Hohensalzburg Castle is one of the best places to see the wonderful countryside landscapes of Salzburg. Built by order of the Prince Archbishop of Salzburg, it is 250 meters long and 150 meters wide, and is one of the largest medieval castles in Europe. Stunning mountains and forests surround the hilltop Baroque tower. The castle itself is also a great historical building, and a great place to put it on the itinerary of your tour in Salzburg.
