Porta delle Lame, City gate in Bologna, Italy.

Porta delle Lame stands at the end of Via Lame where it becomes Via Francesco Zanardi, on Bologna's third circle of walls. The present structure is the Baroque gate rebuilt between 1674 and 1677 to Agostino Barelli's design after the medieval keep was demolished. Two bronze figures of a Partisan and a Partisan woman, made by Luciano Minguzzi in 1947, stand outside.

The original gate was built in 1334 to protect the growing city and control traffic flow. In 1677 architect Agostino Barelli completely rebuilt it, transforming it into a Baroque style structure.

The name comes from the Latin lama, meaning marsh, for the wetlands once crossed by the road leading to Trebbo di Reno and Pieve di Cento. Since 1995 the gate has housed the Luigi Fantini speleological museum of the GSB-USB group, renovated in 2018. The square is now named Piazza VII Novembre 1944.

The gate sits at the intersection of Via Lame and Via Zanardi and serves as a good landmark for pedestrians exploring the medieval walls. The location is easy to reach on foot and accessible from all sides.

The gate originally featured two separate passages, one for wagons and one for pedestrians, a design reflecting the traffic needs of the medieval city. This dual division remains visible in its structure today, even though its use has changed over the centuries.
