a hill in the north of Hohentrüdingen at Schlossweg 2, next to the Haag forest, not in the village centre. The tower can be climbed. The Raingraben rises about 300 metres north of the building and the Maßholdergraben about 250 metres south.

The tower is not a church tower built for the church: it is the roughly 27-metre-high Buckelquader keep of the former Hohentrüdingen castle, with walls three metres thick. It carries an 18th-century polygonal belfry with a clockwork, and visitors can climb it.
