Castle Heimenburg, Hainburg an der Donau

Castle Heimenburg is a ruin perched on a hilltop in Hainburg an der Donau. The remaining stone walls show the outline of the fortress and offer views across the Danube River and the surrounding countryside.

Emperor Henry III ordered the construction of this fortress in 1050. Over the following centuries, the structure was reinforced and expanded to protect the regional border.

The castle chapel served as a venue for important regional ceremonies and gatherings. Today visitors can still see traces of this religious function in the remaining stone foundations.

The site is reachable via marked hiking trails from Hainburg an der Donau. Information panels on location explain the ruins and their key features.

A lightning strike in 1569 triggered an explosion in the castle's powder storage, causing severe structural damage. This event hastened the fortress's decline and shaped its current condition.
