Above and to the left you see St. Pauls Cathedral. The St Paul's cathedral was an old anglos saxon wooden structure built around 900. It was destroyed along with more than half of the city in the "great fire of London" in 1666. The top architect of his day Sir Christopher Wren was given the commission for over 60 new churches, lthe Chelsea Hospital, Greenwich palace, and his masterpiece, St Paul's Cathedral. By its completion about 1680 it boasted the largest dome in the world ( an Italian style later used for the Capitol in Washington). It is the burial place of many great national figures including the Duke of Wellington (victor of the battle of waterloo - the final defeat of Neapolitan) and Nelson. It was also the scene for the funeral of Sir Winston Churchill and the wedding of prince Charles and Lady Diana Spencer.
