The town has a tradition of regarding itself the capital of (the south-west part of) the archipelago. There is a wooden old town, a giant limestone quarry by the centre (origin of Nordkalk Corporation and its siblings), industry and rural country-side. Much of the central and most of the outer archipelago and thus most of the Archipelago Sea National Park belongs to Pargas. Pargas consists of the former municipalities Pargas, Nagu, Korpo, Houtskär and Iniö.
Pargas is in a traditionally Swedish speaking area. Because of the industry (later: proximity to Turku) there are nearly as many Finnish speaking in the town, though. The municipality is officially bilingual and you get service in both languages nearly everywhere.
As in the rest of Finland you get along in English with most people.
