‘Santa Susanna’ Gate. It takes its name from the ancient Church of Santa Susanna, which became the Crypt of San Francesco al Prato (closed in the fourteenth century and used as a burial ground). It is also known by the name of Porta di Sant’Andrea and of the Colombata as the nearby churches of the same name. The door opens in the medieval walls, more precisely in the western boundary dating from around the thirteenth – fourteenth century, and demolished in part during the twentieth century. The remains of a small section are located in the underpass of the escalators of Viale P. Pellini. The external facade has an ogival arch, while the brick-built raising with corbels and the sculptural decoration of the pink stone griffin are later .The road that crosses it is one of the oldest roads connecting with Lake Trasimeno and Tuscany, one of the five royal roads coming from the Platea Magna. The symbols of the ward and the gate, in addition to the saint herself are: the bear, an ancient symbol, and the chain. The color is blue, probably in relation to the waters of Lake Trasimeno.
