The Drogheda Citadel was a near impenetrable castle on the planet Drogheda. It was the headquarters of the ruling family of the planet, and was only reachable by Sky-sled. During the Drogheda Civil War, the citadel was attacked by the Drogheda Revolutionaries, led by Lando Calrissian and Danu. The current owner of the citadel, Queen Sarna was captured by the rebels and deposed. The citadel then fell into the hands of the new democracy under Sarna's sister, Danu.
