It's a replica of sorts of the Coliseum in Rome, Italy. After making it, I added a gladiator room underneath, shown in the picture (well not yet), where you can either press buttons to open up the floor on either side allowing human gladiator fights or I have a plugin, MobArena installed in which you choose your class then click an iron block to start a game of any number of players fighting waves of mobs in order to recieve prizes. Also I am always looking for new projects so any suggestions are welcomed.
