Volubilis

Near Meknes lies the ruin of an old Roman city, Volubilis. This outlying imperial post was ransacked for its marble in recent centuries, but much of it was left untouched. It is now being restored and has been listed by UNESCO as World Heritage. The archaeologists say they've only uncovered about half of it. The city at its peak apparently housed about 20,000 people, and is still surrounded by vineyards and lush green olive groves.
