Wallfahrtskirche Dieburg, Pilgrimage church in Dieburg, Germany

Wallfahrtskirche Dieburg is a white-plastered church with red sandstone window frames and a dark slate roof. Its T-shaped plan joins a single-nave body to a transept, and the elongated Gothic east choir with five tracery windows rises above the nave roof. The west tower ends in an octagonal spire topped by a cross.

A Romanesque basilica is documented in 836, possibly with a free-standing square bell tower whose foundations were found under the south transept. After a fire in 1216 the tower was demolished and replaced by a Marian chapel consecrated in 1232. The side aisles were walled up in the 14th century, and the south transept arm was added in 1697, followed by the north arm in 1712–15.

The church is also called Gnadenkapelle after the Vesperbild on the high altar, a Pietà that has drawn pilgrims since the 15th century. Since 1972/73 a Stationsweg with six terracotta figures by Darmstadt ceramic sculptor Adam Winter (1903–1978) depicts the Seven Sorrows of Mary.

The building sits in the old town and is easily reached via Marienstrasse. As an active place of worship, it welcomes visitors throughout the year, though it is best to check opening times as regular services are held.

The high altar centres on a Vesperbild, a Pietà of the Virgin holding the dead Christ, venerated as a miraculous image since the 15th century; from it the church takes its second name, Gnadenkapelle. The 1930/31 excavations uncovered the foundations of an earlier free-standing square bell tower beneath the south transept apse, possibly a rare German campanile.
