View of St. Paul's Tower, Le Château D'Annecy
St. Paul's Tower was built in the same period as St. Peter's Tower (1380-1393). It is mentioned in 1380. It took on the name Mirror Tower after being called the Emion Tower, presumably after the Genevois family that owned the land it was bilt on. It was not until the 18th century that it became known as St. Paul's Tower. This tower, along with St. Peter's Tower, provided support for the ramparts, which were existent in 1430 and remained until the early 16th century.
From here, you can visit St. Peter's Tower, go around to the main gate, or go inside to the courtyard.
