St Paul’s Cathedral
While Westminster Abbey is the ‘House of Kings’, St Paul’s is one of the cathedrals of the people in London where Lady Diana Spencer married Prince Charles in 1981. It was built in 1710 by Sir Christopher Wren – as the first ever Protestant cathedral, Wren was instructed not to make it too ‘Catholic’; the lavish gold artwork is the result of Queen Victoria’s influence, after she complained that it was ‘most dreary, dingy and undevotional’. During World War II, Churchill famously insisted on saving St Paul’s ‘at all costs’. It was relatively safe though – its Portland stone dome can be seen from all over London, and served as a German landmark. And from its vertigo-inducing external galleries (via some 530 steps), one can see the whole of London (and the odd architectural photographer taking advantage of its view). Visitors can also climb to the base of the massive freestanding dome, called the Whispering Gallery since a whisper can be heard right on the opposite side. Those with OBEs or upwards can get married here – so only really for people who happen to be Very Important.
