The settlement of the Teutonic Order at the confluence of the Rhine and Moselle rivers in 1216 gave this historically significant place its name "Deutsches Eck". Koblenz also owes its name to the confluence of the Rhine and Moselle. Over the course of time, "Castellum apud Confluentes", Latin for "the fort at the confluence", transformed into the present-day name of Koblenz.
On 31.08.1897, the copper monument to Kaiser Wilhelm I was ceremoniously inaugurated in the presence of Kaiser Wilhelm II.
Destroyed by artillery fire in March 1945, Theodor Heuss rededicated the riderless pedestal as a memorial to German unity in 1953. Until 1993, a flagpole with the German federal flag was enthroned here. Finally, in autumn 1993, a reconstruction of the monument was raised onto the plinth. Today, the 37-metre-high monument–14 metres of which are accounted for by the equestrian statue showing Emperor Wilhelm I with a genius–attracts more than 2 million visitors a year and has been part of the UNESCO World Heritage Site "Upper Middle Rhine Valley" since 2002.
