"Aldersgate Without" was, at an early date, part of an area outside the northern wall called the Soke of Cripplegate, held by the church of St. Martin's Le Grand. The "Without" division was coterminous with that part of the Ancient Parish of St Botolph Without Aldersgate that was part of the City. The area included the parish church of St Botolph's Aldersgate and the adjacent Postman's Park, named after the former principal sorting office in King Edward Street, and the location of the Memorial to Heroic Self Sacrifice.
