Salzburg = Salz + burg. Quite literally, salt castle. Salzburg may be famous for it's starring role in the Sound of Music, but it has a long, long, long history with salt, salt mining, and it was the profits from the salt mining that financed the building of the city. Now, you may know that Aaron and I are never ones to pass up a mine tour, and we knew that this was one thing we had to do on our weekend getaway to Austria.
