Porta a Lucca, Medieval city gate in Pisa, Italy.

Porta a Lucca is a stone gateway standing along the northern defensive walls of Pisa and features solid medieval construction with sturdy archways and thick stonework. It marks a distinct section of the city's historical fortification system that once protected the urban area.

The gate was opened by the Florentines during their rule of Pisa in the second half of the 16th century, replacing the nearby Porta del Parlascio, which was closed by the bastion of the same name. Between 1928 and 1952 the tracks of Pisa's tram network ran through it.

The gate gives its name to the surrounding residential district, home to about 20,000 people. Beyond it lies Largo del Parlascio, where the Bagni di Nerone, an ancient Roman ruin, stands. In the same district are the Arena Garibaldi - Romeo Anconetani stadium of A.C. Pisa 1909, the CAPAR paratrooper training centre of the Folgore Brigade and the CUS Pisa university sports centre.

The gate is best reached on foot by walking northward from the Field of Miracles and following the line of the ancient walls through the city. The area is clearly marked and several public transportation stops are nearby if you need additional travel options.

Near the gate are remnants of the Terme di Nerone, ancient Roman thermal baths, which create a rare overlap of two different historical periods in one location. Visitors can see both Roman and medieval layers of the city's past at this spot.
