Saint Andrew’s Gate is one of three gates in Arcidosso’s walls giving access to the village, part of a defensive system which dates back to the 11th century. The walls originally included a bridge over Arcidosso stream, which has since fallen down and lies buried, and an anti-port, which no longer exists, from where it was possible to reach the entrance gate that leads onto Borgo Talassese. The simplicity of the original gate structure, consisting of a round arch in trachyte ashlars and moulded shelves, has been preserved. The fornix is surmounted by the black and white coat of arms of the Republic of Siena and, inside the gate on the right, the ancient guardhouse is still visible.
