Bletchley was originally a twin-centred village: around the parish church of St Mary’s and to the south-west around the area marked as Far Bletchley.
It grew up under the Normans, along with Water Eaton. Although connected throughout several centuries by land ownership and the church, these settlements did not grow together until the present century, when they joined with Fenny Stratford.
During the development of Milton Keynes, Bletchley provided some of the early vital services. In 2001 Parish Councils were formed for all areas under Milton Keynes Council. Bletchley was considered too large to be served by a single parish council and was split into two – West Bletchley Council and Bletchley & Fenny Stratford Town Council.
