Colosseum, Italy

The construction of the Colosseum, one of Rome's most iconic structures, began in 72BC with Emperor Vespasian and was completed by his heir Titus. The largest amphitheater ever built, it could accommodate up to 80,000 spectators for gladiatorial contests, theater, and public spectacles. To simulate sea battles, the floor could even be flooded. The architects' designs for getting large crowds in and out quickly are still used as the foundation for modern stadiums. It's a must-see for fans of ancient Rome and Russell Crowe alike, as it's one of the most famous ancient Roman structures.

The iconic building, constructed of concrete and stone, began construction around 72AD and was completed in 80AD. Many modern-day stadiums have been inspired by the design and shape of the Colosseum. It is now one of the most popular tourist attractions in Rome, attracting thousands of visitors each year.
