The Fachhochschule is in sight of the city. The first buildings were built in 1944 and were used by the Nazis to educate the next generation of soldiers. After the war, the complex was not officially used as a school. In the 1970's the university of Trier was re-grounded and used the buildings, until a new university complex was built on the other side of the Mosel valley. Since then the Fachhochschule is using the complex.
