St. Bernards
High in the Alps near the border between Italy and Switzerland is the Great St. Bernard Pass, used by humans to cross the mountain range since the Bronze Age. As they headed north to conquer somebody or other, the Romans erected a temple to Jupiter there. In 1049, Bernard of Menthon (canonized St. Bernard in 1923) built a hospice on top of the temple ruins as a shelter for travelers.
