Until '400, Campo de' Fiori square did not exist, and in its place stood a flowery meadow and some vegetable gardens, hence the name. But, according to a legend, the square has its name from Flora, Pompeo's lover. In 1456, Pope Callistus III did pave the area as part of a project involving the whole area. This renewal meant that many important buildings were built in the area, such as the Orsini palace. The square thus became a place of passage for personalities, ambassadors and cardinals, and this brought a certain prosperity in the area. Campo de' Fiori became home to a thriving horse market, and its surroundings were built hotel, inn, and shops. The square became the center of various commercial and cultural activities. Campo de' Fiori was the place where the executions took place. Thursday, February 17, 1600 the philosopher Giordano Bruno, Dominican monk, accused of heresy was burned alive. In his memory in 1888 in this place was built a bronze monument, made by the sculptor Ettore Ferrari. Campo de' Fiori is the only historic square in Rome where there is no church.
