Kastellet, located in Copenhagen, Denmark is one of the best preserved fortifications in Northern Europe. It is constructed in the form of a pentagram with bastions at its corners. Kastellet was continuous with the ring of bastioned ramparts which used to encircle Copenhagen but of which only the ramparts themselves Christianshavn remain today.
A number of buildings are located within the grounds of Kastellet, including a church, as well as a windmill. The area houses various military activities but its mainly serves as a public park and a historic site.
In spite of the continuous military presence in the area, the Citadel is today a peaceful, protected area, serving as a public park as well as a cultural-historical monument. It is located close to Langelinie, The Little Mermaid, the Gefion Fountain. It is a popular place to go for a walk on a sunny day, and is very popular with children on account of the many animals and birds in the grounds. The site includes two small museums with limited opening hours. The Garrison’s Historical Collections are on display in one of the guard buildings inside the North Gate. The other is the Livjæger Museum
