Open Garden Squares Weekend takes place in London this year with 218 hidden and little-known gardens opening to the public on Saturday 14 and Sunday 15 June. The gardens range from the historic and traditional to the new and experimental. They include classic London square gardens, roof gardens, community allotments, urban wildlife and ecology centres as well as the gardens of historic buildings, institutions, restaurants, schools and shops.

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.
