Harbours

Mariehamn lies on a peninsula with two main harbours, west and east. Both remain ice-free for most of the year and experience minimal tidal variation.
The Western Harbour is an international port with daily ferry connections to Sweden, Estonia, and mainland Finland. Because Åland is outside the EU customs zone, ferries call at Mariehamn to enable duty-free sales.
The city has a long maritime tradition. The four-masted barque Pommern, now part of the Åland Maritime Museum, is moored in the Western Harbour. The Eastern Harbour hosts one of the largest marinas in Scandinavia and the historic Dutch steamer F.P. von Knorring, named after Åland teacher and vicar Frans Peter von Knorring.
