Ever since Roman times, the rich and powerful have built villas in the hills surrounding Rome to escape the summer’s heat. Some, like Hadrian’s villa at Tivoli, still survive. Others, like Castel Gandolfo, built in the 17th century for Pope Urban VIII as a summer palace, were built on top of Roman villa sites. And why not? The land was already levelled and useful top quality building material was there for the taking.
