This is an old city gate built in Renaissance style. Once it had been joined to the city walls, but when those were expanded in the 15th century, the gate was left free-standing. Now it just looks like some kind of Arc du Triomphe. The two towers symbolise honor and virtue; on the door you’ll find the 16th century coat of arms of Charles V, and just close to the gate is the church of Santa Caterina a Formiello. There’s not much else to see though.
