Gros Horloge (Great Clock), Rouen (must see)

Dating back to the late 14th century, the Great Clock has become a symbol of the city's rich heritage. As you approach the clock, you'll be captivated by the ornate arch and the beautifully carved wooden belfry.

Originally constructed without a dial, this extraordinary timekeeping mechanism showcased a unique design where one revolution of the hour-hand represented a full twenty-four hours. Crafted from wrought iron, the clock's movement is a monumental piece of craftsmanship, renowned for its size and complexity. In fact, it's considered one of the largest surviving clock mechanisms in existence, dwarfing even the renowned Wells Cathedral clock.

Another fascinating feature of the Great Clock is its depiction of the days of the week, each accompanied by allegorical symbols. These representations provide a unique insight into the cultural and symbolic significance attached to each day.

The clock facade is a work of art in itself, featuring a golden sun with 24 rays set against a starry blue background. The dial of the clock is equally captivating, measuring an impressive 2.5 meters (250 cm) in diameter. Within the dial, one can observe the phases of the moon displayed in the oculus of the upper part, completing a full rotation over 29 days.

While the clock's original movement is no longer functional, it continues to captivate visitors with its historical significance and artistic beauty. What makes the Great Clock even more fascinating is its multifaceted history. Originally, it served as a city gate, controlling access to the medieval town. Over time, it evolved into a symbol of municipal authority and civic pride.
