Schloss Matzen, Medieval castle in Reith im Alpbachtal, Austria.

Schloss Matzen stands on a low hill spur above Reith im Alpbachtal. Its elongated north and south wings are joined by a short western tract, and a round six-storey keep rises at the east end. The lower courtyard is framed by four-storey arcades with round and octagonal marble columns from the second quarter of the 16th century.

This castle was first mentioned in 1167 when it was under the rule of the Knights of Frundsberg. The site had earlier importance because a Roman post called Masciacum once stood there.

The castle chapel was consecrated on 23 November 1176 by Archbishop Conrad of Wittelsbach. Its altar with a wooden crucifix, dated 1500 and once attributed to Veit Stoss, has been in the Tyrolean State Museum since 1978. The courtyard arcades with round and octagonal marble columns date from the second quarter of the 16th century.

The grounds have a café and restaurant open Wednesday through Sunday with outdoor seating near a fish pond. Visitors should allow time for a walk across the property and wear sturdy shoes.

During World War II, this castle served as a shelter for valuable collections from the Tyrolean State Museum Ferdinandeum and a Tyrolean library. These artworks and books were kept safe from possible war damage here.
