The Manege Military Museum, located in Suomenlinna sea fortress, is originally a Russian artillery storage built in 1880-1881. In 2012 a new exhibition From Autonomy to Atalanta was opened in the Manege. The new exhibition covers Finnish military history from early 19th century to the present day. Although most of the exhibition consists of World War II history, there is also some information about earlier centuries. In 2018 a new exhibition "Finnish Defence Forces - 100 years at war and peace" was opened in the Manege.
The building was opened as a museum in 1989 and there are approximately 40 000 visitors annually from all over the world. The museum is open 9.5.2018–30.9.2019 every day 11AM-6PM.
