it pretty uch impossible to be done in there... no events are ever organized in there, no concerts no even the biggest artist nothing, there was a part of the colosseum that was even clossed to turist up to a couple of months, you actualy think they will let a loads of freetsylers in thee to play with a ball.... as much as i would love it gotta b realistic...the coloseum is never touch here for nothin....
the only arena similar to the coloseum that is used fr events in the "Arena" of Verona... but colosseum psssss nah dought it
