For many Finns, Naantali (Swedish: Nådendal) means Moomins. Most visitors are day trippers from Turku, just 18km away, but some come from Sweden for a day out at the theme park or to wander the quaint Old Town. Even the president spends her time off here, leading many to call it the summer capital of Finland. Out of season Muumimaailma (Moomin World) closes its gates, and the Old Town acquires the melancholic air of an abandoned film set. But Naantali continues to work hard behind the scenes, with Finland’s third most-trafficked port, an oil refinery and an electricity power plant.
