Certainly known since ancient times. In January 1951, on a visit to the Plana d'Ancosa by members of the GES – CMB, they claim to have explored the Cova del Mas Milà, which is possibly the same one that four years later, in April 1955, they visit again and already cite as Cova de Mas Vilà, although of these two explorations only a record remains in the GES activity book.

The first specific mention that we know of is the one provided by members of the SIS – CE Terrassa who visit and survey it in August 1976. In some archaeological works they mention it erroneously as if it were the Cova de Valldecerves and attribute to it an archaeological heritage that surely corresponds to the latter, although at the Cova de Mas Vilar it seems that excavations have also been carried out.
