Sluice Štvanice

Sluice Štvanice is a navigation lock on the Vltava River in Prague that controls water levels through four successive gates. The structure connects the districts of Holešovice and Old Town and serves as a key point for river transport along the waterway.

The lock was designed by engineer Lanna and built between 1911 and 1922 to improve water management on the Vltava. The project was part of broader plans to modernize river infrastructure in Prague during the early 20th century.

The lock maintains a steady flow of tourist boats and commercial vessels through Prague, connecting various districts along the Vltava River.

The best view of the lock comes from the nearby bridges or the riverside path, where you can watch it operate. The structure is freely accessible from outside and can be visited at any time, with the most interesting periods being when boats pass through the gates.

A separate water channel runs from Children's Island to the old weir near Sova's Mills, forming an additional waterway beside the main lock. This canal was developed as part of the broader water infrastructure and helps distribute water across this section of the river.
