Daun
Daun was a small lordship in the Eifel, centred on the family castle above the river Lieser. The lordship lay between Trier and Cologne.
In 1340 Ägidius von Daun held the town as a fief of King John of Bohemia. In 1353 the archbishops of Trier and Cologne stormed his castle on the pretext that he was a robber baron, and Daun became a vassal of Trier. The family became Imperial counts in 1643; French troops destroyed the castle in 1689, and the comital line died out in the eighteenth century.
