Seven hills is Rome. I should explain the city was built on seven hills. Oh, and I believe the rock is St. Peter. I also found this - in the early Roman empire, traitors and criminals were thrown to their deaths from the Tarpeian Rock.

"TARPEIAN ROCK (RUPE TARPEA) IS A steep cliff located on the southern side of the Capitoline Hill, just above the Roman Forum. For centuries, the location was used an an execution sites. People who had been convicted of crimes were thrown from the 80 foot (25-meter) cliff ledge down to the Forum below. This method of execution carried a stigma of shame and was considered a fate worse than death. It was reserved as punishment for crimes that were considered especially heinous: treason, murder, and perjury."
