The Estonian maritime museum is located on two sites. Part of the collection is on display in Thick Margareta, a tower in the city wall encircling the old town, while the rest can be found in Lennusadam (an old water plane hangar). Both sites are a walking distance apart. This museum does not really offer much in diving history, but a few very interesting artifacts can be found in Thick Margareta. These alone warrant a visit.
