The lock was constructed between 1902 and 1905 as part of a major project to modernize navigation on the Vltava River.
The lock is notable for its 'hoisting' mechanism where the gates are raised vertically into a steel superstructure.
It is classified as a protected Cultural Monument of the Czech Republic.
The lock complex includes a small hydro-electric power plant that has been in operation since the early 20th century.
The architectural design of the lock-keeper's house and control towers was influenced by the castle architecture of nearby Mělník.
The Hořín lock is a significant 1905 technical monument situated on the Vraňany–Hořín canal near the confluence of the Vltava and Elbe rivers. It features two chambers designed to overcome a height difference of approximately 8.5 meters. The site is noted for its Neo-Renaissance administrative buildings and stone-clad gate structures that retain their original early 20th-century aesthetic. These locks serve as the final stage of the Vltava Waterway, connecting it to the Elbe. The machinery still utilizes original electrical drive systems integrated into the historic architecture. The site serves as a vital junction for both commercial river transport and recreational boating in Central Bohemia.

Observe the lock operation from the elevated pedestrian walkway for the best perspective of the water level changes.
Combine your visit with a walk along the adjacent cycle paths that follow the canal toward the Mělník confluence.
Check the Vltava Waterway navigation schedule online if you hope to see a vessel transiting the lock.
Do not attempt to cross the lock gates when they are in motion or restricted by safety barriers.
Operating hours depend on the river navigation season and current water levels; limited usage during winter months or flood conditions.
