Open Plaques
Open Plaques is a community-based project which catalogues, curates, and promotes commemorative plaques and historical markers (often blue and round) installed on buildings and landmarks throughout the world.
The service brings the history that plaques encapsulate to life - and to a larger audience - by building the definitive and most comprehensive resource about these historical markers.
You can browse plaques by person, place or search.
The data and resources generated by the project are free to use under a Public Domain declaration (i.e. there are no restrictions on use).
Datapulls are run on an ad-hoc basis. Plaque id numbers do not change, but very occasionally duplicate records are deleted. The fields are fairly stable, but subject to change.
As well as UK data, you can also find global plaques data here.
