The Chiusa di Casalecchio has been in continuous operation since the 13th century, earning recognition from UNESCO as a 'Messenger of Peace' heritage site.
The dam was engineered to divert water into the Reno Canal, which once provided the hydraulic power necessary for Bologna's medieval silk industry.
The water levels in the basin are managed by the Consorzio della Chiusa di Casalecchio e del Canale di Reno to maintain the integrity of the historic canal system.
The site is part of the protected Parco Regionale dei Gessi Bolognesi e Calanchi dell'Abbadessa environmental network.
Lido di Casalecchio is a historic riverside park situated along the Reno River, anchored by the massive Chiusa di Casalecchio, the oldest functioning hydraulic work in Europe. The site features an artificial dam that creates a large, calm basin frequently used for recreational activities and cooling off during the summer months. It serves as a vital green lung for the town of Casalecchio di Reno, connecting directly to the Parco Talon. The park area offers expansive riverfront access, picnic spaces, and shaded pathways that stretch along the canal banks. Historically, the Chiusa was crucial for powering the silk mills of nearby Bologna via the Reno Canal. Visitors today utilize the gravel banks for sunbathing and relaxing by the water. The area is integrated into a broader network of cycling and walking trails that follow the Reno River valley.

Bring water shoes if you plan to walk near the riverbanks, as the terrain can be rocky and slippery.
Follow the paved paths connecting the park to the adjacent Parco Talon for a longer walking route.
Check the river flow conditions before visiting, as heavy rainfall can lead to temporary access restrictions for safety.
Do not attempt to swim in areas marked with warning signs, as strong currents near the dam can be hazardous.
Park grounds are accessible year-round, though recreational use of the riverbanks is primarily a summer activity.
Respect the river ecosystem by carrying out all trash; keep pets on a leash in designated populated areas.
