The Rock was built on the site of the old Church Room. It is situated the other side of the wall opposite the Church Porch. It was built and is managed by the Ecclesiastical Charity for the use of the church and associated groups. Refreshments are regularly served there after services and it is the venue for the Mothers Union monthly meetings. It also houses a toilet suitable for all with baby changing facilities. The name was chosen from a selection put forward by the children at Thurston Primary School.
