What is the capital city of Italy?

The capital city of Italy is Rome, which is recognized for its profound historical significance and status as a center of government. As the capital, Rome serves as the home of the Italian Parliament and various national institutions. It is known for its ancient history, being the heart of the Roman Empire, and is a city rich in cultural heritage, housing landmarks such as the Colosseum, the Vatican, and the Pantheon.

Florence, while notable for its Renaissance art and architecture, is not the capital; rather, it is in Tuscany and serves as a cultural hub. Venice, famous for its canals and unique architecture, is a significant tourist destination but does not serve as the administrative center. Milan, recognized as a fashion and economic capital, is also not the capital city of Italy. Thus, Rome stands out as the correct answer due to its political importance and historical legacy.
