The Château de Hohenbourg is a ruined castle in the commune of Wingen, in the Bas-Rhin département of France. The castle was built on the highest summit of the northern Vosges Mountains, on a sandstone ledge, it comprises a rocky outcrop, approximately square with two matching walls (south and east), a high enceinte with and inner courtyard and manor house, a northern courtyard, a U-shaped barbican with casemates in the north-west, a second barbican, a lower courtyard and ditch to the south.
Access to the castle from the lists, is through two gates (formerly with drawbridges) on the north and south sides of the casemated barbican. The barbican itself contains cannon firing holes and a door to the northern courtyard. Outside, on the south wall, is the Sickingens' shield. In the north courtyard are traces of buildings and stables.
The Renaissance doorway to the inner courtyard has a sculpted doorframe - the Sickingen shield, vines, busts of a couple, heads of a man and a fool. Along the length of the rocky ledge are steps; on the platform there is no trace now of masonry, but cut into the rock is what is thought to be a silo. The inner courtyard is enclosed by a pentagonal enceinte built with dressed stone.
On the north side are remains of a medieval residence with traces of vaulting below the present level. At the foot of the rock is a well dug into the rock with masonry vaulting and traces of a mill. To the south is a cave roomwith an arched doorway. In the corner of the enceinte are the remains of a spiral staircase. Against the southern wall of the enceinte, the ruins of the manor house include a staircase tower whose doorway bears the date 1578 and the Sickingen arms and other rooms
