The castle of Haut-Koenigsbourg looms among the fir trees on a rocky outcrop standing over 2,480 ft (750 m). Its donjon surmounted by the imperial eagle of Kaiser Wilhelm II affirms its dominance. Since the Middle Ages, it has watched over the large plain of Alsace that stretches out at its feet. It was the object of numerous covetousness and excuse for a war between the Bishop of Strasbourg and the Duke of Lorraine. Destroyed in 1633 during the Thirty Years' War, it remained unoccupied for more than two centuries. The medieval nostalgia of Wilhelm II brought it back to life in 1908.
