The Imperial Villa of Vicarello was an ancient Roman villa that belonged to the emperors starting from Domitian (r.81-96). It is situated close to the north shore of Lake Bracciano and near the village of Vicarello and the modern town of Trevignano Romano.
The current private Vicarello estate is a park of about 2000 hectares in which the Roman remains of the villa and associated monumental baths were discovered in the 19th century, some of which are still preserved. The two main ancient centres are: the village which includes the now-disused 17th century Villa Valadier overlooking the lake, built on the remains of the Roman villa or vicus (village).
