10 Must-See Historical Sites in Rome You Can't Miss

Rome is an open-air museum where ancient history and modern life collide on every street corner. To truly experience the Eternal City, you must visit the Colosseum, the Roman Forum, and the Pantheon, which serve as the anchors of Western civilization's architectural and political heritage. Navigating these sprawling ruins effectively requires a blend of historical context and reliable mobile data to manage digital tickets and live maps.

1. The Colosseum (Flavian Amphitheatre)

No trip to Rome is complete without standing before the Colosseum. Completed in 80 AD, this massive amphitheater could hold up to 80,000 spectators who gathered to watch gladiatorial contests, mock sea battles, and animal hunts. When visiting, it is essential to book your tickets weeks in advance.

Inside the thick stone walls, mobile signals can sometimes struggle. However, with a local 5G connection from networks like TIM or Iliad, you can usually maintain a signal near the arches to upload your photos. If you are traveling through multiple countries on a Eurail pass, a EuroHop eSIM provides a single QR code that keeps you connected here and across 30+ other European nations, including the UK and Switzerland.

2. The Roman Forum

Located just a few steps from the Colosseum, the Roman Forum was the social, political, and commercial heart of the Roman Empire. Walking down the Via Sacra, you will see the remains of the Curia (Senate House), the Temple of Vesta, and the Arch of Titus.

Because the Forum is a vast outdoor space with limited signage, many travelers use audio guide apps. This makes having a robust data plan vital. Since our plans are data-only, you won't have a local phone number, but you can use WhatsApp or FaceTime calls to coordinate with travel partners without missing a beat.

3. The Pantheon

The Pantheon is arguably the best-preserved building from ancient Rome. Originally built as a temple to all gods, its most famous feature is the massive unreinforced concrete dome with a central opening called the oculus. Even after 2,000 years, it remains a marvel of engineering.

Connectivity in the Piazza della Rotonda is generally excellent. Before you enter, you might want to see plans to ensure you have enough data to research the history of the emperors buried within, such as Raphael and Vittorio Emanuele II.

4. Palatine Hill

According to legend, this is where Romulus founded the city. Today, it houses the ruins of imperial palaces. It offers the best views overlooking the Roman Forum and the Circus Maximus. The uphill trek can be tiring, so use your data to check the nearest water fountain (nasone) locations on a digital map.

5. Castel Sant'Angelo

Originally commissioned by Emperor Hadrian as a mausoleum for himself and his family, this drum-shaped building was later used by the popes as a fortress and castle. It is connected to St. Peter's Basilica by a fortified corridor called the Passetto di Borgo. For those following an Exploring Switzerland by Train: A Complete Itinerary, Rome is often a primary stop before heading north toward the Alps.

6. The Baths of Caracalla

These are not just old swimming pools; they were a massive leisure complex that could house 1,600 bathers at a time. The scale of the brickwork is staggering. Because this site is slightly removed from the main tourist cluster, having a working GPS is helpful for finding the right bus or tram.

7. The Appian Way (Via Appia Antica)

For a break from the city crowds, head to the Appian Way. This ancient highway is lined with catacombs and tombs. It is a prime example of where rural coverage matters. In Italy, we use the TIM, Iliad, and Wind networks to ensure that even as you walk the ancient stones outside the city center, you stay connected. You can see plans that offer high-speed 5G to keep your maps running in these quieter areas.

8. Largo di Torre Argentina

This sunken square contains the remains of four Republican temples and the ruins of Pompey’s Theatre, where Julius Caesar was assassinated. Today, it is also famous for being a sanctuary for Rome’s stray cats. It is a quick but fascinating stop in the middle of a busy shopping district.

9. Circus Maximus

Once the premier venue for chariot racing, the Circus Maximus could once hold 150,000 people. Today, it is a public park. It is a great place for a picnic while you look up at the ruins of the Palatine Hill. If your journey takes you toward London next, you might find that the Roman history here connects deeply with the 7 British Museum Highlights You Can't Miss.

10. Ara Pacis (Altar of Peace)

This intricately carved altar was built to celebrate the peace established by Emperor Augustus. It is now housed in a modern museum designed by Richard Meier. The contrast between the ancient marble and the glass-and-steel building is a photographer's dream.

Staying Connected: Why eSIM Beats Roaming

Most American travelers are used to the $10 per day international passes offered by major US carriers. Over a two-week trip to Italy and neighboring countries like France (dest:fr) or Spain (dest:es), those costs add up quickly. EuroHop eSIM offers a more flexible alternative with fixed data buckets or daily passes that significantly undercut those daily roaming fees.

Local Carrier Coverage in Rome

In Rome, 5G is the standard. We partner with the top three providers to give you the best possible experience:

• TIM: Excellent nationwide coverage and very strong 5G in Rome's historic center.
• Iliad: Known for high speeds and modern infrastructure.
• Wind: Great reliability, especially if you venture into the suburbs or toward the coast.
