Built in 1077, Hohensalzburg Fortress that stands on the hillside of Salzburg. It is one of the largest medieval castles in Europe and is the largest preserved fortress in Europe today.
There were two options to get to the top - take the funicular or walk. We chose to walk. At one point we calculated the grade up to be 11%. The kids were troopers. I looked back and Michaela was doing lunges up the climb. That really didn't surprise anyone!
