Cemeteries are a logical necessity in a settled population which wants a specific place to bury its dead. The three cemeteries of Mazarrón Port are planned, as much in terms of order as orientation.
The best reflection of a permanently or seasonally settled population in Mazarrón Port in the Late Roman period is the cemeteries of these times in the town.
With distinctive traits, they all respond to what at this period of time and in other areas have been called managed necropolis, given the order of the burials as the result of a rigorous order of the space over time. The model was quite standardized during Late antiquity, with burials in the decúbito supino position, with the head to the west and the feet to the east, in ordinary tombs in rows and often reused.
A first cemetery was identified close to the salting factory in Era street, from which were excavated 51 tombs dated by the excavator to the 5th century.
The study of the bone remains has allowed for the documentation of dietary deficiencies and degenerations and deformities, possibly related with fishing activities. A grand multiple tomb, where the individuals reflect a level of diet and a series of health problems different from the rest of the burials, allows for the hypothesis of a less favourable socio-economic position.
In the La Molineta hillock area there is a cemetery of the same name, the most extensive and best known of Mazarrón Port.
Separated especially from this cemetery, and together with the current San José church and San Vicente del Puerto Street, another nucleus of Late Roman tombs was excavated. This cemetery presents a collection of tombs similar to those in the La Molineta cemetery. The San Vicente street cemetery, according to the excavator, would date back to the second half of the 4th century and the first half of the 5th, given that it was recovered from a rubbish dump of the second half of the 5th and beginning of the 6th centuries.
