Schloss Rastbach, Renaissance castle in Gföhl, Austria.

Schloss Rastbach is a Renaissance castle in Gföhl featuring a three-winged design arranged around a south-facing courtyard. The structure spans two levels and adjoins the nearby Rastbach parish church.

Schloss Rastbach was first documented in 1159 and belonged to Hartwich von Lichteneck in 1192. From 1652 Ferdinand Viktor Baron Teufel held the estate; his widow married Ferdinand Ernst Count Herberstein, and the castle stayed with that family until 1805. The Ehrenfels family, owners from 1840, kept it until Rolf Peter Ehrenfels sold it in July 2022 to Stefan Piëch, a great-grandson of Porsche.

The castle is physically connected to the Rastbach parish church, which began as a castle-like structure. The writer Imma von Bodmershof, an owner's descendant, lived at Rastbach from 1924 until her death in 1982. A walled round arch in the east wing is thought to be the former ossuary.

The castle sits in a gentle valley along the Rastbach stream and is easily accessible on foot or by car. Visitors should note that it is private property and access may be limited depending on opening times.

In the east wing, a bricked-up round arch is believed to be the former ossuary, and the adjoining masonry is laid in opus spicatum, a herringbone pattern rare enough to be worth seeking out. The three single-storey farm buildings northeast at the foot of the castle hill date from the 18th and 19th centuries.
