Burg Königsegg, Castle ruin in Königsegg, Guggenhausen, Germany

Burg Königsegg is a castle ruin in the Königsegg hamlet of Guggenhausen, in the Ravensburg district of Baden-Württemberg, not Bavaria. Three buildings of the former complex survive, the rest having been rebuilt in the 16th and 17th centuries and abandoned as a residence from the mid-17th century.

Burg Königsegg was built by the lords of Königsegg, a branch of the lords of Fronhofen, as their ancestral seat and was first mentioned in 1251, when Eberhard von Fronhofen took the name Eberhardus de Kunigsegge after the castle. It was rebuilt in the 16th and 17th centuries, but from the mid-17th century its owners no longer lived there. Until 1850 the castle belonged to the municipality of Hoßkirch.

The name Königsegg comes from the noble family von Königsegg: in 1251 Eberhard von Fronhofen took the name Eberhardus de Kunigsegge after the castle, founding the line. The ruin lies in the Königsegg hamlet of Guggenhausen, which was part of Hoßkirch municipality until 1850.
