Much like Bruges, Salzburg is a compact city you can explore on foot, and there's definitely plenty to take in. It has all the museums you could wish for, including one dedicated to Mozart, located at his birthplace. The city's also home to some incredible historical architecture, including Hohensalzburg Fortress, the biggest fully preserved castle in Central Europe. The city's squares and gardens are worth exploring too, as they change dramatically with the seasons. Rest assured, you definitely won't be the only one singing songs from The Sound of Music as you tour this beautiful city.
