The urban settlement, in its oldest nucleus, is tipically characterized by a Greek-Roman lay-out, where the road system is composed by parallel streets forming rectangural insulae (blocks) measuring about 80 meters by 50.The decumanus Maximum is in fact still recognizable in the today Via San Cesareo and Via Fuoro, while the cardo Maximum corresponds to Via Tasso.
In the corner which Via S.Cesareo forms with the Tasso square once stood a second Seat called Porta because it was originally built near the city's main gate in the area then called largo del Castello.
After the abolition of the seats it was first turned into a prison and then a guard-house for the urban militia and finally a meeting place for the Sorrentine club.
