The Queen Elizabeth Hall, Purcell Room and Hayward Gallery on the South Bank are now closed, preparing for a two-year refurbishment, and will re-open in 2017, which is exactly 50 years since they first opened in 1967-8. They are immune from listing status, unlike the Festival Hall, which is Grade 1 and the National Theatre is Grade 2 listed.

St Paul’s Cathedral is often second choice when it comes to competing against Westminster Abbey. Visitors to London, inquisitive to know about the traditions of royalty, are not going to want to see celebrities of earlier times unless it is Churchill, Lady Diana’s wedding or Margaret Thatcher. For most Americans, the American Chapel is the draw – they are patriotic and that is the bait on the hook!
