# Olympia
**Olympia** is an ancient sanctuary site in the western [Peloponnese](https://www.edgepedia.org/peloponnese), Greece, dedicated to Zeus and the birthplace of the Olympic Games, which were celebrated there every four years from 776 BC to 393 AD. The site lies in a valley formed by the confluence of the Alpheios and Kladeos rivers, in the Regional Unit of Eleia (Elis), and its sacred grove, the Altis, held one of the highest concentrations of masterpieces of the ancient Greek world[1](https://whc.unesco.org/en/list/517/). Inhabited since prehistoric times, Olympia became a center for the worship of [Zeus](https://www.edgepedia.org/zeus) in the 10th century BC and developed, from the 8th century BC until late Roman times, the most characteristic ensemble of athletic facilities and religious buildings of the ancient world[1](https://whc.unesco.org/en/list/517/) • [2](https://arxaiaolympia.gov.gr/the-archaeological-site-of-olympia/?lang=en). It has been inscribed on the UNESCO World Heritage List since 1989[1](https://whc.unesco.org/en/list/517/) • [3](https://www.dainst.org/en/dai-standorte/athens/research/150-years-of-german-excavations-at-olympia).

## The sanctuary and its monuments
The heart of the site was the Altis, the sacred grove consecrated to the gods, enclosed by a wall that separated the temples and religious edifices from the secular buildings[1](https://whc.unesco.org/en/list/517/) • [2](https://arxaiaolympia.gov.gr/the-archaeological-site-of-olympia/?lang=en). Within the precinct stood the principal temples of Zeus and Hera, the ancient Pelopion sanctuary, and a row of treasuries, small edifices dedicated by the various city-states, at the foot of Kronion Hill[1](https://whc.unesco.org/en/list/517/) • [2](https://arxaiaolympia.gov.gr/the-archaeological-site-of-olympia/?lang=en). Around the divine precinct were the Theokoleon, residence of the priests; the Bouleuterion, the administrative building; the Prytaneion of the Eleans; the Leonidaion, the largest building at Olympia, erected in the fourth century BC as a guest house; and accommodations for distinguished guests such as Nero's House[1](https://whc.unesco.org/en/list/517/) • [2](https://arxaiaolympia.gov.gr/the-archaeological-site-of-olympia/?lang=en).
**The Temple of Zeus** was the outstanding monument. Designed by the architect Livonas, it was a peripteral Doric temple built of local shelly limestone coated with stucco, with metopes, pediments, and sculptures of marble; at the far end of the central aisle of the cella sat the chryselephantine (ivory and gold) statue of Zeus by the sculptor Pheidias[2](https://arxaiaolympia.gov.gr/the-archaeological-site-of-olympia/?lang=en). UNESCO describes this cult statue as one of the seven wonders of the ancient world, now lost[1](https://whc.unesco.org/en/list/517/). The temple of Zeus, built in 470–457 BC, served as a model for the great Doric temples constructed in the Peloponnese, southern Italy, and Sicily during the 5th century BC[1](https://whc.unesco.org/en/list/517/).
**The Temple of Hera** is earlier, dated to 600 BC, and is also peripteral in the [Doric order](https://www.edgepedia.org/doric-order). The Princeton Encyclopedia of Classical Sites calls the Heraion, narrow and of heavy proportions, the oldest example of a monumental temple in Greece[5](https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0006%3Aentry%3Dolympia). In 1877 the statue of Hermes, a work of Praxiteles, was discovered in its cella[2](https://arxaiaolympia.gov.gr/the-archaeological-site-of-olympia/?lang=en). Other surviving monuments include the Metroon, a Doric peripteral temple of the early fourth century BC, and the Philippeion, a circular marble building with Ionic columns and a conical roof[2](https://arxaiaolympia.gov.gr/the-archaeological-site-of-olympia/?lang=en).
## The Olympic Games
The Olympic Games were part of a religious festival held in honor of Zeus, and athletes competed to please a god or a hero[4](https://time.com/4431034/rio-olympics-ancient-history/). During the games a "sacred truce" prevailed and hostilities ceased; athletes benefiting from a three-month truce came together from all the Greek cities of the Mediterranean world, competing for the symbolic reward of an olive wreath[1](https://whc.unesco.org/en/list/517/) • [6](https://www.greekunescomonuments.gr/en/monument/archaeological-site-of-olympia/). The Olympiad, the four-year period between successive celebrations, became a chronological system of dating used throughout the Greek world[1](https://whc.unesco.org/en/list/517/).
The sports structures lay east, south, and west of the sacred precinct: the stadium and the hippodrome to the east, and the thermal baths, the [Palaestra](https://www.edgepedia.org/palaestra), and the Gymnasium to the south and west[1](https://whc.unesco.org/en/list/517/). The Palaestra, a square building with a peristyle court of the 3rd century BC, was where athletes exercised in wrestling, boxing, and jumping; the adjacent [Gymnasium](https://www.edgepedia.org/gymnasium-ancient-greece), an open space surrounded by stoas on all four sides, let athletes practice running in bad weather[2](https://arxaiaolympia.gov.gr/the-archaeological-site-of-olympia/?lang=en). The stadium is entered today through the Crypt, a vaulted roofed passage with a Hellenistic propylon constructed in Roman times[2](https://arxaiaolympia.gov.gr/the-archaeological-site-of-olympia/?lang=en).
Victors gained lasting honors: their names were engraved for eternity, they were permitted to place their statues in the sanctuary of Zeus, and at home they received privileges such as lifetime board at the prytaneum, front-row theater seats, and tax exemption[7](https://www.lemonde.fr/en/archeology/article/2024/07/30/greek-athletes-ran-and-fought-to-get-their-statues-in-zeus-sanctuary_6705406_173.html). The games were not immune to politics: according to the Princeton Encyclopedia, Sulla decided to shift the Olympic games to Rome and organized the 175th Olympiad (80 BC) there, though Olympia recovered in the time of Augustus after 31 BC[5](https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0006%3Aentry%3Dolympia).
The sanctuary also served as a stage for diplomacy. Communities across the Greek-speaking Mediterranean set up official dedications and diplomatic documents at Olympia during the Archaic and Classical periods, including a treaty between Rome and Aetolia that demonstrated the reality of Roman power in Greece in the second century BC[8](https://pages.uoregon.edu/maphist/english/EU/EU13-01.html).
## Decline and Christian settlement
The Altis was a major sanctuary from the 10th century BC to the 4th century AD, the period marked by celebration of the games from 776 BC to 393 AD[1](https://whc.unesco.org/en/list/517/). A Christian settlement survived for a time among the ruins: the workshop of Pheidias was discovered beneath the remains of a Byzantine church, and the workshop itself had been converted into an Early Christian basilica in the fifth century[1](https://whc.unesco.org/en/list/517/) • [2](https://arxaiaolympia.gov.gr/the-archaeological-site-of-olympia/?lang=en). Continuous settlement at the site was interrupted only in the 7th century AD, as a result of natural disasters[1](https://whc.unesco.org/en/list/517/).
## Excavation and rediscovery
Excavation at Olympia followed a long process of discovery. Excavation only commenced after Johann Joachim Winckelmann urged that Olympia be examined and after the Englishman Richard Chandler pinpointed where the sanctuary of Zeus stood in 1766[9](https://www.journals.uchicago.edu/doi/10.1086/722249). German excavations first began in 1875, and the work stood for innovation from the start: although excavation methods were still in their infancy, photography was already systematically used for documentation purposes[3](https://www.dainst.org/en/dai-standorte/athens/research/150-years-of-german-excavations-at-olympia).
The excavation is no longer an exclusively German project; international researchers now work alongside German scholars, and recent fieldwork in areas adjacent to the old excavation zones has shown that the sanctuary was considerably larger than previously thought, with some parts still completely unexplored[3](https://www.dainst.org/en/dai-standorte/athens/research/150-years-of-german-excavations-at-olympia). A multi-year research project starting in 2026 is planned to investigate infrastructure and resource use within the sanctuary, focusing on water management and the use of stone as a building material[3](https://www.dainst.org/en/dai-standorte/athens/research/150-years-of-german-excavations-at-olympia).
## Museums and the modern Olympic connection
Since March 24, 2004, three museum centers have operated at Olympia: the Archaeological Museum, the Museum of the History of the Olympic Games (the old Syngreion), and the Museum of the History of Excavations[10](https://ancientolympiamuseum.com/index.php/2022/09/04/history-of-the-museum/). The Archaeological Museum, within 3,500 square meters of exhibition space, tells the story of the Sanctuary of Zeus from prehistoric times to the early Christian centuries[10](https://ancientolympiamuseum.com/index.php/2022/09/04/history-of-the-museum/). Surviving masterpieces displayed there include large votive archaic bronzes, the pedimental sculptures and metopes from the temple of Zeus, and the Hermes by Praxiteles[1](https://whc.unesco.org/en/list/517/).
The site remains tied to the modern games. The revival of the Olympic Games in 1896 through the efforts of [Pierre de Coubertin](https://www.edgepedia.org/pierre-de-coubertin) drew directly on the ancient precedent[1](https://whc.unesco.org/en/list/517/), and before each modern Olympiad the [Olympic flame](https://www.edgepedia.org/olympic-flame) is lit at Olympia in a ceremony held among the ruins, before the ancient temple of Hera[11](https://apnews.com/article/f68de04bd8871d08f06c5c6c724c3bdc). Each year the archaeological site attracts hundreds of thousands of visitors[3](https://www.dainst.org/en/dai-standorte/athens/research/150-years-of-german-excavations-at-olympia).
## Protection
The property is protected under Greek Law No 3028/2002 on the Protection of Antiquities and Cultural Heritage, and the sanctuary and its surrounding landscape were designated an archaeological site in 1992 (Government Gazettes 128/B and 216/B)[1](https://whc.unesco.org/en/list/517/). The principal threats are fire and flooding: the 2007 fires that burned a great part of the Peloponnese did not affect the ancient monuments, dikes along the Alpheios protect the site from flooding, and fire-protection infrastructure is checked annually by the Ephorate of Antiquities of Eleia with the local Fire Service[1](https://whc.unesco.org/en/list/517/). Near the site, an Olympic Botanical Garden contains flora native to the area which has grown there since antiquity, following the descriptions of the ancient traveler Pausanias[1](https://whc.unesco.org/en/list/517/).
