The historic half-timbered town on the Dill

The Oranien City of Dillenburg is the birthplace of the Dutch royal family. The Wilhelmsturm, the city's iconic landmark, was built in honor of William I of Orange, who was born here in 1533. The underground defense system (casemates) of the former castle ranks among the largest early modern defense structures in Western Europe. Alongside the historic old town with its picturesque half-timbered houses and winding alleys, Dillenburg offers numerous attractions as well as a diverse range of hiking and cycling routes, including the famous Rothaarsteig.
