Prolonged dry weather throws up more hidden treasures

A mysterious outline of what could have been a moated site dating back to the 13th century has been discovered in Dunderry as Ireland's recent prolonged dry spell continues to show up ancient hidden treasures. 
Local resident Ian O'Brien was flying his drone above lands to survey roadworks being carried out when he spotted the square structure in a neighbour’s field.
“I put my drone up last week to take a few snaps of our lane being tarred but this outline in my neighbour's field caught my eye. I couldn't believe it, I have flown the drone over this field a thousand times before and saw nothing. I did a small bit of research and it seems that it might have been a moated site from the 13th or 14th century, but that's not confirmed. Only for the drought I would never have seen it.

“I had sent an email to the National Monuments Service but only found out there are forms to be filled out etc to notify them which I intend doing this week.”
The unprecedented dry spell has played an unexpected role in uncovering major archaeological discoveries in Meath in recent weeks.
The international media spotlight fell on the county three weeks ago when historian and author Anthony Murphy, who has been recording and writing about the Boyne Valley for many years, used a drone along with his friend Ken Williams to reveal a large prehistoric enclosure close to the Newgrange passage tomb. 

The henge, which could measure up to 200m in diameter, is believed to have been built some 500 years after Newgrange which dates from 3,000BC.
Also at Newgrange the first research excavations at the site in more than 30 years were started under the leadership of DCU medieval historian and archaeologist Dr Matthew Stout and his wife, Boyne Valley archaeologist Dr Geraldine Stout. 
Archaeological research by the agri-technology company Devenish and UCD School of Archaeology unearthed a significant passage tomb cemetery beside Dowth Hall. The excavation has uncovered a new and significant passage tomb cemetery dating back some 5,500 years.
And finally, what's believed to be the outline of the home of St Oliver 
Plunkett was allegedly revealed by the extreme dry weather at Loughcrew in Oldcastle two weeks ago.
