Ancient Rome was a powerhouse of innovation, culture, and urban life, with fascinating facts that highlight its complexity and influence. Here are ten surprising facts about the city in its heyday:

1. Concrete invention: Romans developed concrete, enabling the construction of durable structures like the Pantheon and aqueducts.
2. Population peak: At its height around 100 AD, Rome had about 1 million inhabitants, making it the largest city in the world until the 19th century.
3. Gladiators were celebrities: These fighters were admired and sometimes sponsored by wealthy patrons, enjoying fame akin to modern sports stars.
4. Women’s rights: Unlike many ancient societies, Roman women could own property, run businesses, and inherit wealth.
5. Aqueducts’ capacity: Rome’s aqueduct system delivered roughly 1 million cubic meters of water daily, supporting baths, fountains, and households.
6. Road network: The Romans built over 400,000 km of roads, including 80,500 km of paved roads, facilitating trade and military movement.
7. Public baths: Bathhouses were social hubs, with some, like Baths of Caracalla, accommodating thousands daily.
8. Legal legacy: Roman law laid the groundwork for many modern legal systems worldwide.
9. Currency system: The denarius was the standard silver coin, widely used across the empire to stabilize trade.

In ancient Rome, greeting someone was simple: say "Salve" if addressing one person, or "Salvete" for multiple people. The more formal greeting was "Ave," often used in official or respectful contexts. These greetings reflect the Latin language’s influence, which remains foundational to many modern languages today.

Interestingly, the modern Italian greeting "Ciao" has a different origin. It derives from the Venetian phrase "s-ciavo," meaning "your servant," initially a polite way to say "at your service." Over time, "ciao" evolved into the casual hello and goodbye used throughout Italy and beyond.

Fun fact: "Ave" was famously used in Roman salutes, like "Ave Caesar," highlighting respect and allegiance. When visiting ancient sites such as the Pantheon or the Colosseum, using "Salve" is a pleasant nod to history.

Yes, the Colosseum is one of the New 7 Wonders of the World, voted in 2007 through a global campaign. However, it is not one of the original ancient 7 wonders. The ancient 7 wonders date back to classical antiquity and include magnificent constructions like the Great Pyramid of Giza — the only one still standing today — the Hanging Gardens of Babylon, and the Statue of Zeus at Olympia.

The New 7 Wonders list celebrates well-known sites worldwide, reflecting cultural significance and architectural achievement. Alongside the Colosseum, this list includes the Great Wall of China, Petra in Jordan, Machu Picchu in Peru, Chichen Itza in Mexico, the Taj Mahal in India, and Christ the Redeemer in Brazil.

The Colosseum remains a symbol of ancient Rome’s grandeur, hosting gladiator fights and public spectacles. To fully appreciate it, consider pre-booking your ColosseumTickets and combine your visit with the nearby Roman Forum.

Yes, the 7 hills of Rome still exist and are integral to the city's geography and history. These hills are Aventine, Caelian, Capitoline, Esquiline, Palatine, Quirinal, and Viminal. Each hill has its own character and landmarks to see today.

The Palatine Hill is where Rome’s legendary founding took place and features ruins of imperial palaces and beautiful gardens. The Capitoline Hill hosts the Capitoline Museums and the Piazza del Campidoglio, designed by Michelangelo. Aventine Hill is known for peaceful parks and the famous keyhole view of St. Peter’s Basilica.

Esquiline Hill features grand churches and the Basilica of Santa Maria Maggiore, while the Caelian Hill is quieter, with ancient churches and Roman ruins. The Quirinal Hill has the official residence of the Italian President, and the Viminal Hill houses Rome’s main train station.

A walking route connecting these hills provides an immersive way to appreciate Rome’s topography and history, starting near the Colosseum and winding through Monti and Centro Storico.

Rome holds several remarkable records that underline its cultural and historical significance. It has the most churches of any city worldwide, with over 900 houses of worship scattered across its neighborhoods. This abundance reflects its central role in Christianity and architectural heritage.

The city also contains more than 2,000 fountains, including the famous Trevi Fountain, which attracts millions of visitors who toss coins to ensure their return to Rome.
