Burg Bocksberg, Medieval castle ruins in Laugna, Germany.

Burg Bocksberg is a ruined hilltop castle above the Laugna hamlet of Bocksberg in the Dillingen an der Donau district of Swabia. A deep arched neck ditch cuts off the stepped main castle cone, whose plateau preserves the stump of a keep built of smooth Nagelfluh blocks, about 9.25 m square with 1.75 m thick walls and roughly 8 m high at the northeast corner. North and east of it, a broad lower terrace carried the former outer bailey, now leveled as a festival ground.

The castle was probably built in the early 13th century as the seat of the Lords of Bocksberg, who are documented there from 1231 to 1322; the family likely died out in the 14th century. The Marschalken von Bocksberg then held the castle as ministeriales of the Bishopric of Augsburg. In 1462 it was destroyed in the Second War of the Cities, and after severe damage in the Thirty Years' War it was not rebuilt.

The castle grounds were inhabited and shaped by different Augsburg patrician families over many centuries. Visitors can still see traces of this changing ownership in the structure of the site today.

The site now functions as a festival ground with electrical infrastructure that allows it to host public events. You can visit at any time, as the hilltop and its remains are freely accessible to the public.

The main castle plateau preserves the foundations of a former residential tower built with smooth conglomerate stone blocks. These carefully shaped blocks reveal the craftsmanship of medieval builders.
