Pompéi, en italien, est une ancienne cité romaine préservée de Campanie, en Italie, à 23 km au sud-est de Naples, au pied sud-est du Vésuve. Elle fut construite sur un éperon formé par une coulée de lave préhistorique, au nord de l'embouchure du fleuve Sarnus (aujourd'hui Sarno).

The Basilica, with its extension of 1,500 square metres, was the most sumptuous building of the Forum, and its space was used to carry out business and for the administration of justice. It is accessed from the Forum through five entrances separated by tuff pillars; inside it is divided into three naves with two rows of brick columns with Ionic capitals. A richly decorated suggestum, where judges sat while judicial affairs were managed, is located at the centre of the short western side. The space was enhanced with an equestrian statue, whereas the walls are richly decorated with stucco like large blocks of marble. The Basilica is dated back to 130-120 BC and is one of the oldest examples of this type of building in the entire Roman world. It was excavated since the 19th century, when investigations in the Forum square area began.

This gate provides access to the west of the city and it is the most impressive among the seven gates of Pompeii. The name derives from the fact that the exit road led to the sea. The layout with a barrel vault made of concrete, that is a mixture of mortar and stones, dates back to the Silla colony (80 BC). The gate has two fornix, the main one being higher, intended for the passage of horses and pack animals; the smaller one, intended for pedestrian passage. The city wall that can be seen today, already in place in the 6th century BC, is over 3200 m long: it consists of a double wall with a walkway, protected inside by an embankment. Twelve towers, more on the north side where the flat terrain made Pompeii more vulnerable, guaranteed defense. The definitive entrance of the city within the Roman orbit decreased the importance of the walls, sometimes re-used and destroyed to make the place to homes.
