“La Berta” refers to the head of a woman, sticking out from the walls of the Church of Santa Maria Maggiore. Locals have given different explanations for her presence. Some say the head was petrified by an astrologer in 1326 after he was claimed to be an alchemist who could communicate with the devil. Others say it is a memorial to a greengrocer who donated the church’s bells. The most believable is that this is the head of an old Roman sculpture placed there as a decoration in the Middle Ages.
