Schloss Mattighofen, Medieval château in Mattighofen, Austria

Schloss Mattighofen is a two-story square building with plain facades located at Stadtplatz 1 in the heart of the town center. Today the municipal administration occupies the first floor while a restaurant operates in the western wing, giving the castle ongoing community use.

Mattighofen was first documented in 788 as Matagao, on the site of an Agilolfing ducal estate taken over by the Carolingians. In 1007 King Heinrich II gave the castle and the whole Mattiggau to the Bishopric of Bamberg, whose administrators resided there. From 1517 the Ortenburg counts held it; Christoph's son Joachim had it rebuilt as a Renaissance castle in 1551, adding four corner towers and a brewery. In 1602 the Ortenburgs sold it to the Bavarian dukes for 102,000 gulden.

The name Mattighofen derives from the 788 document form Matagao. Since 17 June 2013 the first floor has housed the Mattighofen town office, and the castle served as one of three venues of the 2012 Bavarian-Upper Austrian state exhibition "Verbündet – verfeindet – verschwägert". In the entrance passage a fragment of a 2nd-century Roman gravestone shows a sacrificial servant with an incense box and a mourning genius.

The location on Stadtplatz in the town center makes it easy to find and access, as the building dominates the main square. Visitors can enter the restaurant in the western wing to experience the interior and see how the castle functions today.

A damaged Roman gravestone from the 2nd century is set into a niche of the entrance passage, showing a sacrificial servant with an incense box and a mourning genius. A carved door frame with the double coat of arms of Ortenburg-Fugger survives at the right-hand entrance, once the way to the inner attic.
