“My National Gallery”, a new Exhibition on Screen film created in celebration of the bicentenary of the National Gallery, London, is being shown at the Drill Hall Chepstow on Thursday 13 June, 7.30pm. The National Gallery of London is one of the world’s greatest art galleries. It is full of famous masterpieces, an endless resource of history, an endless source of stories. But whose stories are told? Which art has the most impact and on whom? The power of great art lies in its ability to communicate with anyone, no matter their art historical knowledge, their background, their beliefs.
