The ancient city of Rome was built on seven hills, predominantly on the Palatine Hill, which is one of the most famous hills in this area. This strategic location provided natural defenses and a central point for political, social, and cultural activities. The surrounding hills offered fertile land and resources for the Roman civilization to flourish and expand. Additionally, the city's infrastructure and architecture, including iconic structures such as the Colosseum and the Roman Forum, reflect its rich historical significance and influence on Western culture.
