Conca dell'Incoronata, Navigation lock in Via San Marco, Milan, Italy.
Conca dell'Incoronata is a navigation lock at the terminus of the Naviglio Martesana canal in Milan, featuring stone construction and original gates. The structure allowed boats to move between different water levels as they entered the city.
The lock was built in the 15th century and later improved by engineers including Leonardo da Vinci during the 16th century. These modifications created a reliable water management system for boat traffic entering Milan.
The lock takes its name from a neighboring 16th-century church and served as a checkpoint where merchants conducted official business. Visitors can still observe details that reflect this role in the city's trading history.
The site is located on Via San Marco in the city center and remains open throughout the day without entrance fees. It connects easily to nearby neighborhoods and is accessible on foot from major transit points.
The lock retains the final remaining bridge spanning the Naviglio Martesana within central Milan. Original navigation equipment from past centuries remains visible at the site.
