Between 1749 and 1753, on the eve of the Lisbon Earthquake, the demolition of some modest houses to build a new building on the site led to the discovery of several Roman architectural remains (including two

Ionic order

column bases and

capital) and five epigraphic monuments. One of these, of funerary character, was lost. Among the four gravestones that reached the present, three were votive - two consecrations to

Cybele and another to Mercury-, and one was honorific (a pedestal wherein

Felicitas Iulia Olisipo honours an illustrious figure). The pieces are embedded into the wall of the building in Largo da Madalena 1-6 that leads to Travessa do Almada, where they can be observed. The architectural elements, discovered and then lost, and the two epigraphs dedicated to

Cybele support the hypothesis that there was a temple, on the location or nearby, dedicated to the goddess. However, this was never proved archaeologically. Furthermore, this doesn't consider the appearance, in the same location and circumstances, of a monument dedicated to

Mercury, the honorific pedestal and even the lost funerary epigraph, which wouldn't be related with the hypothetical temple.
