I cannot find a central list (database?) or map of Blue plaques, which seems odd too me, and possibly I am not looking hard enough, so if someone could enlighten me, great.
The reason I would like one is it would be nice to be able to go to an area, and do a walk based on Blue Plaques.
Therefore I have thought I would like to create one for my local area.
Therefore I think I need some kind of online map, I can add them to, that eventually other people could access, and possibly a create a walking or cycling route from.
This is something I have never tried before and know nothing about.
Apparently there are also Red, Black and Green ones.
What's the point of putting the things up if they are hard to find ¯_(ツ)_/¯
Any advise appreciated, particularly if what I seek already exists
