It's thought that artifacts found on Creaden Head could predate the Mount Sandal settlement in Derry.
Local Historian Noel McDonagh told Eamonn Keane on Deise Today that Creaden has been settled multiple times.
"The most exciting thing about Creaden is that it has been continuously settled in," he said. "It's been settled in from the bronze age, to the late Charlie Beamish."
He said the first settlers in the area came from England via land bridge.
"England would have been joined with Doggerland onto all of Europe, so they would have come from Europe to England to Ireland."
Historian Dermot Power said there have been other significant discoveries in recent times.
"We've discovered other enclosures around Waterford that three Newgranges would fit into," he said, "we've had a discovery of an ancient monument just out by Knockeen Dolmen."
