The stone-built Holy Trinity Church in Walton opened in 1845 to provide a local place of worship for the farm labourers who lived in the hamlet, and canal workers from the newly built 1814 Aylesbury arm of the Grand Union canal. A hall was built in 1859 next door to the church to start what was to become Walton Holy Trinity National School (now Walton Hall) to support and educate local children. Walton Hall has always been both independent from and also supported by members of Holy Trinity and has been a focus of local community life from its beginnings in 1859.
