The Sababurg, first called the Zappenburg, then Zapfenburg and today, after the Brothers Grimm fairy tale Sleeping Beauty Castle , is the ruin of a hill castle in the legendary Reinhardswald, a forested upland that runs through the North Hessian county of Kassel. Sababurg is also the name of a district of the town of Hofgeismar in which the castle is found.
The hill castle appears in 1334 as the Zappenburg to protect pilgrims to the nearby pilgrimage site of Gottsbüren. In 1490, the hunting lodge of Zapfenburg grew out of the medieval castle site. After 1957 the site was restored and since 1959 it has housed an hotel. Together with the Trendelburg and Krukenburg the present ruins belong to the three best known castles in the Reinhardswald region, although the latter is just outside this forest. In the surrounding area is the Sababurg Wildlife Park and the virgin forest of Urwald Sababurg. The concept for the board game, Enchanted Forest, was developed from the castle.
