Christopher Wren
In 1666, the Great Fire of London destroyed much of the medieval city. Wren produced ambitious plans for rebuilding the whole area. His plans were rejected, partly because property owners insisted on keeping the sites of their destroyed buildings. Wren did design 51 new city churches, including a new St Paul's Cathedral. In 1669, he was appointed surveyor of the royal works. This gave him control of all government building in the country. He was knighted in 1673.
