Roger Worsley, from Pembrokeshire, was a prolific writer, photographer and collector with a varied range of interests. Within his rich collection are photographs of the First World War, most notably of the Western Front that feature a number of unusual prototype tanks and tracked vehicles that would alter the character of the war from 1917 onwards.

Another key area of interest are the industrial communities of Wales. The mining images, the work of pioneering photographer W.E. Jones, focus on the Pontypool area. They offer a glimpse into the lives of Welsh miners a century ago and their struggle for improved pay and conditions through the union movement. Many photographs were taken underground using a magnesium flash.

Among 50,000 of Worsley's own photographs is a set from the 1970s looking at slate mining in Gwynedd, illustrating the techniques involved and and the idiosyncratic local architecture the industry gave rise to. Perhaps most poignant are the pictures recording the closure of the quarries and the subsequent dereliction of the local community.
