We do not know whether the data provided by Dofí Soler de Lluçars to Josep de la Vega were erroneous or whether perhaps he did not know how to interpret them. The fact is that Josep de la Vega surveyed and published them as “Balmes de Gramanet (Tòrrec)” in his “Aplec de documents arqueològics de les coves del Montsec i llur projecció a les comarques i serres properes”.

On 31 January 1993 Joan Reig, Gener Aymamí and Eliseo Peidró visited them without drawing further conclusions. In October of the following year, Gener Aymamí, E. Peidró, J. Tarrats, J. Sansalvadó, E. Tomàs and J. Reig tried to reach Gramenet from Comiols by descending through Montadó; once they arrived at the balma de Gramenet, they realised that the information they had did not correspond to this rock shelter, but to the one visited the previous year. They returned again to the rock shelter located in the barranc de la Font Freda to verify the information and then went to the village of Tòrrec to seek more information about this rock shelter. It so happened that at that moment in the square they were preparing the main festival and practically all the inhabitants were there (1991 census, 33 inhabitants), with relatives and friends. With general assent they gave it the name “Cova de l'Hereu” with reference to a nearby farmhouse now demolished.
