Chrishall is said by some to be the first place in Essex where Christianity took hold: in the Domesday Book the name of the village is stated as 'Cristehalla', meaning the home of Christ. The Holy Trinity is a large aisled church in the Perpendicular style. During the rebuilding period of the 13th and 14th centuries, a north transept was added, only to be replaced in the 15th century by the present north and south transepts. A north porch was added in the 15th century. Between 1867- 69, the two clerestory walls, the chancel arch, its piers and parapets, and the north porch were completely rebuilt, the latter being ‘in a ruinous state’. The roofs of the nave and south aisle were also completely replaced. In 1878, the vestry was added on the north side, destroying the middle window of the chancel north wall. A new reredos and the organ were added in 1889. The robust tower, constructed in flint in the Norman style, was restored in 1914 and contains a peal of six bells, the oldest of which date back to 162. It is believed that a much earlier Saxon church once existed here. There are the remains of a medieval Motte in the woods within 100 yards of the church, an indication that in the past the village might have been located nearer to the Church than it is at present.
