Dionysiuskirche, Protestant church in Grunbach, Germany

Dionysiuskirche is a church building in Grunbach with an octagonal tower and late Gothic elements. The choir is crowned by a ribbed vault ceiling, while the church is surrounded by a ring wall with support pillars.

The building was erected in 1481 on the foundation of an earlier structure from the 11th century. In 1863, the church received Gothic modifications by architect Christian Friedrich von Leins.

The church is named after Saint Dionysius, to whom it was dedicated in 1451; in 1537 Veranus was added as a second patron. The wrought-iron gate to the churchyard, made by Stuttgart artist Wolf-Dieter Kohler, depicts the Psalm verse "The bird has found a nest" (Psalm 84:4). The modern baptismal font below the pulpit was donated by Grunbach citizens in 1964.

The church stands within a fortified churchyard ringed by a wall that has strong buttresses on the sloping east and south sides. In the south wall look for two stone crosses carved with a vintner's knife, the "Horbe", and a medieval village lock-up known as the "Karräsperle". The three-storey tower rises 37 metres and is pierced by loopholes and light slits.

The oldest surviving item is not the font in use but a deep Romanesque basin from around 1200; the modern font below the pulpit was donated by Grunbach residents in 1964. The south wall also keeps wall paintings from around 1500, showing two kneeling angels with inscribed bands, whose old contours and hands survive while the restored parts are hatched in a modern manner.
