Strangely, I can find no signs of evidence that Julian Andrews (UEA) ever visited the site. But he still professes: “This kind of phenomenon is quite rare in shallow waters. Most similar discoveries tend to be many hundreds and often thousands of meters deep underwater.".
So it's obviously the same? With no explanation why (or how come) : "At least 20 pillar bases were counted, all of which feature a 34 cm diameter incision, which were probably meant for wooden columns."

Coincidentally, the Greek Government is desperately keen on oil exploration in the same area.
