Preußenturm, Wooden observation tower in Bad Suderode, Germany.

Preußenturm is a wooden observation tower built on Schwedderberg hill near Bad Suderode, close to Quedlinburg. From this hilltop, visitors can see out across the region toward Blankenburg, Quedlinburg, and the Gegensteine hills near Ballenstedt.

The first Preußenturm was erected in 1845, donated by Magdeburg printer August Baentsch. A 12-metre replacement followed in 1885; after World War II it was demolished in the 1940s as unsafe and used as firewood. The present open timber-frame tower was built in 1953 by the Gernrode firm Hulsch, sponsored by Reinhard Jahn, and named Thomas-Müntzer-Turm; it regained the name Preußenturm in 1991.

The tower's name changed with politics: built in 1953 as the Thomas-Müntzer-Turm, it was renamed Preußenturm in 1991 after the political changes. Its weather vane still bears the year 1953, and the tower is stamp point no. 185 of the Harzer Wandernadel hiking badge system.

Several marked hiking trails connect the Kurpark Bad Suderode area to the tower, each with different distances and difficulty levels. Visitors should wear sturdy footwear and check weather conditions beforehand, since the terrain is hilly.

The tower is a stamping point, No. 185, in the Harzer Wandernadel system, so walkers collect its stamp alongside others across the Harz. Its weather vane carries the year 1953, and the 2007 renovation by the Machemehl carpentry workshop inserted new oak beams.
