People in ancient Rome loved going to the baths. There were usually cold, hot and warm baths. There were public swimming pools too. They were big rooms and were usually full of people. This is where Romans went to relax and talk with their friends.
Romans also liked to watch chariot racing. The chariots had two or four wheels and were pulled by horses. The races were very exciting because they were very fast and there were lots of crashes.
One of the Romans’ favourite activities was watching gladiators fight. They fought in big stadiums like the Coliseum. Gladiators were usually prisoners or slaves who had to fight. Good gladiators became really famous but most of them were killed when they were fighting.
