Villa di Nerone

The remains of Nero's villa lie along the Aniene gorge on the road from Subiaco to its Benedictine monasteries. The imperial complex included artificial lakes formed by dams on the river; its ruins also mark the landscape in which Subiaco's monastic history began.

Why it matters

Around AD 60, Nero's engineers created the Simbruina Stagna by damming the Aniene. Ancient writers including Pliny and Frontinus described the lakes, and the name Subiaco is linked to Sublaqueum, meaning beneath the lakes. The villa's remains preserve an early layer of the valley's history. Benedict of Norcia established a monastery dedicated to St Clement on a structure associated with the complex.

What to notice

On the right bank of the Aniene, the remains include a cistern, part of the bath quarter and a nymphaeum, whose structure later supported the church of San Clemente. Roman masonry is interwoven with medieval rebuilding. Much of the complex on the opposite bank remains unexcavated. Sculptures found during nineteenth-century excavations, including the Ephebe of Subiaco and a sleeping female head, are now in Rome's Museo Nazionale Romano.

Context and history

Nero's villa extended along the gorge, reached by the Via Sublacense. Tacitus recounts that a lightning omen at a banquet contributed to Nero's decision to leave the estate. Trajan later restored the villa; the Anio Novus aqueduct used one of the lakes as a settling basin. Inscriptions indicate imperial ownership into at least the third century, after which the site declined and its materials were reused. The dams failed during the medieval period; the last is recorded as collapsing in 1305 after a flood. Excavations from 1882 to 1957 revealed scattered pavilions, including a two-storey structure with a large apsidal niche, probably a nymphaeum.
