Memorial to Heroic Self Sacrifice

The Memorial to Heroic Self Sacrifice is a public monument in Postman's Park in the City of London, commemorating ordinary people who died saving the lives of others who might otherwise have been forgotten. It was first proposed by painter and sculptor George Frederic Watts in 1887, to commemorate the Golden Jubilee of Queen Victoria.[2] The scheme was not accepted at that time, and in 1898 Watts was approached by Henry Gamble, vicar of St Botolph's Aldersgate church. Postman's Park was built on the church's former churchyard, and the church was at that time trying to raise funds to secure its future; Gamble felt that Watts's proposed memorial would raise the profile of the park. The memorial was unveiled in an unfinished state in 1900.
