The Haut-Koenigsbourg fortified castle stands on a rocky outcrop, surrounded by 885 ft (270 m) of ramparts. The accommodations and the donjon extend in the center of the fortress. They are accessed from the lower courtyard, which includes an inn for unexpected travelers, a forge for their horses, and a fountain. A drawbridge provides access to another interior courtyard where a hexagonal spiral staircase leads to the upper floors.
