Hagestein weir-lock complex

The Hagestein weir-lock complex in Vianen sits on the Lek River and combines two separate structures for water control and vessel passage. The weir and lock system work together to regulate water levels and provide boats with different routes depending on water conditions.

Built in 1960, the complex was part of a post-war program to modernize river control systems on the Nederrijn and Lek. It represents how the country rebuilt its water management infrastructure during that reconstruction period.

The complex showcases Dutch functionalist design by architect Wouter Hamdorff and carries national monument status. Its straightforward, practical form reflects how the country has always approached engineering as visible public art.

When water levels rise, vessels can pass directly under the open weir, but during low water conditions they must use the lock instead. Watching these different operating phases from the riverbank shows how water management changes with the seasons.

A hydroelectric power station sits inside the weir's central pillar, generating electricity while regulating water levels. This dual function shows how Dutch engineers combined multiple purposes into a single structure.
