The back side of the clock tower in Place de l’Hotel de Ville, Aix-en-Provence, France. Located next to the City Hall, the tower was built in 1510. It is topped with a 16th century wrought iron cage that houses a bell, which still rings the hours of the day. White limestone blocks from a Roman era structure were support the base of the tower. Facing away from the plaza, this clock face is simple and utilitarian. The front of the clock tower (oops, I missed getting that shot) is much more ornate and includes a 17th century astronomical clock and an 18th century urn commemorating the spirits of those who died in the French Revolution.
