Kirche, Baroque chapel in Kitzingen, Germany

Kreuzkapelle is a Baroque Catholic church in the Etwashausen district of Kitzingen, built from 1741 to 1745 to plans by Balthasar Neumann. It uses Franconian sandstone and a slate roof, with a rounded facade centred on a low tower topped by an onion dome and four bells. The interior is a four-arched rotunda with paired columns, whitewashed and without stucco or paintings.

The Kreuzkapelle was built from 1741 to 1745 to plans by Balthasar Neumann, commissioned by Prince-Bishop Friedrich Carl von Schönborn as a Catholic counterpart to the nearby Protestant St. Michael. It was consecrated on 17 October 1745, exactly 1000 years after the consecration of Kitzingen's Benedictine convent in 745. Neumann's original rotunda design was altered during construction, and the vaulting was simplified by the local site manager.

The name "chapel" is canonical, not descriptive: Heilig-Kreuz was from the start a filial church of St. Johannes across the Main, so church law makes it a subsidiary church, and Franconian usage calls such large filial churches chapels. Every year on the second or third Sunday of October the four-day Etwashäuser Kirchweih (Ebshäuser Kerm) marks the dedication of 17 October 1745, with a parade of marching bands and vegetable-decorated floats; an ecumenical service follows in the chapel on Kirchweih Monday.

The chapel stands in Etwashausen, on the opposite bank of the Main from Kitzingen's old town, so it is reached on foot or by bike across the Main bridge rather than from the centre. The interior is unheated and plain white; the annual ecumenical service is held here on the Monday of the parish fair, the Ebshäuser Kerm, in October.

Although it is called a chapel, the building is a substantial church: it was conceived from the start as a filial church of St. John's parish church across the Main, so canon law makes it a subsidiary church. In Franconia, such filial churches are sometimes called "chapels" despite their size. It is also protected cultural property under the Hague Conventions.
