Lennusadam, literally "air port", was constructed in 1916 for the purpose of serving the seaplane fleet with a spectacular, three-domed concrete hangar. Today, it serves as an outpost of the Maritime museum, serving its large collection of complete ships, airplanes and maritime and military equipment too large to fit the Fat Margaret. Inside the hangar, the highlight is the complete submarine Lembit, whose interior can be visited as well, a shipwreck from the 16th century and a collection of smaller boats and seaplanes. The crown of the colleciton moored outside in the harbour is the steam-powered icebreaker Suur Tõll. Throughout the museum, a number of state-of-the-art technologies and solutions are employed for a more engaging and enjoyable visit, and the museum has a wide range of activities and tours on offer. As the Seaplane Harbour is a bit out of the way, those getting peckish can enjoy a meal at the museum's restaurant Maru inside the hangars.
