Turku is one of the most important historical centres of Finland and also one of its busiest seaports. The Archipelago is a unique travel destination situated in the island area. Here you have the chance to enjoy complete peace and relaxation or engaging yourself in many activities. There are several historical museums that display the city's medieval period, such as the Turku Castle, which has been a functional historical museum since 1881, and the Aboa Vetus museum, built in the late 1990s over the 14th century archaeological site. The Luostarinmaki handicrafts museum was the first Scandinavian venue to receive the "Golden Apple" tourism award. The Abo Akademi University hosts the Sibelius museum - the only music museum in Finland. Turku is also the official Christmas city of Finland.
