Stockholm

Stockholm, the capital of Sweden, encompasses 14 islands and more than 50 bridges in a vast archipelago of the Baltic Sea. The cobblestone streets and ocher-colored buildings of Gamla Stan (the old town) are home to Stockholm's 13th-century St. Nicholas Cathedral, the Kungliga Slottet royal palace, and the Nobel Museum, which focuses on the Nobel Prize. Ferries and tour boats carry passengers between the islands.
