Unusually dry weather has revealed the remains of a forgotten wartime settlement hidden beneath the landscape of a historic Welsh estate.

National Trust Cymru shared that this summer’s hot weather, resulting in dry grounds, has helped uncovered a hidden chapter of Llandeilo’s wartime past at Dinefwr in Carmarthenshire.

Marks revealed in the landscape by drought conditions have exposed the outlines of former Nissen huts that once stood within the historic park.

Dinefwr has a history stretching back centuries and was home to the Rhys family, descendants of the Lord Rhys, for more than 300 years, with Newton House built on the estate in 1660.

During the Second World War, when the Nissen huts were erected, the park took on a very different role to assist with the war effort.

The temporary structures played an important role during and after the war, serving first as a hospital and later as a prisoner of war camp.

The recently captured aerial image highlights features that are normally invisible at ground level. Variations in grass growth caused by the drought have revealed the footprint of the huts, providing a glimpse into a largely forgotten element of Dinefwr’s history.

In the years following the war, the Nissen huts took on a new purpose. At a time when housing was in short supply across Britain, the former military buildings were converted into homes for local families.

The settlement became known locally as ‘Tin Town’, helping to ease post-war housing pressures and supporting the community during a period of significant change.

David Thomas, Archaeologist for National Trust Cymru, said “Many people are familiar with Dinefwr’s nationally important parkland and medieval history, but these marks highlight a much more recent chapter in the site’s story.

“The huts served a range of important functions, from a wartime hospital and prisoner of war camp to much-needed housing for local families in the years after the war.

“Discoveries like this help us better understand how people adapted to the challenges of wartime and post-war life in rural Wales.”

In Wales, National Trust Cymru care for more than 46,000 hectares of countryside, 160 miles of coastline as well as castles and gardens across the country.
