The colosseum was constructed in the 3rd century AD, and it's believed to have given room for as much as 30,000 spectators. It is 138 metres long by 114 metres wide. Underneath it run two passageways. This was the place where animals, prisoners and gladiators were kept, just until the moment when they were brought up into the bright daylight to perform what was in most cases the last show of their lives. One area of the walls is gone, and this was damages by 17th century ignorance, when dissidents hiding inside were driven out by the ruling Turks. A big hole was shot in the wall of the colosseum, in order to uncover their hiding places.
