The Cala Morell necropolis is made up of a group of fourteen artificial caves or hypogeum, all of which were used as inhospitable "collective burial places".

It has two clear phases of "occupation": one during the Bronze Age and the other during the Late Talayotic or Post-Talayotic period, which lasted until the Roman period, until the second century AD.

There are only two caves corresponding to the oldest phase: the eleventh and twelfth. These are small and oval in shape. They have the remains of an entrance corridor, built with large slabs. They correspond to a time before the beginning of the Talayotic period. On the walls of the cave, engravings from an undetermined period can be seen.

All the other caves correspond to the late Talayotic phase. In general, they are large caves. Some of them have columns and pillars that divide the space. In one of them, the entrance has two columns and a lintel carved into the rock, reminiscent of classical architecture. It is, therefore, an example of the external influences that reached Menorca during the late Talayotic or post-Talayotic period, through the Punic world. Other caves have large depressions dug into the rock in front of the façade. Although they have been called "patios", these spaces collect rainwater for irrigation and remain flooded for much of the year. It is possible that they were already excavated for this purpose, perhaps for some reason linked to funerary rituals.

Another element well represented in the Cala Morell necropolis are the so-called capades de moro. These are twenty-two oval cavities, with rounded bottoms, excavated in a 20-metre stretch of the wall of the ravine. Their function has not yet been determined, but they are undoubtedly related to the funerary world of the Talayotic communities, as they always appear very close to the vital caves.
