The clock mechanism, originally installed in 1498, is one of the oldest still functioning in France.
The tower was repurposed as a prison during the French Revolution.
The bronze bell within the tower, nicknamed 'la duchesse', was cast in the 16th century.
The tower architecture reflects the transition between late Gothic and early Renaissance styles in Brittany.
The weather vane atop the tower features the arms of the town of Dinan.
The Tour de l'Horloge is a 15th-century granite belfry located in the heart of Dinan’s medieval old town. Standing 45 meters tall, the tower served as a symbol of the town's municipal power and wealth during the late Middle Ages. It houses a clock mechanism gifted to the town by Duchess Anne of Brittany in 1498. Visitors can climb a series of wooden staircases to reach the belfry gallery, which provides a panoramic view of the Rance Valley and the surrounding rooftops. The structure incorporates elements from both military defensive architecture and civic clock-tower design. It remains one of the most prominent landmarks in Dinan, effectively marking the historical center of the town.
The viewing gallery at the very top offers the best vantage point for sweeping shots of the medieval town architecture.
Wear comfortable, flat shoes to navigate the narrow, steep spiral wooden staircase inside the tower.
Visit the viewing gallery on a clear day to identify the layout of the medieval fortifications from above.
Space is limited inside the stairwell; wait for groups descending before starting your ascent.
Do not attempt the climb if you have mobility issues or claustrophobia, as the staircase is narrow and vertical.
Open seasonally from spring through autumn; closed during the winter months.
