Fort of Palaiseau

The Fort of Palaiseau is a military fortification built on a large site with a five-sided shape. Earthen ramparts and moats encircle the entire grounds to provide protection.

The fortification was built in the second half of the 19th century and formed part of a broader defensive system surrounding the capital. It served a strategic purpose in protecting the region from external threats.

The fort is named after the surrounding town and reflects the design choices of late 19th-century French military planners. Visitors can trace these intentions through the arrangement of buildings and defensive structures.

The site is only accessible with prior permission and opens mainly during special heritage events for public visits. Information about visiting should be gathered in advance.

The fort now houses a research center for aerospace technology, blending its military past with modern scientific work. This dual purpose is surprising and shows how old military sites can serve new functions.
