Porta San Felice, Medieval city gate in Bologna, Italy.

Porta San Felice is the western gate of Bologna's third circle of walls, built in brick in the 13th century where Via San Felice becomes Via Aurelio Saffi at the Viali di Circonvallazione. In 1334 it received a machicolated tower and a drawbridge; a projecting forepart was added in 1509 to protect the bridge. The adjacent buildings once housed the guard corps and the toll collectors.

The gate was first built around 1250 and then substantially rebuilt in 1334 to strengthen the city's defenses. Subsequent modifications followed over the coming centuries as Bologna evolved and adjusted its fortifications.

Bolognese call the gate "pôrta ed San Flîṡ". It was the second most important gate of the third wall circuit, and the stretch of Via San Felice once included part of today's Via Ugo Bassi, from the crossing with Via Cesare Battisti and Via Nazario Sauro. The gate is also known today as Porta Saffi.

The gate sits at the intersection of Via San Felice and Via Aurelio Saffi and is easily reached on foot from the city center. It serves as a good starting point for exploring the western neighborhoods or walking along the path of the former city walls.

The gate retains its original crenellated tower, which served as a visible defensive feature. At this location, the Via Emilia changes its street name, revealing how important this spot was for ancient transportation routes.
