Malakoffturm

Machine-translated from the French article

Malakoff Tower, in German Malakoffturm, is a defensive structure that was part of the Prussian fortifications on the banks of the Rhine, built from 1848 to 1858 in Cologne, Germany. After the consolidation of a series of fortresses upstream of the city of Cologne on the left bank of the Rhine in the 1840s, the expansion of Cologne's fortifications on the Rhine side began in 1848. A new harbour was built opposite the old town to the south, a new wall was installed, and a tower with gate was built at the northern end of the harbour basin, fitted with an iron swing bridge.
