Inigo (or Íñigo) Jones (15 July 1573 – 21 June 1652) is the first significant British architect of the modern period, and the first to employ Vitruvian rules of proportion and symmetry in his buildings. He left his mark on London by single buildings, such as the Banqueting House, Whitehall, and in area design for Covent Garden square which became a model for future developments in the West End. He made major contributions to stage design by his work as theatrical designer for several dozen masques, most by royal command and many in collaboration with Ben Jonson.
