Bismarck tower in Concepción, Chile, German monument on Cerro Caracol hill in Concepción, Chile.

The Mirador Alemán is a granite tower on the summit of Cerro Caracol, with a square base of 10 m² and walls that taper as they rise to 10 m. Its west side, facing the city, bears a stone medallion of Bismarck at a height of 5 m. The upper storey, rebuilt in 2019, has two parallel arches on each of its four sides.

Artur Junge proposed a memorial for German and Chilean war dead in 1918 and donated land on Cerro Caracol. On 12 August 1920 he signed a financing agreement with the Bund Deutscher Turnvereine in Chile, led by German Vogel. The tower, designed by Roderich von Stillfried and built in spring 1921 under John Theune, is the only Bismarck tower in the Americas.

The tower was a meeting place for Concepción's German-speaking community, and the German sports club of Concepción still owns it. A marble plaque added in 1927 lists around 400 German-Chileans who fought in the First World War. The 2019 reopening included a speech by project leader Klaus Bornhardt.

Visitors can reach the monument via a marked path starting from Parque Ecuador, with the route suitable for both hiking and cycling activities. The path involves steady climbing, so appropriate footwear and sufficient time for the ascent should be planned before heading up.

The 1939 Chillán earthquake destroyed the tower's upper floor, which was later removed; the 1960 and 2010 quakes cracked the walls, especially on the north side. Because it was built of stone without iron reinforcement, it is still called "the earthquake-resistant tower" on the Bismarckturm website. Its second floor was rebuilt and the tower reopened on 22 November 2019.
