Sluice Modřany

Sluice Modřany is a navigation lock on the Vltava River in Prague that allows boats to pass through the waterway. The facility contains three chambers separated by tall concrete barriers and extends approximately 87 meters along the river.

The lock was built between 1979 and 1987 as part of efforts to improve river navigation on the Vltava. This project was a major undertaking that expanded water transport capabilities throughout the waterway system.

The lock is part of a long chain of waterworks built to manage the Vltava and enable boat traffic through the river. You can observe how this structure fits into a larger system that shaped local life and transportation for generations.

The lock is accessible during regular daytime hours, with passage available by request outside standard times. Be prepared for wait times when multiple boats need to pass through simultaneously.

A service tunnel runs beneath the lock chamber below the river, built with reinforced protection. This hidden element reveals how engineering challenges are solved under the water's surface to keep everything functioning.
