Bismarckturm, Monument tower in Steinbergkirche, Germany

The Bismarckturm is a monumental tower in Steinbergkirche with a square base and granite stone construction rising about 32 meters high. The structure stands on a hilltop in the Angeln region and features exhibition spaces inside.

Planning for a neo-Gothic tower honouring Otto von Bismarck began in 1899, and donations secured the funding by 1900, when the foundation stone was laid. The 373 name stones built into the tower proved especially effective in fundraising. Stones from the burial chamber of the Räveshoi mound were used in the foundation after the grave was removed. The tower, designed by architect Alexander Wilhelm Prale, was inaugurated on 5 June 1903.

The entrance portal is a projecting stepped gable surround, topped by a marble plaque with an inscription and an 85 cm bronze half-bust of Bismarck with oak leaves and a ribbon, cast by Schäffer & Walcker of Berlin. Below a suggested arch in the masonry sits a rosette with a stylised Prussian shield, now weathered. The tower is the emblem on Quern's coat of arms since 1982 and a landmark of Angeln.

The tower is typically open to visitors between Easter and November, providing access to the exhibition spaces inside. The site is reached by a walking path and offers views across the surrounding countryside of the Angeln region.

The 373 name stones built into the tower were the most effective fundraising device: donors' names were carved into the masonry itself. Stones from the burial chamber of the Räveshoi barrow, a mound on the site, were removed and reused in the tower's foundation.
