Daun
Daun stands above the Lieser valley in the volcanic Eifel. Its prominent basalt hill was fortified in antiquity and later became the site of a castle of the lords of Daun. The town was first described as such in 1337 and received town and market rights in 1346, when it also became the seat of a high court. In 1712 the elector of Trier built an administrative house on the castle hill. French occupation began in 1794, and Daun passed to Prussia in 1815.
