Porta Nova (Porta Volterrana)

Porta Nova, also known as Porta Volterrana, is a Medici-era gate at the entrance to Colle Alta’s Borgo di Santa Caterina. Built in 1479, it is flanked by two large circular towers and includes a short connecting wall and central arch.

Why it matters

The gate replaced Porta Selva, destroyed during the siege of Colle in 1479. Its form reflects the development of Renaissance military architecture, combining the functions of an urban entrance with features of a small fortress.

What to notice

The two round towers frame the gate and its brick wall. Defensive details include a sloping base, double cordons, machicolations, crenellations and gun ports. Recent studies also brought the moat in front of the gate back to light.

Context and history

Colle’s official tourism portal attributes the gate’s design and development to several military architects, including il Francione, Giuliano da Sangallo, Francesco d’Angelo and Paolo di Francesco. It is also traditionally called Porta Salis, a name associated with arrivals from Volterra and the salt trade.
