The Hundred Parishes is an area of the East of England with no formal recognition or status, albeit that the concept has the blessing of county and district authorities. It encompasses around 450 square miles (1,100 square kilometres) of northwest Essex, northeast Hertfordshire and southern Cambridgeshire. The area comprises just over 100 administrative parishes, hence its name. It contains over 6,000 listed buildings and many conservation areas,[1][2][3][4] village greens, ancient hedgerows, protected features and a historical pattern of small rural settlements in close proximity to one another.
