Seaplane Harbour Marina (Sihtasutus Eesti Meremuuseum)

This marina sits right next to one of Tallinn's most fascinating spots — the Estonian Maritime Museum, housed in century-old seaplane hangars with nearly 200 exhibits on Estonia's seafaring history. You're just a short walk from Tallinn's Old Town, so the city is genuinely on your doorstep. The industrial-heritage atmosphere of the harbour gives it a character unlike most marinas, blending working waterfront with serious cultural weight.
