My favorite part of this is how the water is shaped into a star! Again, just happened to stumble upon the after visiting the little Mermaid.
This attraction makes for a beautiful leisurely walk taking in the sights of 8 other attractions. It’s a surprisingly short walk along the water! I think it’s the perfect spot for a tourist in a rush– just follow the track and you’ll hit up the hotspots!
I almost wish some of the signage was in English or at least provided better direction (check my reviews, I’ve ‘stumbled’ upon the vast majority of them) but in this instance I’ve not been lost once and the sense of discovery has fed my adventurous spirit.
I plan on returning tomorrow because its just a fun walk but will walk I’m a different direction just to see where I end up.
Definitely worth checking out if you’re in Copenhagen!

Un gran parque en forma de estrella, que es un fuerte militar abierto al público pero que te encuentras con algún militar haciendo su recorrido de guía. También a daneses haciendo footing.

The castle area itself isn’t the most impressive, but since it’s near the Little a Mermaid statue, it’s worth taking a look. I wouldn’t go out of my way to come here, but if you’re in the area or if it’s on your way to somewhere else, make a stop!

I saw a lot of tour buses pulling in to Kastellet just to see the Little Mermaid statue, which made me sad because the «island» is a beautiful, calm place to spend an afternoon in its own right.
There are a lot of hidden gems around Kastellet, including a windmill, a quaint little stone church, a beautiful fountain depicting the founding myth of Denmark, and a moving monument to Danish soldiers killed in peacekeeping missions. While you’re exploring I would definitely recommend stopping at the ice cream stand to purchase a soft ice dipped in cocoa – the best bite I had in Denmark!
My only complaint is that there could be better signage; since it is a fortress, after all, there’s only one way to get in and out of it, so I spent about 30 minutes wandering around lost. At least I had the ice cream to fortify me!

This places got my attention because of its pentagram form. It used to be a fortress but now it is very cool park. It is really nice just to walk around the places and check how a fortress looks like.
On the east side you will find a beautiful windmill.
There is also a church on the grounds. There is a changing of the guard ceremony at the Central Guard House every day at 12.00, don’t miss it! =)

A wonderful place for taking a walk, especially if you like old fortresses and the weather is fine.
There is also a monument for the fallen Danish soldiers (during peacekeeping missions). It’s quite new — built in 2011.

We were walking to The Little Mermaid and passed by here. It was quite a trek but we saw beautiful things along the way. There was a windmill, a gate, cannons and sculptures. This was an old fort.
There’s a church next to Gefion Fountain. I wouldn’t recommend walking to The Little Mermaid like we did if you have time restraints or you don’t like walking too much.

Walking in, it was hard to believe that this was a military fortress. It just seemed like a little village or something. But goodness, was it ever lovely! It’s so nice to just sit down on one of the benches near the church and read. Or wander around to see the various buildings.

An sich ein schönes abgetrenntes Gelände. Jedoch nicht sehr groß, aber sollte man gesehen haben. Zudem gibt es ein interessantes Museum auf dem Gelände.

A very cool old fort area, whose grounds are shaped in a large star. This is right next to Gronbech and Churchill where we had lunch. We walked the old stones and bridges and also caught some of the military personnel moving in and out. It also borders Churchill Park and is a hop away from the Little Mermaid statue by the water. If you’re in the area dont miss out, it’s a cool preservation of Danish military history

Das Kastellet war für mich eher enttäuschend — nichts Besonderes, wenn ihr mich fragt.
Beeindruckt war ich zuvor von dem symmetrisch angelegten Fort, aber es ist auch heutzutage immer noch in Armeehand und Kasernen — wenn auch historische — gibt es zuhauf.
Eintritt kostet der Besuch nichts — auch mal was!
Also besucht haben muß man das Kastellet nicht unbedingt — es fehlt dann nichts an Kopenhagen-Know How.

Great to see how an old fort is constructed. The star shape island was constructed in the late 1600s and is WELL preserved. You can really see how it was used and defended in the past. There is a memorial inside and it’s a very relaxing area to spend the afternoon. It currently acts as a public park as well as housing military. Definitely a great place to stop by and

Wunderschön im Winter. Man kann auf den ehemaligen Befestigungswällen spazieren gehen und zahlreiche antike Kanonen, sowie eine Windmühle bewundern.

Bei schönem Wetter ist es hier sicher traumhaft schön! Wir haben leider einen verregneten, grauen Tag erwischt, so dass wir die schönen Parkanlagen und die Natur rund um das Kastellet gar nicht genießen konnten. Aber wer gerne die Natur genießt, der ist hier richtig aufgehoben.

This former citadel is now a quiet spot for a walk or a jog along the fortification walls. Because it’s so close to the Little Mermaid statue, it’s a nice way to return to the east end of the city if you’re making a walking tour of the sites.
