The Medieval Porta Ticinese (Porta Ticinese Medievale) is a gate of the former 12th-century Walls of Milan; it is located at the intersection of the Corso di Porta Ticinese and Via Edmondo de Amicis (running to west) and Via Molino di Armi (running to east) in the city center of Milan, region of Lombardy, Italy.

The structures we see today were stripped of accumulating houses and refurbished as see them now in 1861 by Camillo Boito.

The canal was filled in over the last century creating the intersecting avenues of Amicis and Molion di Armi.

As the city grew, by the 16th-century, a second moated set of walls with a second distinct Porta Ticinese developed some 500 meters to the South at the site known as the Darsena del Naviglio, or Port of the Canal, and then replaced over in the 19th century with a neoclassical structure by Luigi Cagnola.

The first is the adaptation of the Spanish word "chica", meaning little girl, since the gate was the only one having just one access, whereas the latter is a dialectical form of its name.
