Nicholas Hawksmoor (probably 1661 – 25 March 1736) was an English architect. He was a leading figure of the English Baroque style of architecture in the late-seventeenth and early-eighteenth centuries. Hawksmoor worked alongside the principal architects of the time, Christopher Wren and John Vanbrugh, and contributed to the design of some of the most notable buildings of the period, including St Paul's Cathedral, Wren's City of London churches, Blenheim Palace and Castle Howard. Part of his work has been correctly attributed to him only relatively recently, and his influence has reached several poets and authors of the twentieth century.
