Rome is famously known as the 'City of Seven Hills' - the Palatine, Capitoline, Quirinal, Viminal, Esquiline, Caelian, and Aventine hills. The ancient city was founded on and expanded across these seven hills along the Tiber River. This traditional geographical feature defines Rome's historic core. Thimpu (Bhutan), La Paz (Bolivia), Kathmandu (Nepal), Vienna (Austria), Berne (Switzerland) are not historically associated with the 'seven hills' designation.
