Known since time immemorial. In 1981, J. de la Vega identifies the cova del Pont Vell as a synonym of the cova dels Voliacs, a synonymy that is also recorded in the Inventari del Patrimoni Arqueològic de Catalunya, but the location it gives corresponds to the cova dels Voliacs and the description to the cova del Pont Vell, an error that is also recorded in the Catàleg Espeleològic de Catalunya of 2009. In reality these are two different cavities: the cova dels Voliacs (or cova dels Muriacs) and the cova del Pont Vell, explored by the SIE in 1970.

We had the location of the cova dels Voliacs (believing it was the cova del Pont Vell) and we quickly realised that they were different cavities.

Once the survey was done, we attempted, without success, to locate the cova del Pont Vell, which should be located about 200 metres before the cova de la Galeria del Pont Nou.

In the Inventari del Patrimoni Arqueològic de Catalunya (and also on the ICC map) two cavities appear: the forat de Tresponts (a cavity in an ascending direction that has been partially backfilled with rubble from the construction of the road) and the forat petit de Tresponts (a descending hole through which a person can enter) approximately at the place where the cova del Pont Vell should be. We suspect that when the road was remodelled, the two entrances of the cova del Pont Vell were partially covered, which would correspond to the two forats de Tresponts, but a new search on the ground will be needed to be able to confirm this.
