Your picture focus on the London Open House event (pages 16-17, 5 October reminded me that the NHS has a large capital stock of buildings with much history to tell.

Apart from the few hospitals which employ archivists or have museums (Royal London, Bart's, Guy's and St Thomas') I wonder - with modernisation and closure of many older hospitals and health centres - how much of this lies undocumented? Many artefacts and collectibles risk being lost.

The NHS plan heralds the biggest NHS building programme to date. Should we also be celebrating the NHS's rich cultural heritage, and building an archive for future generations?
