 Many churches are named after Saint Martin of Tours.St Martin-in-the-fields, at Trafalgar Square in the centre of London, has a history appropriately associated with Martin's renunciation of war; Dick Sheppard, founder of the Peace Pledge Union, was Vicar 1914–26, and there is a memorial chapel for him, with a plaque for Vera Brittain, also a noted Anglican pacifist; the steps of the church are often used for peace vigils.Saint Martin's Cathedral, in Ypres, Belgium, is dedicated to him.
