"You will never see anything greater than Rome" - Horace, 17 B.C.
Rome is one of the larger European capitals for the size of the territory; by definition it is defined “Urbe” (the City), and the Eternal City.
Throughout its history spanning three millennia, Rome was the first great metropolis of humanity, the heart of one of the most important ancient civilizations, which influenced the society, culture, language, literature, art, architecture, philosophy, religion, law and customs of the following centuries. It was the capital of the Roman Empire, which extended its rule over the whole basin of the Mediterranean and much of Europe. Rome was also the capital of the Papal States, subject to the temporal power of the Popes.
It is the city with the highest concentration of historical and architectural landmarks in the world; its historic center, bounded by the perimeter of the Aurelian Walls, is a clear expression of the historical, artistic and cultural heritage of Italy and Europe, and in 1980 was listed as World Heritage Site by UNESCO.
Heart of Catholic Christendom, is the only city in the world to host a foreign state within itself, the enclave of Vatican City: for this reason it is often referred to as the Capital of Two States.
