The Gallery’s national strategy promotes the understanding, knowledge and appreciation of Old Master paintings throughout the UK. It is the gallery's ambition to give these paintings a major role in modern cultural life. All resources – the collection, exhibitions, staff expertise, educational activities and research resources in the library and archives – are available to museum professionals and to the wider public. Its collection belongs to the public of the United Kingdom and entry to the main collection is free of charge. It is the fifth most visited art museum in the world, after the Musée du Louvre, the Metropolitan Museum of Art, the British Museum and Tate Modern.
