This masterfully crafted colosseum sculpture was built by Ryan McNaught, a certified LEGO builder who used over 200,000 bricks to make what is arguably "the most challenging LEGO model ever created".
The piece is built with both the version from two thousand years ago and the modern version represented on either side, and it was so difficult to build that it gave Ryan a new respect for the ingenuity of Roman architecture.
Bravissimo Ryan!
