I have had an interesting correspondence with Historic England and have had a couple of spreadsheets detailing different information.

I have linked these into a Fusion table:

https://www.google.com/fusiontables/DataSource?docid=14xbBg7o-h-1IY2RwKji9n3xrPyRiYyFGWS9z_AEK

Is any of this of use to Wikidata?

I can extract, massage, whatever to most formats...
