Almost seventy years later, the Siphnian archaeologist Varvara Filippaki from Siphnos began the first systematic excavation of the acropolis of Ayios Andreas under the auspices of the Archaeological Society at Athens. From 1997 to the present day, the investigations have continued under the direction of Dr. Christina Televantou, revealing the strong Mycenaean wall in its entire extent, as well as the dense urban planning of the historical times (mid-8th to 2nd century B.C.). The works implemented in the period 2002-2008 offered Siphnos the first organized and visitable archaeological site.
