Stadtbefestigung Hainburg an der Donau

Hainburg an der Donau boasts one of the best-preserved medieval town fortifications in Central Europe. The roughly 2.5-kilometre wall ring from the 13th century still encloses the old town almost completely, punctuated by numerous towers and three monumental gates – the Wienertor, Ungartor and Fischertor.

A walk along the town wall leads through well-preserved defences and opens up recurring views of the Danube and the surrounding countryside. The fortifications make Hainburg one of the most striking medieval townscapes in Austria.

The city’s medieval defences stand in Hainburg an der Donau, a town on the southern bank of the Danube in Lower Austria. The walls were mostly built in the first half of the 13th century, with parts possibly paid for by ransom from Richard the Lionheart. The main phase ended around 1230–1240 with the completion of the Hungarian Gate and the Vienna Gate. Later additions included the Fisher Gate in the 13th century and a late-Gothic outer barbican before the Hungarian Gate.

The layout follows western European and Crusader models, and the Heimenburg on the Schlossberg was incorporated into the system. The walls reach up to 12 m in height and 2.2 m in thickness, with varied late-Romanesque stonework and original crenellations south of the Vienna Gate. Ten narrow staircases on the east side lead to the wall-walks, and four main gateways connect to the outer barbican. The ensemble of ditch, barbican and towers survives best on the east side, while the Danube side has buttresses and small flanking towers.

Visitors walk along the largely intact curtain walls and climb the original staircases to the top. The Hungarian Gate and Vienna Gate remain in place, and the Fisher Gate is also preserved. South of the walls a lower curtain with original crenellations runs toward the Schlossberg. The remains of the outer barbican before the Hungarian Gate show the late-Gothic defences. The Danube side displays buttresses and small towers that once supported the river wall.
