The Sacred Grove is the green area at the bottom of the famous Notre-Dame de la Garde basilica; it is one of the main garden of the city, but at the same time is considered to be (as its name says) a sacred place.  Since the Middle Age, in fact, the park has been a theatre for several processions leading to the top of the hill where there used to be a statue of the Virgin Mary.  But walks are not the only activities allowed inside the park, as it is equipped with structures such as a sports field, bowling alleys and a little garden.
