Teile der Stadtbefestigung, Medieval fortification walls in Wiener Neustadt, Austria.

The city fortification sections of Wiener Neustadt consist of towers and wall segments that once enclosed the medieval town. The remaining structures stand approximately eight meters high and are visible at several locations around the old town on all sides.

The walls were laid out on 24 May 1192, the day Duke Leopold V of Babenberg was enfeoffed with Styria, and building began in the last decade of the 12th century. The first quarter of the 13th century added four corner towers, ten intermediate towers and four gates. In the mid-15th century a crenellated wall-walk and six towers in ashlar with bossed corners followed; the 16th and 17th centuries brought new towers and bastions.

The wall's name lives on in the street layout: the four medieval gates were demolished between 1851 and 1873, and their coat-of-arms stones were set visibly into the facade of the Rathaus. The Reckturm at the northwest corner and the Stubenberger Turm on the south wall are the surviving towers most easily seen on a walk around the old town.

The fortification sections are scattered throughout the town and can be visited on foot, with the Reckturm tower and wall segments near the former Wiener Gate being the most notable. A walking tour around the old town perimeter is the best way to see these remains across different locations.

During the 1550s, an underground casemate system was built at the southwest corner to serve as a hidden weapons storage facility. These vaulted chambers were carefully integrated into the fortification and show the sophisticated military engineering of that period.
