TIL that the canals in Navigli werent just for transport, Leonardo da Vinci actually redesigned the
been living here 4 years and somehow never really thought about why the neighborhood is called Navigli in the first place. the canals were originally built way back starting in the 1100s to connect Milan to the surrounding rivers and lakes for trade. but heres the part that got me - in the late 1400s Ludovico Sforza hired Leonardo da Vinci to improve the lock system on the Martesana canal so boats could handle the elevation changes better.
he designed a system of consecutive locks that let boats move between different water levels without basically draining the whole canal each time. the dude was doing hydraulic engineering while also painting the Last Supper across town, kinda wild to think about.
you can still walk along the Naviglio Pavese and see remnants of that infrastructure, tho alot of it has been modified over the centuries. theres actually a dedicated path along the Martesana canal that goes all the way out towards Adda, been meaning to bike it one of these weekends. the lock at Conchetta is apparently one of the best preserved examples of the original design.
crazy that my aperitivo spot is sitting on top of 500 year old engineering thats still functional lol
