The undisputed symbol of Rome, the Colosseum is an awe-inspiring amphitheater that once hosted gladiatorial contests and public spectacles. Begun in 70 AD under Emperor Vespasian, this massive stone arena could hold up to 80,000 spectators. Explore its grand arches, imagine the roar of the crowds, and descend into the underground Hypogeum where gladiators and animals awaited their fate. Booking tickets online well in advance is highly recommended to avoid long queues, and consider a guided tour to truly grasp its immense history.

Adjacent to the Colosseum, the Roman Forum was the bustling heart of ancient Rome, a sprawling complex of temples, basilicas, and government buildings. Wander among the ruins of what was once the center of political, religious, and social life. Above it, Palatine Hill offers spectacular panoramic views of the Forum and the Circus Maximus, and is considered the most central of the Seven Hills of Rome, where legendary founders Romulus and Remus were said to have been found. A combined ticket with the Colosseum is standard, and comfortable shoes are a must for navigating the uneven terrain.

The smallest independent state in the world, Vatican City is the spiritual and administrative center of the Roman Catholic Church. It's home to the magnificent St. Peter's Basilica, a masterpiece of Renaissance architecture featuring Michelangelo's Pietà and a soaring dome. The Vatican Museums house an unparalleled collection of art and antiquities, culminating in the breathtaking Sistine Chapel, adorned with Michelangelo's iconic frescoes. Be prepared for large crowds and adhere to the strict dress code (shoulders and knees covered). Booking Vatican Museums tickets online is essential to save hours.

An exquisite example of Baroque artistry, the Trevi Fountain is undoubtedly Rome's most famous and stunning fountain. Commissioned by Pope Clement XII in 1732, it depicts Oceanus, god of water, riding a shell-shaped chariot pulled by sea horses. Tradition dictates that tossing a coin over your shoulder into the fountain ensures a return to Rome, a second coin finds you love, and a third leads to marriage. The fountain is best visited early in the morning or late at night to experience its magic with fewer crowds.

A marvel of ancient Roman engineering, the Pantheon is a remarkably preserved former Roman temple, now a church. Completed by Emperor Hadrian around 126 AD, its most striking feature is its massive unreinforced concrete dome, with a central opening (oculus) that lets in light and, surprisingly, rain. Standing beneath the oculus is an unforgettable experience, connecting you directly to the ancient world. Entry is free, but expect queues during peak hours, especially on weekends.

The monumental Spanish Steps (Scalinata di Trinità dei Monti) connect the Piazza di Spagna at their base with the Trinità dei Monti church at the top. Built in the 18th century, these 138 steps are a popular meeting place and a prime spot for people-watching. Adorned with blooming azaleas in spring, the steps offer picturesque views, especially from the top. While sitting on the steps is now prohibited, admiring their grandeur and the Fontana della Barcaccia below is a classic Roman experience.

One of Rome's most elegant Baroque squares, Piazza Navona is built on the site of the ancient Stadium of Domitian. Its elongated shape perfectly preserves the outline of the former stadium. The piazza is dominated by Gian Lorenzo Bernini's spectacular Fountain of Four Rivers (Fontana dei Quattro Fiumi) in its center, surrounded by two smaller fountains and grand palaces. It's a lively spot filled with street artists, portrait painters, and outdoor cafes, perfect for soaking up the Roman atmosphere.

Nestled within the beautiful Villa Borghese gardens, the Borghese Gallery is a treasure trove of art, housing an exquisite collection of sculptures by Bernini and paintings by Caravaggio, Titian, and Raphael. The villa itself was once the summer residence of Cardinal Scipione Borghese. Due to strict visitor limits, booking tickets far in advance is absolutely crucial. After your visit, explore the expansive and serene Borghese Gardens, ideal for a leisurely stroll or a boat ride on the lake.

Originally built as Emperor Hadrian's mausoleum in the 2nd century AD, Castel Sant'Angelo has served as a fortress, a papal residence, and a prison throughout its long history. Connected to Vatican City by the fortified 'Passetto di Borgo,' it offered popes an escape route in times of danger. Explore its spiral ramp, various chambers, and enjoy panoramic views of Rome and the Tiber River from its terrace, crowned by the Archangel Michael statue. The Ponte Sant'Angelo, adorned with Bernini's angel sculptures, leads directly to the castle.

Crossing the Tiber River from the city center, Trastevere offers a charming, bohemian contrast to Rome's grand monuments. This historic neighborhood is characterized by narrow, cobblestone streets, ivy-clad buildings, and traditional trattorias. By day, explore its artisan shops and hidden squares, like Piazza di Santa Maria in Trastevere with its beautiful basilica. By night, Trastevere comes alive with bustling restaurants and bars, making it a popular spot for dinner and evening strolls. It's a fantastic place to experience authentic Roman daily life and cuisine.
