East Mill, Blackthorn Blackthorn · Oxfordshire · England

East Mill, Blackthorn, stands on Blackthorn Hill near Bicester. The hill had a windmill by 1809, and later nineteenth-century Ordnance Survey mapping showed two tower mills on the hill. These became known as East Mill and West Mill. East Mill was the more easterly of the pair and was a tower corn mill. Its structure was distinctive because it was tile-hung, and specialist mill records also note endless-chain winding.

The mill lost its sails and cap, but the tower survived. Later records describe the remains as standing to curb level, and modern accommodation material records the former windmill as a renovated historic tower. The site is now associated with self-catering accommodation and domestic conversion rather than milling. The surviving evidence confirms the former corn-milling use, tower-mill form, tile-hung construction, loss of sails and cap, and subsequent adaptation. No detailed owner sequence, named millers, machinery inventory, or final working date has been identified in the consulted sources.
