Tour du Connétable de Vannes

The Constable Tower is a five-story defensive structure in Vannes with polygonal rooms and a spiral staircase contained in a turret. Its lower sections feature openings designed for cannon placement, while the upper levels have larger windows that provided both light and views across the land.

Construction took place between 1399 and 1442 under Duke Jean V of Brittany as part of the fortifications surrounding the lower courtyard of Hermine Castle. The structure later served as a prison during the French Revolution in 1795, holding captured émigrés involved in events at Quiberon.

The openings and interior details show the craftsmanship of skilled builders who created spaces for the ducal court, where important people once gathered. Visitors can observe how the design reflected the power and status of those who lived here.

The site functions as an exhibition space, accessible to visitors through organized tours arranged by Vannes. Access is typically scheduled, so planning a visit in advance is helpful to ensure entry.

The spiral staircase within the tower represents a clever building solution that connected the floors efficiently without taking up much floor space. This design approach was common in medieval towers and demonstrates the practical engineering skill of that era.
