Dronningholm Slot

Dronningholm is a castle ruin in Halsnæs Municipality standing on elevated ground with views over the area between Auderød and Brederød. The remains show the foundation and walls of a medieval fortress located near the large Arresø lake.

King Valdemar the Great ordered the castle built in the 12th century and his son Valdemar Victory completed it around 1200. The fortress served as an important administrative center in the region during that period.

The ruins hold protected monument status in Denmark and display medieval stonework techniques. Visitors can observe the distinctive foundation layout and defensive building features that reveal how people lived in the 12th century.

The site is accessible around the clock throughout the year with no advance booking needed. Visitors should wear sturdy footwear as the ground is uneven and the ruins involve exposed stones and elevated passages.

Boats could once sail directly to the fortress across Arresø lake even though the lake had no natural connection to the sea. This made the castle strategically valuable for water-based trade and defense.
