Google MapsHistory of the Forum Basilica of Pompeii

The Forum Basilica was built in the 2nd century BC as part of the project to monumentalize the city’s forum. Its construction occurred between 130 and 120 BC, a period marked by intense building activity aimed at making Pompeii’s political and commercial centre an example of Roman grandeur.
The Forum Basilica was already in use in the first century B.C., as evidenced by a graffito found during excavations, which reads:
“Caius Pumidius Dipilus was here on October 3, in the year of the consulship of Marcus Lepidus and Quintus Catulus.”
This clue confirms the Forum Basilica’s importance as a public and legal activity centre in Pompeii’s daily life.
Architecture and Plan of the Forum Basilica of Pompeii

The Forum Basilica is located in the southwestern corner of the forum and is one of the city’s largest and most monumental structures. Its rectangular plan measures about 55 meters long by 24 meters wide, making it one of the most impressive basilicas in the Archaeological Excavations of Pompeii.
The construction of the Forum Basilica required the demolition of numerous houses and stores and the filling of a hillside to obtain a regular surface.
Main Architectural Elements

- Portico of Popidius: Located near the main entrance, this portico concealed some irregular buildings on the southern side of the forum.
- Main entrance: Located along the east side, characterised by five doors divided by tufa pillars. Two secondary entrances are located along the north side, directly on Via Marina, and on the south, built in the Augustan age.
- Central nave and columns: Inside the Forum Basilica, the central nave is surrounded by 28 columns of the Ionic order, about 11 meters high. The side columns are semicircular and positioned along the perimeter walls with Ionic capitals.
- Tribunal: Located along the western side, the tribunal was accessible by a wooden staircase bordered by six columns of Corinthian order. Justice was administered here, divided into two large rooms separated by pilasters.
Functions of the Forum Basilica of Pompeii
The Forum Basilica served two main functions in ancient Pompeian society:
- Tribunal: It was the place where the tasks of justice were administered. Hearings, trials and judicial decisions were held in this monumental space.
- Commercial exchange venue: The Forum Basilica also housed covered commercial activities, providing a safe and sheltered space where citizens could conduct business without fear of the weather.
This dual function made the Forum Basilica an essential hub of Pompeii’s public life, combining civic and commercial aspects into one grandiose structure.
The Decoration and Illumination of the Forum Basilica of Pompeii

The lighting inside the Forum Basilica remains uncertain, as does its original roof, which presumably must have been double-sloped. Inside, numerous columns and capitals remain, which probably did not belong to the original structure and were inserted later.
The interior walls show few traces of decoration, all done in the early style with stucco in imitation of marble blocks, evoking a restrained and functional elegance.
The Discovery and Research of the Forum Basilica of Pompeii
Buried under a blanket of ash and lapilli during the eruption of Vesuvius in 79 AD, the Forum Basilica was rediscovered in the early 19th century, thanks to excavations promoted by the Bourbon dynasty. Investigations continued at various times until 1950, progressively revealing the function and importance of the Forum Basilica through the discovery of graffiti and internal structures.
The discovery of the Forum Basilica represents one of the highlights of the Archaeological Excavations of Pompeii, as it provided a better understanding of the social and political organisation of the city, as well as valuable information on the legal and commercial practices of the time.
