Amgueddfa Cymru – National Museum Wales has the largest public art collection in Wales, most of which is at the National Museum in Cardiff. The displays there contain Welsh, British and European paintings from the Renaissance to the present day, ranging from Tudor portraits and the French Impressionists to cutting-edge contemporary art. The National Museum received its Royal Charter in 1907 as a museum of natural science, archaeology, history and the arts. The range and quality of the paintings collection was transformed in 1951 and 1963, through the legacy of industrial heiresses Gwendoline and Margaret Davies. Their bequests of Impressionist and early twentieth-century British art find few rivals in the UK. Today the collection continues to develop with the support of the Welsh Assembly Government, charities, and many generous private donors. The purchase of modern and contemporary art is especially active thanks to the Derek Williams Trust. Some of the Museum’s most outstanding paintings include van de Cappelle’s ‘A Calm’, Renoir’s ‘La Parisienne’ and Francis Bacon’s ‘Study for a Self Portrait’.
