High Quality Content by WIKIPEDIA articles! Postman`s Park is a park in central London, a short distance north of St Paul`s Cathedral. Bordered by Little Britain, Aldersgate Street, King Edward Street, and the site of the former head office of the General Post Office (GPO), it is one of the largest parks in the City of London, the walled city which gives its name to modern London. A shortage of space for burials in London meant that corpses were often laid on the ground and covered over with soil instead of being buried, and thus Postman`s Park, built on the site of former burial grounds, is significantly elevated above the streets which surround it. It is best known as the location of the Memorial to Heroic Self Sacrifice.
