Chatou lock

Chatou lock is a navigation and water control facility on the Seine River that regulates water levels for boat passage and manages river flow. The structure combines lock gates and dam components that work together to balance different water levels for vessels to pass through safely.

The lock was built as part of modernizing navigation routes on the Seine and enabled the transport of goods along the river. The structure contributed to a network of water control facilities that supported commercial use of the river over centuries.

The structure earned recognition in the general inventory of cultural heritage, marking its importance in French engineering and architectural achievements.

The structure sits directly on the Seine and can be observed from the surrounding riverbank areas when boats pass through the lock. The best view of its operation comes from the banks or walkways near the facility.

The dual-purpose infrastructure functions both as a lock for navigation and a dam for water management, demonstrating advanced engineering integration.
