Postman's Park

Based on the Wikipedia article

Postman's Park is a park in central London, a short distance north of St Paul's Cathedral. 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.

Opened in 1880 on the site of the former churchyard and burial ground of St Botolph's Aldersgate church, it expanded over the next 20 years to incorporate the adjacent burial grounds of Christ Church Greyfriars and St Leonard, Foster Lane, as well as the site of housing demolished during the widening of Little Britain in 1880, the ownership of which became the subject of a lengthy dispute between the church authorities, the General Post Office, the Treasury, and the City Parochial Foundation. The park's name reflects its popularity amongst workers from the nearby GPO's headquarters.

In 1900, the park became the location for George Frederic Watts's Memorial to Heroic Self Sacrifice, a memorial to ordinary people who died saving the lives of others and might otherwise have been forgotten, in the form of a loggia and long wall housing ceramic memorial tablets.
