Lest We Forget: The Hidden Wartime Defences of West Wales

First published as Lest we forget in our November/December 2025 edition, Stuart Millson’s feature looks beyond the familiar story of the Blitz to the wartime landscape of West Wales. As Remembrance approaches, it asks us to notice the concrete structures that still stand beside roads, rivers and railway lines.

Millson begins with Dylan Thomas, not as the poet in a Carmarthenshire writing shed, but as a contributor to the 1944 Ministry of Information film Our Country. Thomas’s words evoke ordinary homes under blackout, aircraft moving through the night and people waiting on hillsides while war reached into everyday life.

Wales experienced that conflict directly. Cardiff, Swansea and the South Wales docks endured bombing, while communities farther west prepared for the possibility of invasion. Plans were drawn, defensive lines were built and members of the Home Guard watched the routes an advancing force might use.

Many of those preparations now blend into the scenery. A small concrete block half hidden by ivy can look like no more than a ruin in a field. Yet pillboxes were deliberately positioned to guard roads, bridges, river crossings and railways, their narrow openings arranged to give defenders a field of fire.

Defences hidden in the landscape

The national historic environment record confirms that Carmarthenshire formed part of an extensive Second World War anti-invasion system. The Rhos Llangeler stop line ran between Llangrannog and Pembrey, with branches towards Carmarthen and Llandovery. It combined pillboxes with anti-tank ditches, roadblocks, minefields and natural obstacles.

At Cynwyl Elfed, Millson draws attention to a bridge and a building whose openings face the Carmarthen road. Coflein also records a surviving semi-sunken Norcon pillbox in the village: a circular structure assembled from pre-cast concrete sections and designed to command the surrounding approach.

The original journey continues to Henllan, beside the River Teifi, where a stark concrete position overlooks the valley. These structures were practical military works, but their survival gives them another role today: they make an emergency planned more than eight decades ago suddenly visible in a quiet rural landscape.

Near Carmarthen, official records identify pillboxes beside the former Carmarthen–Fishguard railway and around Bronwydd. One at Bronwydd is a Type 24 design built to bullet-proof standard; another covered an anti-tank ditch on the western branch of the stop line.

Local memory, more than eighty years on

The article also pauses at Bronwydd’s community history sign, which depicts the local Home Guard on patrol. Men who knew the lanes, farms and river crossings were asked to imagine those familiar places as a battlefield and to wait for an invasion call that, thankfully, never came.

That is what gives these remains their power. They are neither grand monuments nor visitor attractions. They are fragments of a defensive landscape, often passed without a second glance, which connect the wider history of the Second World War with particular West Wales communities.

Millson closes with Dylan Thomas’s image of morning breaking over a country at war. Read again at Remembrance time, the feature is an invitation to look carefully, remember the people who waited and served, and recognise how much history can survive in an ordinary roadside view.

This Flashback Friday feature is republished from West Wales Life & Style, November/December 2025, pages 43–51. It has been lightly edited for the web, with surviving defences checked against Coflein, the National Monuments Record of Wales, in October 2026. Advertising and time-sensitive material from the original magazine pages have been omitted.
