Campo de' Fiori is a square in Rome near the border between rione Parione and rione Regola. The name of the square translates to "field of flowers" in the Italian language. The name refers to a time when the area was a meadow in the Middle Ages. In ancient time the square was the scene of numerous public executions and the philosopher Giordano Bruno was burned for heresy in 1600.

Today the square is one of the most well-known markets in the city with bars and nightclubs in the vicinity.
