In November 2009 the Inspectorate team of Underwater Antiquities, conducted underwater preliminary research near the eastern coast of Polyegos island to document the location of an ancient shipwreck indicated by sponge divers from Kalymnos island.
The wreck probably dates from the late 5th to mid-4th century b.C. The ship was of medium size and was full of amphorae. Four of them were hauled without any damage , plus two table jars.
Even more , five lead cores of wooden anchors were found.
The wreck was captured and imprinted photographically and was filmed . A second research is planned for 2010 and the wreck is forwarded to be declared as Marine archaeological site.
It is believed that the wreck will provide information on the stylistic evolution of amphorae and the maritime trade routes of the classical era.
