Canton Aargau sits at the heart of Switzerland where water rules the landscape. Three great rivers – the Aare, Reuss, and Limmat – converge near Brugg, earning the spot the nickname 'Water Castle of Switzerland.' To the north, the Rhine forms the border with Germany. Rolling hills, fertile farmland, and scattered forests round out a canton that is perfectly placed at the crossroads of northern Switzerland.
