Established in 1680 when Sweden was a great military power, Karlskrona was founded as a naval port, and the city’s rich maritime and architectural heritage have earned it the designation of UNESCO World Heritage Site. Many Baroque buildings remain intact, such as those on the grand main square, Stortorget. Having protected the harbor for more than three centuries, Kungsholm Fortress and Drottningskär Citadel reveal a remarkable history. In the fascinating Marine Museum, explore a Soviet submarine, inspect a World War II minesweeper, and observe an 18th century shipwreck through an underwater tunnel.
