The word "palace" comes from Old French "palais" (imperial residence), from Latin "Palātium", the name of one of the seven hills of Rome. The original "palaces" on the Palatine Hill were the seat of the imperial power while the "capitol" on the Capitoline Hill was the religious nucleus of Rome. Long after the city grew to the seven hills the Palatine remained a desirable residential area. Emperor Caesar Augustus lived there in a purposely modest house only set apart from his neighbours by the two laurel trees planted to flank the front door as a sign of triumph granted by the Senate. His descendants, especially Nero with his "Domus Aurea" (the Golden House), enlarged the building and its grounds over and over until it took up the hill top. The word "Palātium" came to mean the residence of the emperor rather than the neighbourhood on top of the hill.
