The Colosseum Bosses are located within the Colosseum. To access them you must first be flagged by reaching a certain arena in the regular Colosseum. Then simply use their statue to enter their personal chamber. When you kill the boss and any remaining creatures, a door will appear leading back to the Colosseum drop point.
