The last surviving lock of the Naviglio della Martesana inside the Spanish walls, built from 1496, with wooden gates identical to the ones Leonardo drew in the Codex Atlanticus. The stone bridge and the toll-keeper's brick hut are why the Milanese also called it the Conca delle Gabelle: boats paid duty here to enter the city.

Good to know
- The canal was filled in in 1929-1930, so the lock is dry.
- Two minutes from Santa Maria Incoronata, whose name it takes; pair with a Brera walk.
- in-Lombardia reports maintenance of the Leonardo-type gates by Navigli Lombardi.
