Trench Green is a hamlet in Oxfordshire about 1miles northeast of the village of Mapledurham and about 4miles northwest of Reading in neighbouring Berkshire. It is situated on the rural road from Caversham to Goring Heath and Goring-on-Thames, at its junction with the access lane to Mapledurham village.[1] For local government purposes Trench Green is in Mapledurham civil parish, which forms part of the district of South Oxfordshire within the county of Oxfordshire. It is within the Henley constituency of the United Kingdom Parliament. Prior to Brexit in 2020, the village was represented by the South East England constituency in the European Parliament.[1] [2] Although barely more than a few houses around the road junction, Trench Green does contain a former school, which is now a house, and the parish's parish hall.
