Burg Frauenberg, Former castle and monastery in Bodman-Ludwigshafen, Germany

Burg Frauenberg, also called Schloss Frauenberg, stands on a rocky spur about 70 by 14 metres, roughly 650 metres southwest of Bodman's church and opposite the Altbodman ruin. The present residential building, used by the Communitas Agnus Dei, incorporates remains of the former castle and has a saddle roof with stepped gables.

The Lords of Bodman, imperial ministerials of the Staufers, built the castle and repeatedly modified it. It served as the family seat until 16 September 1307, when lightning started a fire during a family celebration; the count's family and several Hegau nobles died. The one-year-old Johannes von Bodman survived, and around 1308/09 his grandfather had a chapel with a priest's house built on the destroyed castle site and donated it to Salem Abbey.

The chapel built after the 1307 fire was given to Salem Abbey around 1308/09 by the grandfather of the rescued heir, Johannes von Bodman, in thanks for the boy's survival. Salem expanded the burnt castle into a monastery, and the chapel was reconsecrated in 1515. Today the Catholic community Communitas Agnus Dei lives here, and the old chapel is usually open during the day; visitors reach it by the entrance stairs to the first floor and the corridor beyond, where 15th-century Marian figures and a Pietà are kept.

The site is not a ruin but a former castle rebuilt as Frauenberg Monastery, now lived in by the Communitas Agnus Dei. The old castle chapel is usually open during the day: enter by the entrance stairs to the first floor and follow the corridor to its end. Inside are Marian figures and a 15th-century Pietà.

The sole survivor was the one-year-old Johannes von Bodman: his nurse put him in a large kettle and threw it from a window; bushes on the slope stopped it, and a small obelisk marks the spot today. Among the dead were Conrad, Katharina, Adelheid and Anna von Bodman, Gottfried von Kreyen, Heinrich von Blumegg and the knights Hans von Bodman and Hans von Schellenberg.
