Also known as Porta della Colombata or di Sant’Andrea, from the names of the nearby homonymous churches, it is part of the medieval walls (13th-14th cent.). Demolished in the 1900s, all that remains is the ogival arch and the more recent brick storey above it, decorated with a nice griffin of pink stone. Attached to the gate is the ancient church of Sant’Andrea Apostolo, formerly a chapel in 1168, reconstructed in the 19th century, with interesting terracotta elements on the façade (portal and rose-shaped window).
