The "Casa 770" in Milan is the only replica in Europe of the original building in Brooklyn, home to the Chabad-Lubavitch Orthodox Jewish movement. Built in the 1960s, it replaced a dilapidated building once owned by a Jewish family. Rabbi Gershon Mendel Garelik envisioned recreating the original 770 design to house a library, offices, and a study centre. The Milan location serves as a centre for the Chabad-Lubavitch movement in the city.
There are 12 houses like this in the world, and it's a nice, and weird for Milan, building to see if you are in the Porta Venezia neighbourhood.
