Known to the local people since ancient times, who believed it was the hiding place of the thieves who attacked the pilgrims going to Montserrat along the Camí Romeu.

The first speleological visit of which we have record is the one carried out by members of the GES – CMB in June 1955, who named it Cova de Can Mimó d'Olesa and gave it 25 metres of length, as recorded in the GES activity book. Later, three members of the ERE-CEC (O. Escolà; B. Poderós and JMª Colom) visited it on 7 April 1963. According to Escolà, during the exploration they had a problem; it seems the cave was occupied by a fox and the presence of fleas was so enormous that after a while inside they had to come out in a hurry with their bodies and clothes full of these insects. It is el colmo for a biospeleologist!. By the way, in the ERE activity book the cavity was also recorded as Cova de Can Mimó, since they did not know the correct name.

A few years later (1967 or 1968) members of the SIRE – UEC Olesa were informed by people from can Mimó of the existence of the cavity and they are the ones who began to find the first archaeological remains. In 1981 an excavation campaign was carried out that catalogued the cavity as an Epicardial Neolithic sepulchral cave.
