The museum focuses on the all-important sea-faring aspect of Estonia’s history, displaying such things as Neolithic fishing gear, antique diving equipment, and even the entire wheelhouse from a 1950s-era trawler. The extensive museum covers four floors of the historic Fat Margaret’s cannon tower. 

This fat, sturdy defence tower was built from 1511 to 1530 to protect Tallinn from attacks by the sea, but it was also part of the older Great Coastal Gate, now the town’s last intact outer gate. 

Take the stairs to the roof-top for a picture-postcard view of the Tallinn harbour and the Old Town.

Entrance with Tallinn Card is free.
