The window tombs of the Tal-Minta Catacombs bring to mind both
Punic and
Christian traditions; it is not clear if the burials were originally Christian, or converted to Christian use at a later date. The architectural similarities between late-Punic tombs and Christian hypogea in Malta suggest that the underground burials of early Christians took on Punico-Roman traditions and gave them new significance. Although the agape table, a common feature of early Christian burials, and altar indicate that the place may have at some point been used for Christian burials, no clear
Christian iconography survives in any of the three hypogea. The discovery of other hypogea, mostly of Christian orientation, around Mqabba suggests that the area was once the location of a sizeable community. However, very few of these small hypogea survive; the closest burials are located at al Ħal Resqun,
Luqa and
Ta' Kandja. Although the site was certainly in use sometime around the 4th century AD, the lack of surviving finds makes any clear dating impossible. It is thus likewise impossible to know when the three hypogea fell into disuse. It is also unclear whether the well that was dug through one of the hypogea was placed there intentionally to use the cavities that the hypogea offered or whether it hit upon them accidentally. Certainly, the fact that they were connected to provide more water storage capabilities implies that their location was known. ==Discovery and excavation==
