Tibur, site of Horace's Sabine Farm

At first an independent ally of Rome, Tibur allied itself with the Gauls in 361 BC. Vestiges remain of its defensive walls of this period, in opus quadrata. In 338 BC, however, Tibur was defeated and absorbed by the Romans. The city acquired Roman citizenship in 90 BC and became a resort area famed for its beauty and its copious good water, and was enriched by many Roman villas. The most famous one, of which the ruins remain, is the Villa Adriana (Hadrian's Villa). Maecenas and Augustus also had villas at Tibur, and the poet Horace had a modest villa: he and Catullus and Statius all mention Tibur in their poems. In 273, Zenobia, the captive queen of Palmyra, was assigned a residence here by the Emperor Aurelian. The 2nd-century temples of Hercules Victor is currently in the process of being excavated.
