The Colosseum

The Colosseum was a World I structure built by UnPhair near New Rome. It is arguably one of the more structurally impressive builds on World I, as it is massive. Originally, the whole Colosseum was made out of cobblestone, but after the cobble had been placed, UnPhair changed it all to regular stone via worldedit. UnPhair had initially had plans for a full interior of the Colosseum, however only the outside shell was ever made.
