The history of the Mannerheim Museum since 1951 has seen a wide range of perspectives on Marshal's life. During the time of the first curator, O.R. Bäckman, cards of condolences and wreath ribbons were put on display, among other things. The layout of the actual home for the public to see had also required an arrangement and the exclusion of the former resident's most private belongings was necessary. Key to this work were two housekeepers.
The actual themed exhibitions only began to be created later as the exhibition activity became more scientific and with the re-arrangement of the second-floor showrooms in the 1970’s. Over the years, exhibitions have presented an insight to e.g. Mannerheim’s expeditions, wars, residences, horses and cars. Themes related to his Asian expedition have been especially often on show.
The museum has since 2013 especially created special exhibitions at quite a dense pace. Exhibition policy has shifted from memorial exhibitions and key stages in Mannerheim’s life, to a more thematic and problematizing direction. At the same time, the museum has not only tried to emphasise the most serious subjects and the lighter themes, but also the social and cultural dimensions that can be found in the life of the museum's target person and in a limited space present them as small studies utilizing original material and contextualizing.
The exhibition working groups have balanced between civilian and military as well as national and international themes and therefore engaged more of the personnel and worked together with a number of different cooperating entities. In 2016 an exhibition designed in cooperation with students from the University of Helsinki was built for the first time, an exhibition which adopted an outside point of view on Mannerheim.
Events such as salons, special guided tours and debates have been organised linked to the special exhibitions. Creating exhibitions abroad has continued lately with different associates and in collaboration with other museums, a tradition which started in the 1990s.
