Berchtesgaden
Berchtesgaden is a German town in the Bavarian Alps on the Austrian border. South of town, Hitler’s Eagle’s Nest retreat, the Kehlsteinhaus, has a restaurant with alpine views. The Dokumentation Obersalzberg museum chronicles the Nazi era. Salzbergwerk Berchtesgaden illuminates the salt mine’s 500-year history. Lifts lead to Obersalzberg and Rossfeld ski areas. To the south, trails cross Berchtesgaden National Park.
Copenhagen
Copenhagen, Denmark’s capital, sits on the coastal islands of Zealand and Amager. It’s linked to Malmo in southern Sweden by the Öresund Bridge. Indre By, the city's historic center, contains Frederiksstaden, an 18th-century rococo district, home to the royal family’s Amalienborg Palace. Nearby is Christiansborg Palace and the Renaissance-era Rosenborg Castle, surrounded by gardens and home to the crown jewels.
Venice
Venice, the capital of northern Italy’s Veneto region, is built on more than 100 small islands in a lagoon in the Adriatic Sea. It has no roads, just canals – including the Grand Canal thoroughfare – lined with Renaissance and Gothic palaces. The central square, Piazza San Marco, contains St. Mark’s Basilica, which is tiled with Byzantine mosaics, and the Campanile bell tower offering views of the city’s red roofs.
Reykjavik
Reykjavik, on the coast of Iceland, is the country's capital and largest city. It's home to the National and Saga museums, tracing Iceland’s Viking history. The striking concrete Hallgrimskirkja church and rotating Perlan glass dome offer sweeping views of the sea and nearby hills. Exemplifying the island’s volcanic activity is the geothermal Blue Lagoon spa, near the village of Grindavik.
