An artillery tower with walls five metres thick at the sea gate: Fat Margaret was built between 1511 and 1531 to guard Tallinn's entrance from the sea — twenty-five metres across with walls among the heaviest in northern Europe, and from that bulk came the popular name. It served as an arsenal, then a prison in the nineteenth century, was burned in the revolution of 1917 and stood ruined for decades. Restored and reopened in 2019 as a branch of the Estonian Maritime Museum, its display is entirely modern: Estonia's history by sea from Viking ships to the Hanseatic League to today's ferries, with interactive screens and boats hung in the tower's void. Its roof is a terrace over the harbour and the old town's roofs, and beside it stand the Great Coastal Gate and the memorial to the ferry Estonia, which sank in 1994 — postwar Europe's worst maritime disaster. Combine it with the Seaplane Harbour on a joint ticket.
