Built on 14 islands, Stockholm is a fascinating, compact city. The Old Town, Gamla Stan, is a warren of narrow streets with 750 years of history. Fast- forward and trendsetting island Södermalm is a hotbed of fashion, youth culture and entertainment. A National City Park, leafy Djurgården is a short walk from the inner city. The Nobel Prize's hometown offers sites from the Vasa Museum, with its 1628 warship, to Skansen Open-Air Museum, where a zoo, festivals and 150 historic buildings inform and entertain.
