A group of vandals were reportedly spotted defacing the historic gun emplacements at Lavernock Battery yesterday (Sunday 28 Feb).

Local resident Stephen Cripps, who regularly walks his dog in the Lavernock Point Nature Reserve, took a picture of two of them as they admired their work.

He said the group numbered "at least three" others just out of shot.

"I'm on my own with the dog or I'd confront them," he said. "Makes my blood boil to see them doing this to an historical site."

Stephen told Nub News that he contacted the police who recorded the incident.

The site was built on the recommendations of the 1860 Royal Commission during the late 1860s to protect the ports of the Severn Estuary.

The concrete remains were an anti-aircraft battery built during WWII.

There were four 3.7" anti-guns arranged in a clover-leaf pattern with a lighter, 40mm Bofors gun nearby.

There was also a command post, a magazine and a workshop.

The crew slept in huts which have now vanished.

Many similar batteries were built during the war, but few remain.

Nub News is awaiting a comment from South Wales Police.
