Villa of Nero, Roman villa in Ancient Olympia, Greece.

The Villa of Nero is a Roman residential structure in Ancient Olympia with visible foundations, water systems, and architectural remains from the Roman period. The site displays typical features of a wealthy Roman residence from the first century.

Nero had the 211th Olympiad moved forward two years, to 67 AD, to coincide with his stay, and built the villa over earlier structures, including a possible 5th-century BC temple of Hestia. It later served as a mansio, an official guesthouse. The present building dates from the 3rd century AD, when it was remodelled into the public Southeastern Baths, centred on an octagonal vaulted caldarium.

The villa demonstrates how Roman building methods became adopted in Greece and influenced local construction traditions. Visitors can observe today how both cultures coexist within the remaining foundations and physical structures.

The site lies within the larger Archaeological Complex of Olympia and remains accessible throughout the year. Visitors should wear comfortable shoes since the paths through the excavation area are uneven and often lack shade.

Excavations revealed an advanced water supply system with lead pipes inscribed with Roman markings, demonstrating engineering skill in distant territories. Such technical systems were uncommon in this region and period, showing the wealth of the owner.
