Vasterås is located in central Sweden along the shores of Lake Mälaren and is one of the oldest cities in the country, dating back to medieval times. This is the home of Sweden's largest inland harbour as well as the country's largest Viking burial mound. There is plenty to see and do here with interesting architecture to explore, a variety of museums, including the Vallby Open Air Museum, and even an 8 floor water park for those looking for a little adrenaline.
