Archbishop Theoderich von Wied called the Knights of the Teutonic Order to Koblenz in 1216 and donated them part of the grounds of the St. Castor Abbey together with the St. Nicholas Hospital located there. Soon after, a Teutonic Order settlement was established on the site, directly at the confluence of the Rhine and Moselle rivers. The place was first called "Deutscher Ordt" and soon afterwards "Deutsches Eck". With the construction of the Kaiser Wilhelm I monument in 1897, the name "Deutsches Eck" shifted from the site of the Deutschorden branch to the site of the monument, which is today commonly referred to as the "Deutsches Eck". From 1820, the Prussians overshadowed the existing medieval walls with a casemate building bearing the Cross of the Teutonic Order. This building was designed as a bastion to combat a possible attack from the river. In addition, the last Prussian city gate has been completely preserved to this day and now forms the link between Gdansk Freedom and the Blumenhof.
