Delos today is a major archaeological site. Excavations, which were begun in 1872 by the French School at Athens, are still being carried out today.
While the tiny 1.3 square mile island was believed to be inhabited since about 3,000 BC, Delos took on a new significance in the nineth century BC when people began to make pilgrimages to the island believing it to be the sacred birthplace to the gods Apollo and Artemis. By the fifth century BC not only was the island purged of all gravesites, but also a decree was issued that said no one could give birth or be buried on the sacred island.
Later in its history, Delos became an important port and center of trade and for a time there was also a thriving slave trade. Archeological evidence shows many homes, churches, baths, a theater, and some aqueducts that date between the first and sixth centuries AD. It appears, however, that Delos has been uninhabited since the eighth century.
