Schloss Aschbach, Baroque castle in Schlüsselfeld, Germany.

Schloss Aschbach is a two-storey, two-winged sandstone ashlar building with a hipped roof, set on a slope about 10 metres above the village of Aschbach. An 18th-century courtyard wall with a gate bearing the Pölnitz coat of arms encloses the front court, where a fountain stands. The east wing has a round stair tower and a courtyard with an arcade.

Following damage during the Thirty Years' War, General Hieronymus Christoph von Pölnitz rebuilt the castle between 1677 and 1697, using the original foundations. This reconstruction represented the region's return to stability and prosperity in the decades after the conflict.

The castle gate on the road bears the Pölnitz family coat above its two stone pillars, and a second coat of arms hangs over the east wing entrance. The park gate is topped by stone pillars carrying fruit baskets. The baroque garden behind it holds terraces, vases, busts on pedestals, stairs and walls, plus a garden pavilion with a grotto fountain from the mid-18th century.

The castle remains private property of the Pölnitz family and is closed to visitors. The surrounding 5-hectare park can be viewed from outside the grounds but is not open for public access.

During World War II the castle functioned as a storage facility for artworks from museums fleeing the conflict. After the war it also provided shelter to Polish Jewish refugees traveling toward Israel.
