The barn is in the middle of a field just north of the A417 in East Hendred, behind a new housing development.

Oxford Mail:

One resident of the new estate, who asked not to be named, said that there is one large, locked barn in the centre of the field, and one open-sided barn used to store hay.

He said children often played in and around the barns.

One eyewitness in the area has said she thought she could see paramedics treating a patient in the field.

The path leading up to the barns is a public footpath which leads to nearby Steventon, and is regularly used by people to get between the villages.
