The Culture Ministry announced new restoration works at Ancient Olympia on 25 September 2026, placing the archaeological site in a fresh phase of protection and visitor improvements. The projects concern the Roman Octagon, the Gymnasium and the retaining wall of the Treasuries of Mount Kronion in Olympia, Greece.
The works were announced for the archaeological site of Ancient Olympia, where the ministry says the projects are already under way. The announcement follows the completion and public opening in April 2026 of three restored monuments: the Early Christian basilica or Workshop of Pheidias, the complex of the Southern Baths and the Baths of the Leonidaion.
Restoration works begin across three parts of Ancient Olympia
The new programme includes the 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 for the retaining wall of the Treasuries of Mount Kronion. The Culture Ministry puts the combined budget at approximately EUR 4 million. Details of the three projects were reported on 25 September 2026.
At the Roman complex, planned work includes partial reconstruction of sections of masonry and vaulting, restoration of openings and the repositioning of fallen architectural members. The project also includes uncovering and protecting a mosaic floor with a new shelter, creating a visitor route and landscaping the surrounding area.
House of Nero links new work to Ancient Olympia history
The House of Nero forms part of the Southeast Baths, a complex with several building phases. The site began in the fifth century BC as a sanctuary of Hestia, while a stoa and additional areas were added in the third century BC. Between AD 65 and 67, a villa was built there for Emperor Nero during his visit to Olympia and later served as an official guesthouse.
In the early third century AD, the complex was remodelled as public baths. The Octagon became a monumental vaulted hall and the heated centre of the baths. Its surviving architectural elements, marble slabs, stone basin and ceramic features connect the current conservation work with the changing functions of this part of the sanctuary. UNESCO describes Olympia as a sanctuary in the western Peloponnese with temples, athletic buildings and remains associated with the Olympic Games.
The relationship between the new route and the ancient remains is direct: the planned access is intended to make the Octagon easier to understand while avoiding pressure on original floors and mosaics. The wider programme also aims to expand the area available for visitors, although the announcement does not specify a completion date or a temporary closure.
