Schlosskapelle Herten, Gothic chapel at Schloss Herten, Germany

The Schlosskapelle Herten stands on the Vorburg area of Schloss Herten, not on an island in the moat. It is a brick building with white exterior paint, pointed-arch windows, low buttresses along the sides and choir, and a slate roof topped by a small ridge turret with a cross. The portal porch on the gable front bears the year 1747; a free-standing portal on the approach path, designed by Johann Conrad Schlaun in 1735, was the main portal of Schloss Grimberg and was placed here in the 1960s. Inside, a three-aisled hall of two bays carries cross-ribbed vaults on columns and wall consoles, leading to a single-bay choir with a 5/8 close.

The chapel dates to 1328, when Wennemar von Grimberg founded memorials there; around 1560 Heinrich Knipping renewed the interior in Renaissance style. In 1907 the Droste zu Vischering family sold Grimberg Castle for the Grimberger harbour, and in 1908 they had the chapel dismantled stone by stone and rebuilt on the outer bailey of Schloss Herten. War damage and mining subsidence followed; the LWL took over the site in 1974 and restoration reopened the chapel in 1980.

The chapel was used by Herten's Greek Orthodox community until mid-2004; since September 2004 it has hosted events for the Protestant pastoral care of the LWL psychiatric clinic. Volunteers keep it regularly open, and it is used for weddings and baptisms. The epitaphs of Bertram von Nesselrode and Lucia von Hatzfeld, carved 1680/81 by Johann Mauritz Gröninger in Baumberg sandstone, came from the old Herten parish church.

Access to the chapel is through guided tours that include the castle complex and explain the architectural features in detail. Visitors should check with the castle administration for current visiting hours and tour availability.

The free-standing portal on the path to the chapel was originally the main portal of Grimberg Castle, designed by Johann Conrad Schlaun in 1735. It was moved to its current location in the 1960s. The chapel's portal porch bears the year 1747, likely marking the end of Schlaun's renovations.
