شلايز هو هويس في بيچي يربط waterways at different levels, allowing vessels to travel through the canal system in northern Serbia. The structure features chambers and gates that regulate water flow and enable boats to move between elevated sections.

The lock was built in 1900 as a collaboration between engineer Albert Eiffel's workshop and technical director Albert Hjanc. The project brought major improvements to water transport systems in the region.

The lock structure represents an important engineering landmark in the region, showcasing technical innovation from the early 1900s. Its recognition as a Cultural Monument reflects how locals view it as a symbol of industrial progress and regional identity.

The structure sits along the Tisza River as part of the Danube-Tisa-Danube canal system, which attracts boats regularly. Visitors can walk around the area and watch the lock in operation when boats pass through.

The lock served as the birthplace of water polo competitions in the region, with organized sporting events starting here before spreading to other areas. This early sports activity made the location a hub for regional athletics.
