As London continued to grow throughout the medieval period, urban development grew beyond the city walls. This expansion led to the suffix words "Without" and "Within" which denote whether an area of the City – and usually applied to the wards – fell outside or within the London Wall, though only Farringdon and (formerly) Bridge were split into separate wards this way (Bridge Without falling beyond the gates on London Bridge). Some wards – Aldersgate, Bishopsgate and Cripplegate – cover an area that was both within and outside the wall; although not split into separate wards, often the part (or "division") within the Wall is denoted (on maps, in documents, etc.) as being "within" and the part outside the Wall as being "without". Archaically "infra" (within) and "extra" (without) were also used and the terms "intramural" and "extramural" are also used to describe being within or outside the walled part of the city.
