"You can already smell the history above the water," Derya Can, who has set multiple free-diving records, told AFP at the underwater park's unveiling.
"Now, divers will be able to survey the underwater history."
For film maker Karakas, this history is also personal since his name Savaş (meaning "war" in Turkish) honours the Gallipoli campaign, where his grandfather was wounded.
"His hand was burnt and I was very scared when I was a child. Each time he was trying to touch me... I was looking at his hand and feeling a little bit weird," he recalled.
"When I dive, I remember this hand. The rusted steel feels like the hand burnt by shells from those ships, so it's like holding my grandfather's hand."
