Porta Napoli, Baroque city gate in Lecce, Italy.

Porta Napoli is a triumphal arch gate in Lecce, built in 1548 on the site of the former Porta San Giusto. It has a single round-headed archway flanked by two Corinthian columns on each side, resting on square bases and supporting a triangular pediment. The pediment holds the Habsburg imperial coat of arms of Charles V, with cannons and armour carved around it, and a Latin inscription runs below.

The gateway was built in 1548 during the reign of Charles V and replaced an earlier passage known as Porta San Giusto. It was constructed as part of the city's defense system to control access to the urban area during that period.

The gate's name comes from the consular road to Naples that began here. Its Latin inscription praises Charles V as conqueror of the Turks, and the pediment shows cannons and armour in the manner of Roman triumphal arches. Excavations by the University of Salento nearby uncovered Messapian burials with grave goods.

Porta Napoli stands beside the small Piazzetta Arco di Trionfo, facing the Obelisk of Terra d'Otranto, at the edge of Lecce's historic centre. The gate is reached on foot through the surrounding streets; the 19th-century rebuilding of the city walls left it free-standing, so it can be viewed from both sides. The area around it has been excavated by the University of Salento.

The structure gets its name from the ancient road that connected Lecce directly to Naples, making it a major passage for trade and travel. Archaeological discoveries near the site reveal that Messapian people inhabited this region in ancient times.
