Citadelle de Calais

Citadelle de Calais is a 17th-century military fortress featuring massive stone walls, deep moats, and angular bastions designed using advanced military engineering principles of its era. The structure displays the defensive architecture typical of fortifications built during this period.

Built between 1667 and 1707 on orders from Louis XIV, the fortress was constructed to protect the strategic harbor from invasion threats. Its construction reflected France's efforts to strengthen its northern defenses during that era.

The fortress hosts exhibitions that explore the complicated shared history between France and England through artifacts and documents on display. These spaces help visitors understand how this location shaped relationships between the two nations.

Guided tours are available daily from April through October, providing access to the ramparts where visitors can view the city below. Walking the walls helps you understand the full layout and design of the fortification.

The fortress contains underground passages and chambers that once allowed communication between different sections during times of siege. Walking through these hidden tunnels today reveals how carefully the defensive system was planned.
