Porta dei Pispini, Medieval gate in Siena, Italy

Porta dei Pispini is a gate in Siena's eastern medieval wall, built in 1326 to a design attributed to Minuccio di Rinaldo. It has an outer defensive wall with a single archway, topped by a crenellated parapet supported on small corbel arches. A brick bastion with a cross-shaped plan and three overlapping semicircular rooms stands to its left.

The gate was built in 1326 by architect Minuccio di Rinaldo and originally displayed a fresco by artist Sodoma. That fresco was later moved to the Basilica of San Francesco.

The gate marks the historical point where the relics of Sant'Ansano entered the city, leading to its initial name Porta San Viene.

The gate sits at the corner of Via Pispini and Via Aretina and is straightforward to reach when exploring the eastern side of the old city. The location makes it easy to walk around the nearby walls and view other medieval structures on foot.

The small brick fortino beside the gate, built by Baldassarre Peruzzi between 1527 and 1532, has a cross-shaped plan of three overlapping semicircular rooms, not stacked floors. It follows the model of Francesco di Giorgio Martini's bastions at Urbino, where small forts were first designed to sit inside an existing wall circuit.
