Zamek w Tennenlohe, Castle in Erlangen-Tennenlohe, Germany

Schloss Tennenlohe is a sandstone structure with a mansard roof located at Schlossgasse 7 in Erlangen-Tennenlohe in the Mittelfranken district. The building now serves as a guesthouse and restaurant where visitors can dine and stay overnight.

A high medieval castle stood just southwest of today's building above the Hutgraben; nothing of it survives. In the 14th century the seat belonged to the Lords of Tennenlohe, then to the Lords of Brauneck, and in 1345 to Ullrich Haller von Kalchreuth. The Thirty Years' War destroyed that building; the Peller von Schoppershof replaced it with a new one in 1690. After the Peller died out in 1737 the Volckamer von Kirchensittenbach held it until 1826, and Jacob Gottlieb Volckamer gave it its present form in 1777–1782.

Since 1860 the building has housed a restaurant, so the former manor has been a place to eat and meet in Tennenlohe for over 160 years. The sandstone gate pillars and the 18th-century barn beside it belong to the protected ensemble.

Visitors should check ahead to see if tours or meals are available, as the castle operates primarily as a private guesthouse and restaurant. Access is limited and depends on the establishment's operating hours.

The baroque remodelling of 1777–1782 by Jacob Gottlieb Volckamer is not the oldest part of the site: the medieval castle of Tennenlohe stood just southwest of today's building on a low spur above the Hutgraben, and nothing of it survives. The Volckamer family held the estate until 1826.
