The Borġ in-Nadur prehistoric site, which was in use during both the Temple Period (3,600-2,500 B.C.) and the Bronze Age (2,400-700B.C.), boasts a unique location situated between two valleys with the sea to its front.

Excavated in the 1920s by eminent archaeologist Margaret Murray, the site yielded information which helped our understanding of facets of Maltese prehistory which had hitherto remained problematic, such as differences between the Temple period and the Bronze Age. The remains and the items which were retrieved during the excavations, are to this day still being analysed by researchers using techniques which were not available to archaeologists of decades past. The four apsed ‘temple’ found within the site is fronted by a large enclosed area which is unique for such buildings.
