Wilhelmsthal Castle was built between 1743 and 1761 as a summer pleasure palace for Landgrave Wilhelm VIII and is considered one of Germany's most important Rococo castles. Particularly well-known are the magnificent Rococo interiors and the extensive castle park with water features. Today, the castle ensemble is one of the most important cultural monuments in North Hesse, and you can visit it as part of guided tours.

It can no longer be clearly determined when the wooden palisade castle was built. It probably already served Charlemagne and his troops in the Saxon Wars (772 to 804) as a strategic outpost to secure the Frankish Empire. Several drawings[2] that are on a sign near the former castle indicate that the Igelsburg probably cannot be classified as a classic castle complex. Because within four ring walls, some of which can still be seen today, four houses can be seen on this sketch, two of them on the summit, the other two a little further down. Historians suspect that the barons of Dörnberg, first mentioned in 1100 in the Habichtswald area, had their seat in the castle. The wooden houses of the Igelsburg probably fell into disrepair as early as the 12th or 13th century. Source: https://de.wikipedia.org/wiki/Burruine_Igelsburg
