Wielka Śluza, Hydraulic engineering structure in Poznań, Poland
The Wielka Śluza spans 82 meters with a width of 19 meters, featuring 12 spans and two central openings for vessel navigation on the Warta River.
Built around 1832 under engineer Karl von Grolman's supervision, this structure formed part of the initial defensive components of Poznań's polygonal fortress system.
The lock represents a testament to 19th-century military architecture and engineering, demonstrating the technical capabilities of Prussian fortress construction methods.
The remaining eastern and western abutments of the lock provide visitors with insights into historical water management systems and fortification techniques.
The structure used bricks transported from Gorzów Wielkopolski and Murzynów, incorporating vertical gates within pillars to control water levels for defensive flooding.
