The most important exhibits are the weaponry, the uniforms, the memorabilia, and the personal effects of the leaders of the Macedonian Struggle (1904–8), numerous other uniforms, and a collection of 1,350 contemporary photographs. There are also explanatory maps, books, newspapers, and paintings of the Macedonian landscape in the late 19th and early 20th century. The exhibits occupy seven rooms and are grouped as follows: Macedonia before the outbreak of the Struggle; the struggle in western Macedonia; the consulate and the organization of Thessaloniki; the office of the consul Lambros Koromilas; the role of the people of Macedonia in the Struggle; the Struggle in central and eastern Macedonia; the Struggle in the Yannitsa marshes; and the events in Macedonia after the end of the Struggle and the Young Turks revolution.
In the basement there are life-size dioramas of scenes from the Struggle: a school at the beginning of the 20th century; the Patriarchists struggle to preserve their churches from the assaults of the Exarchists; the action of Greek corps on Yannitsa lake; and the arrival of a spy in Florina. On the first floor there is an audio-visual system with films relating to the history of Macedonia.
The museum offers the public guided tours (booked in advance) and educational games. There is also a lending department for photographic displays and video films. The research center has put together abundant archival material from the period 1870–1912 on microfilm and databases on the local history of Macedonia.
