Turku Finland, located on the southwestern coast of the country, dates back to the 13th century. It is known for Turku Castle, a medieval fortress with a history museum. It is Finland’s fifth-largest city, the largest winter port, home to naval shipyards, and industries including sugar refining, steel, electronics, lumber, flour, pottery, and textiles. Restaurants line the cobbled riverside streets and on the eastern bank lies the Old Great Square. The ancient Turku cathedral in the heart of the city also dates back to the 13th century.
