Bismarck tower in Lębork, Bismarck tower in Lębork, Poland.

The Bismarck Tower in Lębork is a square-plan tower on a hill in Bolesław Chrobrego Park, with a small oval turret at one corner of its top. It was designed as a multi-purpose structure: a monument, an observation point and a water tower, and a restaurant once occupied its lower part. In 2019 a modernist glass-and-aluminium annex was added, which drew public protests.

The tower was designed as a multi-purpose structure combining a Bismarck memorial, a viewing point and a water tower, with a restaurant in its lower part. The restaurant operated until the 1960s, after which the building stood closed and decayed for years; the adjoining restaurant building was demolished in 1993. From 2014 the city planned a revitalisation, completed in 2019 with a modernist glass-and-aluminium annex that drew public protests.

The tower's name recalls Otto von Bismarck, and it stands in Bolesław Chrobrego Park on a hill in the eastern part of Lębork. Its lower level once housed a restaurant, which operated until the 1960s; the adjoining restaurant building was demolished in 1993. A small oval turret sits at the corner of the top.

The tower stands on a hill in the eastern part of Lębork, in Bolesław Chrobrego Park, and is reached on foot through the park. The 2019 glass-and-aluminium annex marks the entrance side; the structure still works as a water tower, so the interior is not open to visitors.

The beacon was not inside the tower but mounted on top of the small oval turret at the corner of the roof, shining vertically upward. It served as a landmark for aircraft on the Königsberg–Berlin route during the interwar period.
