Religion was deeply integrated into the public and private life of ancient Pompeii. Temples and sanctuaries occupied some of the most prominent locations in the city, particularly around the Forum and the theatre district, while smaller shrines and domestic lararia brought religious practice into houses, shops and workplaces.
The sacred landscape of Pompeii developed over many centuries. Some sanctuaries originated during the earliest phases of the settlement, long before Pompeii became a Roman colony, while others were built or transformed during the Roman period. The result was a religious environment in which Italic, Greek, Roman and Egyptian traditions existed side by side.
The temples preserved today therefore tell much more than the history of individual gods. They reveal Pompeii's changing political relationships, its connections with the wider Mediterranean world and the way religion became intertwined with civic identity and imperial power.
Sanctuary of Apollo
The Sanctuary of Apollo is one of the oldest places of worship in Pompeii and occupies a prominent position beside the Forum, along the ancient route leading from Porta Marina towards the centre of the city.
Archaeological investigations have revealed evidence of a sanctuary in this area as early as the 6th century BC. These early phases belong to the Archaic history of Pompeii, when the settlement was strongly influenced by the Greek and Etruscan cultures present in Campania.
The sanctuary underwent major transformations over the centuries. Between the 3rd and 2nd centuries BC, the earlier sacred area was extensively rebuilt, creating the general arrangement that survived, with later alterations, until AD 79.
The temple stood on a raised podium within a large courtyard surrounded by a portico. In front of it was the altar used for sacrifices.
Bronze statues of Apollo and his twin sister Diana were found in the sanctuary. The originals are now preserved in the National Archaeological Museum of Naples, while copies are displayed at Pompeii.
A sundial was also located within the sanctuary, illustrating the combination of religious, civic and ceremonial functions that characterised this important area.
The Sanctuary of Apollo remained closely connected with the Forum and therefore occupied a central position in Pompeii's public life throughout much of the city's history.
Temple of Jupiter – the Capitolium
Dominating the northern end of the Forum is the Temple of Jupiter, one of the most recognisable monuments of Pompeii.
The temple was constructed during the 2nd century BC, when Pompeii was undergoing a major programme of monumental development.
After the foundation of the Roman colony in 80 BC, the sanctuary was transformed into a Capitolium, dedicated to the Capitoline Triad of Jupiter, Juno and Minerva, reflecting the political and religious institutions of Rome.
The temple stood on a high podium approached by a broad staircase. Its position was carefully chosen so that the building dominated the Forum, with Mount Vesuvius rising dramatically behind it when viewed from the square.
The cella housed the cult statues of the three deities. Beneath the podium were underground chambers known as favissae, originally associated with the storage of sacred offerings and possibly used at a later stage for other purposes.
The temple was severely damaged by the earthquakes that affected Pompeii during the final decades of its existence.
When Vesuvius erupted in AD 79, restoration work had not yet returned the Capitolium to its former appearance. Its incomplete condition is therefore another reminder that Pompeii was still undergoing extensive reconstruction at the time of the disaster.
Sanctuary of Venus
The Sanctuary of Venus occupies a large terrace on the western edge of the city, overlooking the area where the ancient coastline and harbour were located.
Venus was of particular importance to Roman Pompeii. Following the establishment of the colony in 80 BC, the city officially bore the name Colonia Cornelia Veneria Pompeianorum, and Venus became closely associated with its civic identity.
The sanctuary itself had earlier origins. The first monumental complex in this location dates to the 2nd century BC, although the remains visible today largely reflect later rebuilding during the Roman Imperial period.
Its position above the coast was particularly impressive and may also have reinforced the association between Venus and navigation.
The sanctuary suffered extensive damage during the earthquake of AD 62 and subsequent seismic activity. Reconstruction had not been completed when Pompeii was destroyed seventeen years later.
During the excavations, archaeologists discovered a large gold lamp weighing almost 900 grams, preserved today in the National Archaeological Museum of Naples.
The unfinished condition of the Sanctuary of Venus provides important evidence for the scale of the reconstruction taking place throughout Pompeii during its final years.
Temple of Isis
The Temple of Isis, located in the theatre district, is one of the most fascinating religious buildings in Pompeii and one of the clearest examples of the city's connections with the wider Mediterranean world.
The cult of the Egyptian goddess Isis spread widely across the Mediterranean during the Hellenistic and Roman periods. At Pompeii, a sanctuary dedicated to her existed before the establishment of the Roman colony.
The temple was badly damaged by the earthquake of AD 62 but was completely rebuilt before the eruption.
An inscription records that the reconstruction was carried out in the name of Numerius Popidius Celsinus, who was only six years old. His father, a wealthy freedman, almost certainly financed the work in his son's name. In return, the young Celsinus was admitted to the local council.
The temple stood on a high podium in the centre of a porticoed courtyard.
In front of the temple were the altar and a small building known as the purgatorium, connected with the ritual use of sacred water. Behind the temple were rooms used by members of the cult, including an ekklesiasterion for meetings and a sacrarium decorated with scenes connected with the mythology of Isis.
When the sanctuary was excavated in the 18th century, much of its decoration and furnishings survived. Many of these objects and paintings were subsequently transferred to the National Archaeological Museum of Naples.
The Temple of Isis became one of the buildings that helped make Pompeii famous throughout Europe during the early history of the excavations. Wolfgang Amadeus Mozart visited Pompeii with his father Leopold in 1770, and the sanctuary has often been associated with the Egyptian atmosphere later found in The Magic Flute.
Temple of Fortuna Augusta
The Temple of Fortuna Augusta stood at an important intersection north of the Forum.
It was constructed during the reign of Augustus by Marcus Tullius, a prominent Pompeian magistrate, who financed the building himself and erected it on land belonging to him.
The relatively small temple stood on a podium and was approached by a staircase. Marble columns and capitals gave the façade a prestigious appearance, while an altar stood in front of the building.
The principal cult statue represented Fortuna Augusta, while statues connected with members of the imperial family occupied niches within the cella.
The temple illustrates an important transformation in the religious life of Pompeii during the early Roman Empire. Worship was increasingly associated not only with traditional gods but also with the emperor and the imperial household.
For ambitious members of the local elite, financing monuments connected with the imperial cult could also demonstrate loyalty to Augustus and reinforce their own political status within the city.
Sanctuary of the Public Lares
On the eastern side of the Forum stood the large building generally identified as the Sanctuary of the Public Lares.
The Lares were protective deities deeply rooted in Roman religious life. Within houses, domestic Lares were worshipped at small shrines known as lararia, while the public cult concerned the protection and collective identity of the community.
The Pompeian sanctuary has an unusual and elaborate plan, with a large central space surrounded by niches and architectural elements.
Its precise history and interpretation have been much debated, and it is therefore preferable not to connect its construction too confidently with a single historical event.
What is clear is that the building formed part of the monumental religious and political landscape developed around the Forum during the Roman period.
Its location beside buildings associated with the imperial cult also illustrates how traditional religious practices and the new political language of imperial Rome could coexist within the civic centre.
Temple of the Genius Augusti
Beside the Sanctuary of the Public Lares is the building traditionally known as the Temple of Vespasian.
Modern interpretation generally identifies it more cautiously as the Temple of the Genius Augusti, linking it with the imperial cult rather than exclusively with Emperor Vespasian.
The sanctuary consisted of a courtyard with a small temple or shrine at the rear and an altar placed prominently in front.
The marble altar is one of the most interesting surviving elements and is decorated with a scene of animal sacrifice, providing valuable evidence of the ceremonies associated with Roman public religion.
The sanctuary belonged to the group of monuments on the eastern side of the Forum that expressed Pompeii's relationship with the emperor and the Roman state.
Its traditional name is still encountered in older guidebooks and publications, so visitors may find both Temple of Vespasian and Temple of the Genius Augusti used for the same building.
The Doric Temple and the Triangular Forum
One of the oldest sacred areas of Pompeii occupied the Triangular Forum, on the southern edge of the ancient city.
At its highest point stand the remains of the so-called Doric Temple, whose earliest monumental phase belongs to the Archaic period.
The sanctuary was associated with Athena, while archaeological and epigraphic evidence also connects Hercules with the sacred area.
Its spectacular position overlooking the Sarno plain and the ancient coastline demonstrates the importance of the sanctuary during the earliest development of Pompeii.
The temple underwent modifications over time, while the surrounding area was later reorganised as the Triangular Forum, with a long portico framing the sacred space.
The survival of this sanctuary alongside later Roman temples shows how ancient places of worship could remain important even as the city's political and religious landscape changed.
Other cults and sacred spaces
The major temples represent only part of Pompeii's religious life.
Other sanctuaries and places of worship existed within and outside the city, while evidence from inscriptions, statues, paintings and votive offerings documents devotion to numerous gods.
The cults of Hercules, Dionysus or Bacchus, Ceres, Mercury and other deities are well represented.
Recent archaeological research has also transformed our understanding of Pompeii's earliest religious history. Excavations in sacred areas such as the Fondo Iozzino sanctuary, outside the ancient walls, have produced votive offerings and inscriptions dating back to the Archaic period.
The finds include weapons, jewellery, pottery and Etruscan inscriptions, demonstrating the extraordinary cultural diversity of Pompeii centuries before the Roman conquest.
Religion was therefore continually changing as the city developed contacts with neighbouring Italic communities, Greeks, Etruscans and, later, the wider Roman and Mediterranean worlds.

Religion inside the home
Religious practice did not take place only in monumental temples.
Many Pompeian houses contained a lararium, a domestic shrine dedicated to protective deities. These could range from simple painted niches to elaborate architectural structures decorated with paintings and sculpture.
The Lares, the Genius of the head of the household and other divine figures could be represented together. Snakes frequently appear beneath domestic shrines and were associated with prosperity, fertility and the protection of the household.
Shops, workshops and commercial establishments also contained religious images.
At the Thermopolium of Vetutius Placidus, for example, the shrine painted on the counter includes deities connected with commerce, wine and protection.
The religious life of Pompeii therefore extended from monumental civic temples to the most ordinary spaces of everyday life.
Religion and imperial power
The transformation of Pompeii into a Roman colony in 80 BC gradually changed the city's religious landscape.
The Temple of Jupiter became a Capitolium dedicated to Jupiter, Juno and Minerva, while Venus acquired an even stronger role as patron goddess of the colony.
Under Augustus and his successors, new monuments celebrated the imperial household and the political order of Rome. The Temple of Fortuna Augusta, the Temple of the Genius Augusti and other buildings around the Forum demonstrate how religion, political loyalty and civic ambition became closely connected.
Local magistrates and wealthy citizens could finance religious buildings as a way of displaying generosity towards the community and loyalty towards Rome.
At the same time, older cults continued to flourish. The Sanctuary of Apollo remained important, while the reconstruction of the Temple of Isis after the earthquake demonstrates the continued vitality of a cult whose origins lay far beyond Italy.
Pompeii therefore preserved a remarkable combination of ancient local traditions and new forms of Roman religious identity.
The earthquake and the temples of Pompeii
The earthquake of AD 62, followed by further seismic activity, caused serious damage to many of Pompeii's sacred buildings.
The consequences differed from one sanctuary to another.
The Temple of Isis was rebuilt rapidly and was once again richly decorated before AD 79. By contrast, the great Sanctuary of Venus was still undergoing reconstruction when the eruption occurred, and the Temple of Jupiter had not completely recovered from the damage.
These differences provide valuable evidence about the priorities, resources and communities associated with individual cults.
They also reinforce one of the most important facts about the Pompeii visible today: the city was not a perfectly completed Roman town frozen at a single moment, but a place undergoing continuous repair, redevelopment and change when Vesuvius erupted.
Visiting the temples of Pompeii
Several of Pompeii's most important sacred buildings can still be seen along the principal visitor routes.
The Sanctuary of Apollo, Temple of Jupiter, Sanctuary of Venus, Temple of Fortuna Augusta, Sanctuary of the Public Lares and Temple of the Genius Augusti are concentrated in or close to the Forum, making it possible to understand the relationship between religion and the civic centre.
The Temple of Isis and Doric Temple lie farther south in the theatre and Triangular Forum area.
Opening conditions can change because of conservation work or visitor management. Before visiting, check the official list of buildings currently accessible in Pompeii.
Together, the temples of Pompeii provide an exceptional record of more than six centuries of religious history, from the Archaic sanctuaries of Apollo and Athena to the imperial cult monuments of the Roman colony.
They reveal a city whose religion was never static but continually absorbed new gods, political ideas and cultural influences while preserving traditions inherited from its distant past.
