Peter the Great's Naval Fortress museum

The Lennusadam naval museum is located in the Tallinn aeroplane harbour, in a building originally constructed as a hangar for seaplanes in the area of Peter the Great's Naval Fortress. The hall has an area of 8,000 m2 (86,000 sq ft) and was put out of service during the Soviet era. 

The space has a lot of history as well as a fascinating, dense acoustic - here we tour the space via elevated walkways, periodically listening in to "acoustic posts" with interviews about naval life, and the drone of a huge fan designed to show visitors the physics of engine function.
