Question

Of the thousand buildings from around the world and across history documented at GreatBuildings.com, which building has the consistently most-visited building page, and how old is the building?

Answer

As reported over time on the Greatest Hits page at GreatBuildings.com, the long-term most-visited building page is that of the Roman Colosseum, although for years after September 11, 2001, the most visted page was for the twin towers of the World Trade Center, which is still the next-most-oftenly-visited page.

The Roman Colosseum is now about 1925 years old.
