Sited within Finland's sixth largest city, the port principally handles traffic between Turku and the Swedish capital of Stockholm and the enclaved Åland.
The port spans a wide area on the southern coastline of the city of Turku, from the mouth of the River Aura to the district of Pansio.
The port is mentioned in the Arab geographer Muhammad al-Idrisi's 1154 book Kitab Rudjdjar, reflecting Turku's status as a capital city and major Baltic Sea trading post.
Turku Harbour railway station is located adjacent to the main passenger-ferry berths used by the ferries to Stockholm in Sweden and has two full-length tracks arranged with a central platform between them.
The phrase Turku Harbour is the semi-official English name of the railway station, being used in English-language timetables and "next stop" announcements on board VR trains.
