Alfter Castle: architectural highlight and landmark.
The origin of the castle goes back to the 12th century. After repeated destruction and makeshift reconstruction, the castle was converted into a baroque palace in 1721. The two-storey manor house with the flanking towers was largely based on the style of the previous buildings, and a three-winged outer castle was also built. Since 1188, the office of the hereditary marshal of the Electorate of Cologne had been connected with Alfter Castle. In 1445, the castle came into the possession of the former counts and later princes of Salm-Reifferscheidt-Dyck.
Until 2009, the castle was home to the architecture department of the nationally renowned Alanus University of Arts and Social Sciences, which is now housed on Campus II of the university on Bonn-Brühler-Strasse.
