A Whaley Bridge priest has revealed that the Macclesfield Road site, which could be developed by house builders, used to be farmed by monks.
Father Jamie MacLeod from Whaley Hall researched the history of the threatened site in the town and joined action group Whaley Bridge Matters at their most recent meeting.
He said documents about the field, now known as C9 in proposals to go into High Peak Borough Council’s local plan, date back to 1102.
The land, which was owned by William Peveril, Lord of the High Peak, who lived at Peveril Castle at Castleton, was farmed by monks from Lenton Abbey in Nottinghamshire.
Kevin Worthington, chairman of the residents association, said: “This link adds to our reasons for urging the council to remove this site from the local plan. If the plan goes through, it would allow building there, possibly in the very near future.”
