Blankenheim Castle

Blankenheim Castle (German: Burg Blankenheim) is a schloss above the village of Blankenheim in the Eifel mountains of Germany. It was built as a hill castle around 1115 by Gerhard I and became the family seat of the House of Blankenheim. The lords of Blankenheim were elevated to the countship in 1380. The counts were related to the counts of Manderscheid and, from 1469, were named Manderscheid-Blankenheim. With the extinction of the lines of Manderscheid-Gerolstein and Manderscheid-Kail (1742) the County of Manderscheid became the largest independent territorial lordship in the Eifel.
