The art gallery has works by all of the notable Welsh artists, including landscapes by Richard Wilson and the pioneering Thomas Jones. There is a considerable body of work by John Gibson, Queen Victoria's favourite sculptor, and major paintings by Augustus John and his sister Gwen John, including the former's famous image of Dylan Thomas. Ceri Richards is well represented. The artistic output of David Jones is well represented, but seldom on display owing to the fragile nature of his works on paper. Wales's most prominent contemporary painter, Sir Kyffin Williams (1918–2006), also features in the collection.
