Roman Colosseum
The symbol of the city and Rome’s most famous landmark is the Roman Colosseum. Inaugurated in the 1st century AD, over 50,000 spectators came to watch brutal fights between man and beast during its approximately 500-year life, with the last battle taking place here in 523. It’s managed to remain remarkably intact and can be toured by day or night. You might want to come twice, during the day to marvel at all the details, and after dark, when it’s illuminated against the backdrop of the night’s sky.
