Everyone's favourite (not-so-)hidden gem, the wall of tragic heroes in Postman's Park, has its first new memorial plaque since Edwardian times. A fresh inscription commemorates Leigh Pitt, who drowned in Thamesmead in 2007 while attempting to save a struggling child. The Watts Memorial records 47 similar acts of bravery, in flowery Victorian language - it is surely the only edifice in the world to sport the words 'dangerous entanglement of weed'. And it was, until recently, a moribund epitaph of long-lost souls. Mr Pitt becomes the first new hero since 1931 and gets the same glazed-tile treatment as his unfortunate predecessors. The Diocese of London, who approved the request by Mr Pitt's family, are open to further applications. With thanks to Caroline's Miscellany for alerting us to this laudable development.
