Pick any location and Aubrey pulls together everything the record actually holds about it:
Every location is different. Not every section appears for every place, only what the historical record actually holds turns up in a report.
Aubrey generates in-depth historical research for any location in the UK — drawing on Domesday records, scheduled monuments, Victorian OS maps, geological data and archaeological archives to tell the full story of a place.
