Porta Magenta, formerly known as Porta Vercellina, was one of the city gates of Milan, Italy. The gate was established in the 9th century, with the Roman walls of the city; it was moved with the medieval and Spanish walls, and was finally demolished in the 19th century. The phrase "Porta Magenta" is now used to refer to the district ("quartiere") where the gate used to be; the district is part of the Zone 7 administrative division of Milan, west of the city centre.
