Ancient Olympia began a new restoration phase on 25 September 2026, as the Greek Ministry of Culture advanced works across the archaeological site in Olympia. The programme covers the House of Nero, the Gymnasium and the retaining wall of the Treasuries of Mount Kronion.
The announcement gives travellers a current reason to follow the site beyond its ancient monuments: parts of the sanctuary are being protected and prepared for safer, more accessible presentation while the wider archaeological landscape remains the setting for a continuing conservation programme.
Ancient Olympia starts three restoration projects on 25 September
The Ministry of Culture’s programme includes restoration and presentation of the Roman Octagon, also called the House of Nero, the third phase of excavation and presentation at the Gymnasium, and protection and restoration of the retaining wall on the terrace of the Treasuries of Mount Kronion. The ministry’s announcement was reported on 25 September 2026 by the restoration programme.
The House of Nero is the most detailed part of the new phase. Planned work includes partial reconstruction of masonry and vaulting, restoration of openings, and the repositioning of fallen architectural elements. A new shelter is intended to protect the mosaic floor, while a visitor route and landscaping are planned around the monument.
The project is not presented as a closure of the archaeological site. Instead, the stated aim is to protect authentic remains while creating safe access and a route that does not place unnecessary pressure on original floors, mosaics or restored fabric. The announcement does not provide a completion date for the works.
The House of Nero connects Roman history with the sanctuary
The House of Nero forms part of the Southeast Baths complex, where successive building phases record changes in the use of the site. The area began as a sanctuary of Hestia in the fifth century BC, with a stoa and additional spaces added in the third century BC.
Between AD 65 and 67, a villa was built for Emperor Nero’s visit to Olympia and later served as an official guesthouse. In the early third century AD, the complex became public baths. The Octagon, a monumental vaulted hall, was the heated central space, and the baths reused parts of the earlier villa.
That sequence gives the current work a specific connection to the place: the planned protection of the mosaic and the new route concern a monument that preserves several layers of Roman-period development within the sanctuary. Three other restored monuments - the early Christian basilica or Workshop of Pheidias, the Southern Baths and the Baths of the Leonidaion - were opened to the public in April 2026.
The archaeological site stands in a valley of the Peloponnese at the confluence of the Alpheios and Kladeos rivers. UNESCO describes the sanctuary as a place with remains of temples and the sporting structures used for the ancient Olympic Games; it was inscribed on the World Heritage List in 1989, as recorded by the UNESCO World Heritage listing.
