Gamla Stan is the oldest part of the city - the name means "Old Town", and is usually called that in English. Djurgården is mostly a large park, but there are buildings on the island. Most of these are museums that commemorate Sweden's and Stockholm's past - like Skansen, a zoo with a Swedish theme. Skeppsholmen is an island that used to be a training ground and military school, but most of the buildings are now used for museums and art galleries, such as the Modern Museum, or the East Asian museum. Riddarholmen is a part of Gamla Stan, but actually a different island.
