The Forum Holitorium is an archaeological area of Rome, on the slopes of the Capitoline Hill. It was "oddly located" outside the Porta Carmentalis in the Campus Martius, crowded between the Forum Boarium and buildings located in the Circus Flaminius.
In ancient times it was the fruit and vegetable market, while the area of the adjacent Forum Boarium served as meat market. It also included a sacred area with three small temples dedicated to Janus, Spes and Juno Sospita.
