A purposeless walk through the old town to the 900-year-old St. Peter's Basilica. The cantonal flag of Geneva, Switzerland, has an eagle and key pattern, and the black eagle on the left symbolizes the Holy Roman Empire. Geneva was once a free city of the Holy Roman Empire, a city with a certain self-regime and directly under the authority of the Emperor of the Shinto (not the lord); the key on the right symbolizes St. Peter. Geneva was once the seat of the Pope. Today, St. Peter's Basilica in the old town is a great place to climb up and overlook the panoramic view of Geneva.
