Today I visited the colloseum. I learnt that the colloseum could once  hold up to 75 thousand people. I also learnt that the main attractions there where animal fights, public executions and most of all gladiator fights. I learnt that gladiators where mostly slaves and prisoners of war trying to win there freedom. If a gladiator could survive 5 years of gladiator fights he would be set free (they fought about 2-3 fights a year).
