The door of Marina Grande is the oldest of the city’s gates with characteristics of the ancient Greek doors. Its existence was documented by the abbot Giovan Battista Pacichelli in map of the city which dates back to the 18th Century. The door was originally located under a tower but little of this remains today. It is thought to have been the sole entrance into the town in the 15th Century from the seaward side and along with the other gate in Marina Piccola was the town’s trade route.
