Katedralna Lock in Poznań, Hydraulic fortification in Ostrów Tumski, Poland.
The Katedralna Lock combines a weir system with defensive elements, featuring stone walls and water control mechanisms along the Cybina River in Poznań.
Karl von Grolman designed this engineering structure in 1839 as part of the expanding Poznań Fortress, integrating water management with military defense capabilities.
The lock stands as a registered Polish cultural heritage site, demonstrating the technological advancement of 19th-century hydraulic engineering in urban development.
Visitors can observe the lock's mechanisms while exploring the surrounding Ostrów Tumski area, with information panels explaining its technical functions.
The structure maintains its original dual purpose of water level control and fortification, representing a combination of civil and military engineering.
