Bismarck tower, Monument tower in Radebeul, Germany.

The Bismarck Tower in Radebeul is an 18-metre concrete tower clad in local syenite, standing on a three-tiered terrace on a vineyard ridge at 235 m. A square base 8.30 m wide and four metres high carries a round column; four rows of ten-arch arcades quote the mausoleum of Theoderic in Ravenna. Ten pillars support a dome-shaped bowl on top.

The Deutsch-Soziale Reformverein für Radebeul und Umgebung founded a committee in 1902 to build a Bismarck tower on the Lößnitz hills. Funds of 16,000 Goldmark were raised partly by a lottery, with Karl May donating 100 Goldmark. The foundation stone was laid on 30 April 1907 and the tower inaugurated on 2 September 1907. After 1945 Bismarck references were removed; in 1961 it was renamed Turm der Jugend, and in 1993 it regained its original name.

The tower embodies early 20th century architecture and national identity through its monumental form and prominent location. Its construction was part of a broader movement where communities honored this political leader with such structures.

The tower stands on a vineyard summit at 235 m above sea level, above the Hoflößnitz and near the Spitzhaus; the usual approach is via the Spitzhaustreppe staircase. Since 2019 an internal staircase of 83 steps leads up, and the tower has been open to visitors in the summer half-year since 2020. The plateau at its foot offers the view over the Elbe valley.

The hollow interior has eight niches and is open at the top; it was meant to store fuel for fires at planned Bismarck celebrations. A staircase planned in 1913 to feed a fire bowl on the summit was never built for cost reasons, and whether an open bowl stood in front of the tower is not documented. The steel door on the hill side carries the inscription "WIR DEUTSCHE / FÜRCHTEN GOTT SONST / NICHTS IN DER WELT", with a triangular gable above it.
