Levyhalli is located on Susisaari Island in Suomenlinna, at the entrance to Artillery Bay. The building was constructed in 1917 on the site of the former galley shipyard’s repair basin and was originally used as a pumping station, boiler house and workshop facilities for the Suomenlinna dry dock. Levyhalli has largely retained its original appearance; the most significant alterations concern the roof lanterns, which were most likely renewed in 1928.

During the early years of Finland’s independence, the building came under the authority of the Suomenlinna Technical Administration’s workshop and was used for the maintenance of motor vessels. From 1921 onwards, the premises housed the Finnish Air Force aircraft factory, and the hall was converted into an aircraft assembly facility. Aircraft production continued in Levyhalli until 1935.

In 1936, the building was transferred to the State Shipyard and later to Valmet Ltd, remaining in industrial use until 1985. The machinery preserved in Levyhalli dates back to Valmet’s period of operation. Today, Levyhalli serves as an exhibition venue during the summer season.
