Located in the heart of Calais, the World War II Museum (Musée Mémoire 39-45) is a unique historical space. Its main feature is its location within an authentic German naval bunker built during the war. This massive fortification serves as an important exhibit in its own right, vividly demonstrating the power of military architecture from that era.

The museum's exhibition in France offers a deep dive into the events of 1939–1945, focusing on life in the region during the occupation and liberation. Inside the bunker, visitors will find meticulously recreated interiors: from radio stations and command offices to living quarters with bunk beds. Personal belongings of soldiers, original documents, and uniforms create an immersive atmosphere and help visitors better understand the daily reality of those years.
The museum is popular with tourists thanks to its authenticity and extensive collection. In addition to the indoor galleries, the outdoor area is of great interest, featuring displays of heavy machinery and defensive structures. Situated in the picturesque Parc Saint Pierre, the museum is a must-visit for anyone interested in military history who wants to see the heritage of the past in its original form.
