Open Plaques is a service that aims to collect and document all the historical plaques and markers that can be found globally.

If we've machine-tagged your photo with something like "openplaques:id=1234", then your photo may have been linked to a plaque in Open Plaques. To see it, visit openplaques.org/plaques/1234. It would be great if you could add it to the group too!

We're also on Twitter or you can get updates on our blog.
