Alt-Schauenburg Castle
# Alt-Schauenburg Castle

Alt-Schauenburg is a ruined castle in the commune of Frenkendorf, Switzerland. It is located near the border of France and Germany, and little of the castle remains because of geological events.

## History

There were two Schauenburg castles near Frenkendorf, Alt (or Old)-Schauenburg about 1 km (0.62 mi) southwest of the village on the top of Chleiflüeli hill and Neu (or New)-Schauenburg to the west. Alt-Schauenburg was probably built around 1275 as the seat of a junior branch of the Schauenburg family. The castle was occupied for less than a century. The 1356 Basel earthquake destroyed much of the castle and shortly thereafter the ruins were abandoned. The ruins were gradually buried, until 1949-50 when they were excavated and repaired. In 1976-77 additional construction helped preserve the site.

## Origin of the name

Neu-Schauenburg was built before Alt-Schauenburg, but because Alt-Schauenburg was destroyed and abandoned first, it came to be known as the old or alt- castle.

## Castle site

Many of the walls are still standing following the two conservation projects. The southern approach was guarded by a shield wall. One corner of the wall was protected by a semi-circular avant-corps. Inside the shield wall, the castle tower and residence hall were rectangular.
