1. Burial grounds: Many of the tombs within several temple sites on Malta contain human remains or skeletal evidence suggestive of the temples' possible religious use or significance.
2. Sacred ceremonies: The orientation of various structures within the temple complexes, such as alignments with celestial bodies or certain geographic landmarks, suggests they served as sites for astrological observations, ritual celebrations, or religious activities.
3. Worship and devotional spaces: The numerous altars, stelae, and various sacred images discovered in these structures might hint at their spiritual use.
4. Observatories: Theories postulate that certain Maltese temples, due to their alignment, served as ancient astronomical observatories for monitoring and analyzing celestial movements.
5. Communal gatherings: Archaeological interpretations posit that since artifacts for everyday household tasks are scarce but evidence of ceremonial objects and communal practices is apparent, there was an emphasis on gathering in spaces like these for community ceremonies.
6. Administrative centers: While a less popular concept, some suggest temple premises held both communal and potentially administrative significance with a possible hierarchy involved in certain ritual or leadership dynamics.
Ultimately, the prehistoric nature of these temples limits absolute knowledge of their purpose, leaving ample space for various hypotheses to co-exist. Ongoing research contributes to a better understanding of these remarkable structures over time.
