Poznan Fortress Days - Cathedral Sluice
The Cathedral Sluice as one of the fortress’s first hydraulic structures was a part of Ostrów Tumski’s (eng. Cathedral Island) reinforcements. Completed largely in 1834-1838, it mostly had the function of a weir in the case of flooding danger from the waters of Cybina river. It also enabled communication between Cathedral Island and Śródka.
