Rome is the capital and largest city of Italy and the capital of the Lazio region. Located along the Tiber River in central Italy, Rome is one of the world's oldest continuously inhabited major cities and has been a center of political power, religion, art, architecture, and culture for more than two millennia. The city is home to around 2.8 million residents within its municipal boundaries and forms the center of a much larger metropolitan area.

Rome is renowned for its extraordinary concentration of ancient and historic landmarks. The city contains the Colosseum, Roman Forum, Pantheon, Trevi Fountain, Spanish Steps, Piazza Navona, Castel Sant'Angelo, and numerous historic churches, palaces, fountains, and archaeological sites. Its historic center, together with properties associated with the Holy See, is recognized as a UNESCO World Heritage Site. Rome also completely surrounds the independent city-state of Vatican City, the headquarters of the Catholic Church and home of St. Peter's Basilica and the Vatican Museums.

The city's history stretches from its traditional founding in 753 BC through the Roman Kingdom and Roman Republic to the Roman Empire, when it became the center of one of the largest empires in history. Following the decline of the Western Roman Empire, Rome remained an important religious and cultural center before becoming the capital of the unified Kingdom of Italy in 1871. Today, remnants of its ancient past stand alongside Renaissance and Baroque architecture, modern neighborhoods, museums, restaurants, shopping districts, and busy urban streets.

Rome is one of Europe's most visited destinations, attracting millions of visitors each year for its archaeological heritage, museums, architecture, cuisine, religious significance, and cultural life. Major areas of the city include the historic Centro Storico, Trastevere, Monti, Prati, Testaccio, and EUR. The city has a Mediterranean climate with hot, generally dry summers and mild winters, while August is traditionally a quieter period as many residents leave the city for holidays.

Today, Rome serves as Italy's political and administrative center and remains a major destination for international tourism, education, fashion, film, arts, and diplomacy. Its combination of ancient ruins, Renaissance and Baroque monuments, religious heritage, lively neighborhoods, and modern city life gives Rome a distinctive character unlike almost any other city in the world.
