Plaques of London
This site now (2011) has over 3,000 plaques. Alan says "My boundaries are roughly within the M25, although the occasional person such as Sir Stanley Spencer in Cookham creeps in." He's still collecting but how many more can there be?
Plaques - The Heritage Foundation encompasses Comic Heritage, Musical Heritage, Sports Heritage and Films & TV Heritage. It has placed many plaques and these are listed on their site.
Plaques - Westminster has its own (green) plaques and this site tells you all about them.
Plaques - Pictures and information on the plaques in Soho.
Ulster History Circle
A plaque-placing organisation based in Ulster. We give them a link here not just because it's a nice site and they have honoured us with a link, but also because they provide a list of other plaque-related organisations in Britain, some being in London.
As a rule we don't collect benches but here's a site that specialises in them. There are some touching stories behind some of them. We are delighted to see Ben Weinreb's bench there.
