Kastellet

Kastellet is one of the best preserved fortresses in Northern Europe, built in 1662. This pentagonal, star-shaped structure conceals Denmark's fascinating military history.

As you stroll along the ramparts, you can admire the 1704 Baroque Citadel Church and the historic windmill from 1847 - one of the last working windmills on the ramparts of Copenhagen.

It's a place where history meets tranquility - perfect for both lovers of military architecture and those looking for a picturesque place to relax overlooking Copenhagen harbor.
