Constructed in 1870 by George Gilbert Scott, RA, this structure was built to replace an earlier church from 1692, which stood on a medieval site adjacent to Highclere Castle. The design consists of a chancel with two bays and a nave with three bays, accompanied by a southern aisle. A porch was later added to the northern side, along with a tower to the north of the chancel. The architectural style leans towards Early English, featuring plate tracery.

​

The steep tile roof is adorned with scalloped bands above the chancel. The walls are made of flint with stone dressings and corner buttresses that are stepped and coupled. The chancel and west wall have a cill band, and the windows are generally lancet-shaped, with some featuring quatrefoils or hoodmould. The east gable is embellished with a wheel window above an intricate blind arcade, while the west gable has a circular opening above two tall lancets. The tower is topped with a shingled broach spire and a bell stage with triple lancets, with coupled stepped buttresses at each corner underneath this level.

​

Inside, the design is simple: pointed and moulded arches, Early English caps on two octagonal columns, and detached columns within the chancel windows' arcades. There are several monuments from the old church, including a detailed Jacobean Tomb for Richard Kingsmill, featuring a recumbent effigy, kneelers, and lettered panels within a Corinthian Order. The chancel houses the monument of Robert Sawyer from 1692, with a classical black and mottled white marble frame, Corinthian pilasters, swags around a pedestal, a sarcophagus base, floral ornamentation, and a top urn. A wall monument dedicated to the Bishop of Waterford from 1773 features a figure by Roubiliac. There are also two oval wall plaques for William (1799) and Mary (1783) Coleman, and other classical wall monuments from 1720, 1740, 1915, and 1933.
