Why Go
Fat Margaret is one of those Tallinn landmarks you’ll likely notice even if you don’t plan for it. Visiting turns a “nice tower photo” into a real story about Tallinn as a harbor city.
How to Build a Maritime Day
If you want one themed day outside the Old Town loop:
- Start here for harbor-facing history
- Then go big with Seaplane Harbour
- Finish with a sunset walk in Noblessner

Pair It With
- Balti Jaam Market for a local-feeling lunch
- A coastal mood walk (see Sea & Modern Tallinn)
Practical Notes
Harbor-area museums can have seasonal schedules and special events. Check the official Maritime Museum site for the most current visit details.
The Tower at the Coastal Gate
Fat Margaret (Paks Margareeta in Estonian) is a huge, squat cannon tower built in the 16th century to guard the Great Coastal Gate — the main entrance into the Old Town from the sea. Its enormously thick walls were designed to impress arriving ships and to withstand cannon fire, and they still do the first job today: anyone walking up from the port passes beneath it.
The nickname is part of local lore, and the tower has had a varied life — including a stint as a prison — before its present role. Today it houses the Estonian Maritime Museum, which turns a striking piece of fortification into a window onto Tallinn’s identity as a seafaring, trading city on the Baltic.
Visiting therefore does two things at once: it lets you experience one of the city’s most powerful surviving towers from the inside and out, and it tells the broader story of Estonia’s relationship with the sea — shipping, navigation, fishing and naval history.
What You’ll See
A visit combines the building with maritime exhibits and a fine rooftop view:
- Estonian Maritime Museum exhibits on seafaring, navigation, shipbuilding and harbour history, spread through the tower’s floors.
- The massive tower interior itself, with its remarkably thick defensive walls.
- A rooftop viewing terrace looking out over the harbour, the coastline and the Old Town rooftops.
- The neighbouring Great Coastal Gate, the historic sea entrance to the city.
It is the natural city-side companion to the much larger Seaplane Harbour maritime museum a little further along the coast.

Who It Suits
Fat Margaret suits history lovers, families and anyone interested in Tallinn as a harbour city rather than only a medieval one — and the rooftop terrace makes it a winner for view-seekers and photographers too. Because it is right at the edge of the Old Town on the way to and from the cruise port, it is also a convenient stop for arriving or departing ferry and cruise passengers.
It works best as the opening chapter of a maritime day: start here for the harbour-facing history, continue to the Seaplane Harbour, and finish with a sunset walk in Noblessner, with a local-feeling lunch at Balti Jaam Market along the way.
Even if you only have a short window — between checking out of a hotel and boarding a ferry, say — Fat Margaret is an easy, rewarding stop right on the path between the Old Town and the port, combining a slice of history with a fine rooftop view of the harbour you are about to sail from.

FAQ
What is Fat Margaret in Tallinn?
Fat Margaret (Paks Margareeta) is a large 16th-century cannon tower at the Great Coastal Gate, the historic sea entrance to Tallinn’s Old Town. With its enormously thick walls, it once guarded the harbour and today houses the Estonian Maritime Museum.
What is inside Fat Margaret?
It houses the Estonian Maritime Museum, with exhibits on seafaring, navigation, shipbuilding and harbour history across the tower’s floors, plus a rooftop viewing terrace overlooking the harbour and Old Town rooftops.
How is Fat Margaret different from the Seaplane Harbour?
Both are part of the Estonian Maritime Museum, but Fat Margaret is the compact city-side tower at the Old Town’s coastal gate, while the Seaplane Harbour is a much larger museum in spectacular seaplane hangars further along the coast. They pair well for a full maritime day.
Is Fat Margaret worth visiting?
Yes, especially if you are interested in Tallinn’s harbour history or want a rooftop view of the coast and Old Town. Its location at the edge of the Old Town on the way to the port also makes it convenient for cruise and ferry passengers.
