Cultural heritage D-2-7540-0015 in Bodenkirchen

A medieval castle once stood near Bonbruck, a village in Bodenkirchen, Lower Bavaria. Called Langquart, it occupied a low-lying site beside the Bina stream where travellers crossed by ford or causeway. The name itself means ‘long approach through marshy ground to a bridge’. Written records first mention the Hofmark in 1492 when Simon Reikher held the estate. The castle passed through several noble families over three centuries. Heinrich Neuburger, a 17th-century court official from Osterhofen, owned it for forty-four years. Later owners included the counts of Cessana and Colle, and finally the Freiherr von Guggenmoos. By 1780 the site was already described as an inherited manor rather than a fortified house. Today nothing remains above ground. The rectangular platform, once surrounded by a seven-metre-wide moat, lies beneath a meadow beside the Bonbruck sports field. A 17th-century engraving by Michael Wening shows a four-storey timber building with steep roofs and corner turrets, reached by wooden bridges. The vanished castle is registered as a protected archaeological monument.
