Cornelienkirche, Gothic church in Bad Wimpfen, Germany

Cornelienkirche is a single-nave church built of unplastered rubble stone with a rectangular plan, buttresses and windows along its long sides. It has no tower, only a small roof turret, and a blocked chancel arch in the east gable. Inside, a neo-Gothic leaded window shows Christ in a mandorla above a plain stone altar with a wooden crucifix.

A church dedicated to Mary is documented from the 14th century and was first called Cornelienkirche in 1444. The present building was begun or rebuilt from 1476, as an inscription on the north portal states, with the patronage held by the Worms Cathedral chapter. The name probably goes back to the belief, spread by Dean Burkard von Hall's chronicle in the late 13th century, that the Roman settlement was called Cornelia.

Locals call it Tillykapelle because Tilly is said to have planned the battle deployment here on 6 May 1622. The name Cornelienkirche does not go back to Saint Cornelius: it likely stems from the belief, spread by Dean Burkard von Hall's late 13th-century chronicle, that the Roman settlement was called Cornelia. The church was long used as a hay barn from 1740.

The church stands east of the old town of Wimpfen im Tal, on the road toward Heilbronn, right where the Elsenztalbahn bridge crosses the street; it lies at about 150 m, the lowest Protestant church in Württemberg. The Neckar flooded it repeatedly, most recently in 1993, after which the embankments were reinforced. A former cemetery beside it served Jagstfeld across the river.

The church is also called Tillykapelle: tradition holds that Tilly had his headquarters here during the Battle of Wimpfen on 6 May 1622 and drew up the battle plan inside. The name Cornelienkirche does not go back to Saint Cornelius; it likely stems from a belief recorded in Dean Burkard von Hall's late 13th-century chronicle that the Roman settlement by the Wimpfen fort was called Cornelia.
