What is the main reason that Rome was built on hills

Answer 1

The main reason that Rome was built on hills was for strategic and defensive purposes. The hills provided a natural advantage, allowing the ancient Romans to defend against potential invaders. Additionally, building on hills made it easier to establish a fortified city with good visibility, making it more difficult for enemies to approach unnoticed. The seven hills of Rome, including the Palatine Hill, Capitoline Hill, and Aventine Hill, also provided a natural barrier against flooding from the Tiber River.
