How did they get the stones up so high in the coliseum?

The stones used in the construction of the Colosseum were likely transported using a combination of ramps and levers, as well as manpower. Workers would have dragged the stones up wooden ramps or constructed temporary scaffolding to reach higher levels. Additionally, cranes powered by human or animal labor may have been employed to lift heavier blocks into place. This ingenuity in engineering allowed the Romans to complete such an impressive structure.
