The chapel of the castle, dedicated to Saint Barbara, the patron saint of artillery. Above the altar, you can see a painting of Saint Barbara, with a cannon carriage depicted behind her, honoring the artillerymen she protects.

The chapel was actively used for many years for Sunday services and other religious functions. In recent times, its use has decreased, but it was brought back into service for the baptism of Clotilde, the youngest of the three daughters. This was the last occasion it was used, making it a memorable family moment.

On either side of the chapel is a small sacristy, which contains the liturgical vestments and various accessories for religious ceremonies.
