It's located at the end of Via San Marco within the city’s Spanish walls after the “Tombun de San Marc”.
The Conca dell’Incoronata canal lock, named after the nearby 16th century church of the same name, is located at the end of Via San Marco, within the city’s Spanish walls after the “Tombun de San Marc”.
Together with the bridge behind it, it was later also known as the “Conca delle Gabelle” because at this entry point into Milan it was necessary to pay “gabelle” - indirect taxes on the trade and consumption of goods and the transport of people.
Conca dell’Incoronata was recognised as a monument with restriction no. 553 of 17 July 1967 as it is the only remains of the Naviglio Martesana in the historic centre of Milan, characterised by the last old bridge over the Naviglio, the last gate and the sentry box, remains of original navigation equipment.
Today the Conca dell’Incoronata is dry with its wooden gates decaying (even though they were restored in 1996) but identical to those designed by Leonardo da Vinci and today visible in the Codex Atlanticus (f. 240 r-c) conserved in the Biblioteca Ambrosiana of Milan, and with its bridge in “Ceppo d’Adda” stone and its brick sentry box. Restoration work overseen by Navigli Lombardi scarl and sponsored by Riva1920 is currently taking place and will involve maintenance on the Da Vinci gates of the lock and the enhancement of the Conca.
