Which Is Older: The Colosseum, Leaning Tower of Pisa, or Venice?

When comparing the ages of three iconic Italian landmarks, the Colosseum stands as the undisputed elder. This ancient amphitheater was constructed in the 1st century AD, during the height of the Roman Empire. The city of Venice traces its origins to the 5th century AD, when refugees fleeing barbarian invasions settled on the lagoon islands. The Leaning Tower of Pisa is the youngest of the trio, with construction beginning in the 12th century AD as a freestanding bell tower for Pisa's cathedral.

So in chronological order: the Colosseum (1st century AD), followed by Venice (5th century AD), with the Leaning Tower of Pisa bringing up the rear (12th century AD). Each represents a different era of Italian history—from imperial Rome through the early Middle Ages to the medieval maritime republics.
