[2] In 1860 Hugh Cholmondeley, 2nd Baron Delamere, commissioned the Chester architect John Douglas to build a church in the centre of Over, which was then a village separate from Winsford, as a memorial to his wife, Sara.

At that time Douglas was at the start of his career and was working for Lord Delamere at his house and estate at Vale Royal Abbey.

Its plan consists of a five-bay nave with a clerestory, north and south aisles, a chancel, a tower at the southwest corner, and a vestry at the northeast.

Internally there is stone panelling at the east end with an alabaster model of the Last Supper.

[3] St John's is within the Conservative Evangelical tradition of the Church of England, and it has passed resolutions to reject the ordination of women.
