European herring gull
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, including Black-headed gull, Pomeranian duck, European herring gull, Grey heron and Mute swan. 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.
