Hidden Norman fort revealed in Co Down
The National Trust took ownership of the land on which the imposing defensive structure sits around three years ago.
While it was known that there was a motte, a mound-style type of defensive structure built by the invading Normans in the years after 1177, little else was known about it.

“We knew it was there, but we were struggling to get a sense of the scale of this thing,” he said.
After using drones to take aerial photographs, the Trust then decided to employ a technique known as LiDar, which involves the use of lasers shone from the air and allows precise mapping of a particular area.
The images revealed an imposing structure standing eight metres (26ft) tall, surrounded by a defensive ditch some five metres (16ft) wide.

He added: “This would have been seen for miles around and was used by the Anglo-Normans as a way of consolidating their gains.”
The National Trust, with the help of volunteers, have been clearing trees from the site and hope to open it to the public in the coming weeks.
