The Mouth of Truth in Rome is a medallion measuring approximately 175 x 175 x 19 cm and made of marble. Its age is estimated at over 2000 years.According to medieval legend, the mouth functions as a lie detector. The hands of those who lie, especially unfaithful wives, cut off the mouth. Today they are located in the vestibule of the church from the 6th – 12th centuries dedicated to the veneration of Our Lady of Greece.There is also a special place for lovers – the reliquary of the head of St. Valentine – the patron saint of all those who are sick with love. The Catholic Church remembers him on February 14.

The Mouth of Truth became popular with tourists after the premiere of the 1953 movie “Roman Holiday” with Audrey Hepburn and Gregory Peck.
