Dohna Castle (German: Burg Dohna, Czech: Donin) on the road from German Saxony to Bohemia was the seat of the burgraves of Dohna. Of the old, once imposing double castle only a few remnants of the walls remain. The ruins of the old castle are located on the hill of Schlossberg near the subsequent suburb of the town of the same name, Dohna, in the district of Sächsische Schweiz-Osterzgebirge in Saxony.
