Few fortresses hold the power to amaze and impress quite like Copenhagen’s Kastellet. This stunning five-pointed structure was built in 1662 and houses one of the most incredible examples of this style of architecture in the country. Travelers who venture into the emerald grounds will find well-preserved barracks, a small chapel and even a moat. And while the grounds are lovely to explore, visitors say views of the iconic Little Mermaid, Marmorkirken and the cobalt-colored harbor add another level of beauty to this landmark that’s worthy of the journey. Travelers will likely find tourists and locals biking, walking and picnicking at this scenic destination.
Kastellet is open daily from 10 a.m. until 6 p.m. It is accessible by taking the 1A bus or the local Nordre Toldbod ferry. Entrance is free to the public.
