Rome walking tour visits Piazza della Quercia where Santa Maria della Quercia [St Mary of the Oak Tree] is tucked away. Piazza della Quercia is close to the Campo de' Fiori. Piazza della Quercia is where the butchers of Rome assemble for the past 300 years on Palm Sunday to grill meats, which funds are used to provide food for the poor at Easter. Enjoy this spot on the walking tour of Rome with Maurizio Mayer My Rome walking tours.
