Burg Sonnenberg

Burg Sonnenberg is a castle ruin on a mountain spur with preserved fortifications, city walls, and a prominent tower overlooking the Rambach valley. The site displays the typical layout of a hilltop fortress with steep approaches and defensive structures that define the landscape.

The castle was founded between 1201 and 1203 by Henry II and Robert IV of Nassau to protect Wiesbaden against the Lords of Eppstein in border disputes. It came under the rule of Count Adolf of Nassau, who later became King of the Romans.

The tower houses exhibits from the medieval period when Nassau ruled the region. Visitors can learn about this era and its significance to local history while walking through the site.

You can reach the castle grounds through marked paths from Sonnenberg's center, though access to some areas is steep and not wheelchair accessible. Sturdy shoes are recommended since the paths are uneven and the slopes are considerable.

The castle played a central role in the life of Count Adolf of Nassau, who began his rise to become King of the Romans in 1292 from this location. This brief royal episode gives the site special historical resonance for those interested in regional power and medieval advancement.
