Reckturm, Medieval defense tower and weapons museum in Wiener Neustadt, Austria

The Reckturm is the northwest corner tower of Wiener Neustadt's former city wall, built in the early 13th century and rebuilt in 1902 in its presumed mid-15th-century form. Its three floors and a cellar rediscovered in 2004 hold a weapons and torture museum run by the Wiener Neustädter Denkmalschutzverein since 1957.

The Reckturm is the northwest corner tower of Wiener Neustadt's former city wall and dates from the early 13th century. From the beginning of the early modern period it was used as an office and prison, notably for the Peinliche Befragung (judicial interrogation under torture), which gave the tower its name. Around the end of the 19th century demolition of the tower and the surrounding wall began; in 1901 the art historian Franz Staub had the work stopped and reconstructed the tower, completed in 1902, probably in its mid-15th-century form. It is the only surviving corner tower of the former fortification.

Since 1957 the Wiener Neustädter Denkmalschutzverein has run a small weapons and torture museum on three floors of the tower, and more recently in a cellar rediscovered in 2004. On show are firearms from 1630 to 1950, historical edged weapons and equipment of the k.u.k. Army. The tower's name recalls its later use as an office and prison, especially for the Peinliche Befragung, judicial interrogation under torture.

The tower is located at the corner of Reyergasse and Petergasse in the city center and is relatively easy to reach on foot. It is recommended to check opening hours before visiting, as access may be limited seasonally.

In 1901, art historian Franz Staub saved the tower from demolition and initiated a reconstruction based on 15th-century specifications. This restoration is considered one of the early examples of heritage-appropriate renovation in Austria.
