The origins of the Alfter palace go back to the 12th century. After it was destroyed many times and each time rebuilt provisionally, in 1721 the castle site was converted into a Baroque palace. The two-floor manor flanked by towers was largely based on the style of the previous buildings, but a lower castle with wings was added. The office of the Elector of Cologne's hereditary Marshall has been associated with Schloss Alfter since 1188. In 1445 the site came under the ownership of the Count and later Elector zu Salm-Reifferscheidt-Dyck.
