The world’s oldest restaurant can still be found housed within its original structure in St. Peter’s Abbey in Salzburg. While no one knows exactly when it first opened, 803 is the year usually cited, as that’s when the first mention of it appears in print, in the work of the scholar and monk Albuin, who was a devout follower of Charlemagne. Both Wolfgang Amadeus Mozart and Christopher Columbus are said to have been served at the restaurant.
