The Gros-Horloge is a famous medieval astronomical clock located in the heart of Rouen. As one of the city's main symbols and an outstanding monument of Gothic architecture, it attracts tourists from all over the world. The clock is built into an elegant Renaissance arch spanning a busy pedestrian street, creating one of the most photographed views in France.

The uniqueness of the Gros-Horloge lies not only in its venerable age but also in its complex construction. It is one of the oldest double-sided clocks in Europe, with a mechanism dating back to the 14th century. The richly decorated dial, 2.5 meters in diameter, is a true work of art. A golden sun with 24 rays shines in the center, while the single hour hand is tipped with a figure of a lamb—a tribute to the wool industry, which was historically the foundation of Rouen's prosperity.
Beyond the time, the clock displays other fascinating information. Above the dial is a silver sphere that rotates to show the phases of the moon. In a special window at the base of the dial, allegorical images of deities representing the days of the week change daily. The entire complex includes not just the clock and the arch, but also the adjacent Gothic belfry, which visitors can climb to enjoy a panoramic view of the old town.
