The Romans loved their games or fights as you wish, gladiators against gladiators and such like Pompei had  an arena for these barbaric sports too.  The amphitheatre could house up to 20,000 people on 3 different levels.   what we have found out at Pompei during the hot summer months, the spectators were protected b a type of  dark linen covering.  Adjacent to the arena you could see the great gymnasium where youngsters would work out.
    ‘MENS SANA IN CORPORE SANO’ was the roman motto which translated means ‘sound mind healthy body’…. The area (141metres x 107m) is surrounded by a high wall with 10 entries. On 3 sides it has a door to the swimming pool (35metres x 22m).
