The Forum of Pompeii — Heart of the Ancient City

The Heart of Roman Pompeii

The Forum (Foro) was the beating heart of ancient Pompeii — the equivalent of a modern city's main square, town hall, cathedral, and marketplace combined into a single monumental space. Located in the southwestern part of the city (Region VII), the Forum was the center of political, religious, commercial, and social life.

Layout and Dimensions

The Forum is a large rectangular open space measuring approximately 142 meters long by 38 meters wide, oriented on a north-south axis. It was paved with travertine limestone and surrounded on three sides by a two-story colonnade (portico) that provided shelter from sun and rain.

Vehicular traffic was excluded from the Forum — large stones at the entrances to the square prevented carts from entering, making it a pedestrian-only zone. Mount Vesuvius is dramatically framed at the north end of the Forum, a view that has been reproduced in countless photographs.

Key Buildings

Temple of Jupiter (Capitolium)

Dominating the north end of the Forum, the Temple of Jupiter was the most important religious building in Pompeii. Dedicated to the Capitoline Triad — Jupiter, Juno, and Minerva — it was modeled on the great Temple of Jupiter Capitolinus in Rome. After the earthquake of 62 AD, the temple was severely damaged and was still under repair at the time of the eruption.

The Basilica

The largest building in Pompeii, located on the west side of the Forum. This was the main judicial and commercial building, where legal cases were heard and business contracts were executed. Dating to the late 2nd century BC, it measures approximately 67 by 25 meters.

The Macellum

The main food market of Pompeii, located on the northeast corner of the Forum. This enclosed market hall had shops around its perimeter and a central tholos (circular pavilion) that may have been a fish market. Remains of foodstuffs including fish bones, sea urchin shells, and fruit seeds have been found here.

Temple of Apollo

Adjacent to the west side of the Forum, the Temple of Apollo is one of the oldest religious structures in Pompeii. See our dedicated page on the Temple of Apollo.

Municipal Buildings

Three large halls on the south side of the Forum served administrative functions. These included the office of the duoviri (chief magistrates), the meeting hall of the city council (ordo decurionum), and possibly an archive or treasury.

The Forum Today

The Forum is typically the first major site visitors encounter when entering from Porta Marina. Despite earthquake damage and the eruption, the layout of the Forum is clearly visible, and many of the surrounding buildings retain substantial walls and architectural features. The view of Vesuvius from the Forum is one of the most photographed perspectives at the site.
