Citadelle de Bayonne

Citadelle de Bayonne is a French military fortress featuring four large bastions at its corners and additional defensive structures like half-moons and tenailles protecting the ditches. The entire complex follows a geometric layout with a central courtyard that currently houses an active military regiment.

The citadel was commissioned in 1680 by King Louis XIV and designed by military architect Sébastien Le Prestre de Vauban to strengthen Bayonne's defenses. The structure emerged during a period when France was modernizing its border fortifications using Vauban's influential defensive system.

The citadel displays French military design from the 17th century and became an official historical monument in 1929. Visitors can observe the characteristic architecture and defensive features of this period throughout the complex.

The citadel currently houses an active military regiment and is primarily open to visitors during special open house events throughout the year. It is wise to check ahead for scheduled opening days and wear comfortable shoes, as the grounds are extensive.

The former gunpowder storage was transformed into a ceremonial hall, while the old canteen now serves as medical facilities. These repurposing examples show how the historical structure adapted to changing military needs over time.
