Chiusa di Casalecchio di Reno, Medieval water lock in Casalecchio di Reno, Italy
The Chiusa di Casalecchio di Reno stands on the Reno River, controlling water flow through a complex system of gates and channels at the transition from mountains to plains.
Built in 1183 and relocated in 1360 under Cardinal Egidio Albornoz's direction, the lock became instrumental for Bologna's water management and industrial development through centuries.
The lock sustained Bologna's silk industry from the 13th to 18th centuries by providing water power to silk-throwing mills across the canal network.
Modern visitors can explore the lock structure and surrounding paths along the Reno River, with guided tours available through local heritage organizations.
The UNESCO recognized this hydraulic engineering structure in 2010 as a Peace Messenger Heritage site for its contribution to local development.
