The Greek state, wishing to honour all those who fought for the freedom of our country, decided in 1964 to establish a War Museum. The Museum was inaugurated in July 1975 and is still in operation today. Its mission is the collection, preservation and exhibition of war relics, the study, documentation and promotion of the struggles of the Greek nation from antiquity to the present day, in order to stimulate national memory and promote the historical continuity and unity of Hellenism.

Nowadays, the War Museum is the largest museum of military history in Greece and one of the largest in Southeastern Europe. In its premises, relics relating to the history of the Greeks from all war periods are exhibited, while there are also sections of historical, photographic and film archives.
