Dillenburger Schloss

Dillenburg Castle stands on a hill above the Dill river in the town of Dillenburg, 25 miles northwest of Gießen. The hill rises 958 feet above the river and has been a site of fortifications since the 13th century. Count Henry the Rich of Nassau founded the castle around 1240, and it later became the birthplace of Prince William of Orange in 1533. The original wooden fortifications were replaced by stone structures in the 17th century. A fire from cannon damage during the Seven Years’ War in 1760 destroyed the main building, leaving only ruins today. The castle’s history is tied to the Protestant Reformation and the rise of William the Silent. Below the hill, the town’s Evangelical church, originally built in 1491 as Johanniskirche, holds the vault of the princes of Nassau-Dillenburg. The church reflects the religious changes of the 16th century, when the Reformation reshaped the region. William the Silent planned his rebellion against Spanish rule from this area, marking a key moment in Dutch history. A visitor to Dillenburg finds the Wilhelmsturm, a 19th-century lookout tower funded by Princess Marianne. The tower serves as a landmark and houses the Oranje-Nassaumuseum, which tells the story of William the Silent and his role in Dutch independence. The hill offers views over the town and the Dill valley, while the ruins of the old fortifications recall the castle’s military past. The area is part of the Orange Route and Rothaarsteig, linking it to broader historical and hiking trails. The town below blends modern life with centuries of tradition.
