The Hermannsdenkmal is a 19th century monument built to honor Arminius, a Germanic Cherusci chief from the 1st century. It's built inside what remains of a circular rampart near the city of Detmold in central Germany.
200 copper plates riveted together over an iron frame were used to build the structure, which is just over 53 meters in height.
A small exhibit on the monument can be seen in a nearby hut, where the German architect Bandel lived for a time during the monument's construction.
A long distance walking trail goes past the monument and the half a million visitors annually enjoy spectacular views over the countryside.
