Conchetta, Navigation lock in Naviglio Pavese, Milan, Italy
Conchetta is a lock on the Naviglio Pavese featuring two parallel channels with gates that regulate water levels and allow boats to cross height differences of about 1.8 meters. The system still functions today as part of the city's network of historic waterways.
The lock was developed in 1438 by engineers Filippo degli Organi and Fioravante di Bologna as a breakthrough in water management. This early system shaped Milan's approach to canal management and water-based transport for centuries to come.
The lock system shows how Milan used its canals to move people and goods through the city. Visitors can see today how water is managed to help boats navigate different water levels.
The lock is located at Via Ascanio Sforza 61 and is visible from the adjacent pathway. Visitors should plan to visit in early morning hours or during cooler parts of the day to better appreciate the system's operation and the surroundings.
A secondary channel functions as an emergency discharge that keeps water flowing through the Naviglio Pavese even when the main lock is open for boats. This thoughtful design shows how early engineers managed multiple purposes with a single system.
