@Setanta,
We've a couple of those "villa rustica" (correct plural:
villae rusticae) here in Germany. (One, the
Villa Borg, had been discovered 100 years ago, untouched for 1600 years as well)
The remains of a Roman
villa urbana can be found east of the Maltese Castle in This country residence of a large landowner in Mediterranean style covered 5.5 hectares and was built around 30 AD, remaining intact until around 275 AD.
In Xanten (
Colonia Ulpia Traiana, now one of the largest archaeological open air museums in the world) we've just one "better villa rustica" but dozens of "strip-houses" (kind of Roman terraced houses in the Gallo-Germanic provinces).
