Known since remote times. The first reference we know of is by Faura i Sans (1911), who mentions la Casa Santa in the summary of an excursion in August 1910 through the Organyà area together with the biospeleologists Jeannel and Racovitza. They do not visit it, but he gives the information that had been provided to him by Ceferí Rocafort, a native of la Pobla de Segur and member of the CEC.

It is not until April 1964 that, in an “extension” of the Operació Solsonès, speleologists from different groups visit the Cabó area and among the cavities visited they cite the Cova de la Casa Santa, saying only that it is a small cavity (Escolà, 1977).

At the end of 1965, in a monographic work on the Boumort (Senent i Victoria, 1965) they mention these explorations without giving data but they add to the work a so-called Cova Santa, but giving only an approximate location that comes close to that of the Casa Santa.

In the Catàleg Espeleològic de Catalunya (Borràs; Miñarro; Talavera, 1978) only the latter appears.

In a hiking guide to the Boumort (Cortès, 2005) the Casa Santa is cited and a fairly precise location is given but with practically no further detail.

In the Catàleg Espeleològic de Catalunya (de Valles, 2009) both are listed, practically without concrete data.

At present we are practically certain that both toponyms refer to a single cavity, the Cova de la Casa Santa.

On the ICGC map, in this same area a toponym is cited: Pou de la Casa Santa, which we are completely unaware of what it refers to.
