Waldenburg stands in Attendorn (Kreis Olpe), in North Rhine-Westphalia, Germany. The building is a listed Baudenkmal. No visits are on record for this building.

The Waldenburg is the ruined hilltop castle overlooking the Biggetalsperre reservoir, near Attendorn in the Sauerland region. Built no later than the 10th century, it is considered the oldest known structure in the Kreis Olpe and the historic origin of local self-government in the area. Only fragments of the stronghold remain, set on a rocky spur once defended by three successive ditches. The site now lies within a protected nature reserve, where the earthworks and building traces still convey the scale of the former fortress.

What to know

  • The ruin stands on a rocky spur at 370 metres, with steep drops on three sides, so visitors should expect uneven terrain and some walking.
  • The Waldenburg is listed as a Baudenkmal in North Rhine-Westphalia.
  • The site lies within a designated nature reserve, so staying on marked paths is advisable.
  • No opening hours, admission fees or accessibility features are published, as this is a freely accessible outdoor ruin.
  • Its location next to the Biggetalsperre reservoir makes it easy to combine with a lakeside walk.
