The seven hills of Rome

the long version

"This book demonstrates the important link between the history of Rome and its geologic setting in a lively, fact-filled narrative sure to interest geology and history buffs and travelers alike. The authors point out that Rome possessed many geographic advantages over surrounding areas: proximity to a major river with access to the sea, plateaus for protection, nearby sources of building materials, and most significantly, clean drinking water from springs in the Apennines. Even the resiliency of Rome's architecture and the stability of life on its hills are underscored by the city's geologic framework."--Jacket.
