Which archaeological sites provide early evidence of Christianity in Malta?

The earliest archaeological evidence of Christianity in Malta consists of numerous collective underground burial places, commonly known as catacombs, which date from the 4th to the 8th century ce.1

While tradition holds that St. Paul, the Apostle, introduced Christianity to the islands following his shipwreck there in 60 ce, these subterranean cemeteries serve as the primary physical record of the faith's early presence in the region. These sites, which are found near the island's ancient capital, reflect a broader Mediterranean tradition of using underground rock chambers for burial.12
