Most Blue Badge Guides, when conducting a tour of London, will give priority to what people can see. Occasionally, however, they will mention a building that has been lost to fire, bombing or development. One such is the Crystal Palace, originally found in Hyde Park.

St. Paul’s Cathedral is one of London's most famous landmarks, its majestic dome visible from many parts of the capital. This architectural masterpiece - a symbol of London’s strength and resilience - and has been the site of many historic occasions, including royal weddings and state funerals. It is a working church and a place for quiet reflection, but there are also many wonderful things to see inside on a visit. Blue Badge Tourist guide Patricia Gentry shares just a few of her favourites below.
