Citadelle de Laon, Military stronghold and city gate in Laon, France
The Citadelle de Laon features a fortified entrance gate connected to extensive ramparts, with deep moats and a drawbridge controlling access to the city.
Henri IV ordered the construction of this citadel in 1594 after a three-month siege, requiring the demolition of the Saint-Georges district and two churches.
The citadel's underground passages reveal the engineering methods of 16th-century military architecture through guided tours called 'Secrets under the City'.
The administrative complex includes free parking facilities and picnic areas, while the former powder magazine and underground tunnels welcome visitors daily.
In 1870, the warehouse keeper ignited the powder magazine, causing significant casualties and structural damage throughout the surrounding area.
