Trinity Church, High Street, Jedburgh

Trinity Church, located on High Street in Jedburgh, dates to 1818, with church offices added in 1899 by James Pearson Alison. The church is a two-story, five-bay, symmetrical building designed in an Italianate palazzo style. It is constructed of cream sandstone rubble with ashlar dressings and a coursed, stugged ashlar facade. The windows are round-headed and have cills.

The front (southeast) elevation is two stories with regular fenestration, with the outer bays advanced as pavilions. The central three bays at ground level are faced in polished ashlar, featuring a central door with a rectangular fanlight. A three-bay Tuscan screen with an entablature sits between the pavilions, which have engaged half-columns. Inner return walls of the pavilions provide access to a vestibule. A cill course runs along the first floor. A moulded cornice with rectangular panels sits above the central (inscribed "1818") and outer bays. To the left is a small, single-story, polished ashlar polygonal link providing access to a hall and church offices. The northeast and southwest elevations feature three bays grouped towards the rear, providing light to the main hall of the church; the northeast side has a blocked door at ground level to the front. The northwest (rear) elevation has two taller windows grouped to the centre, with a door at ground level to the left. A corrugated iron-roofed hut is attached at the centre, likely a former heating chamber.

The church features stained glass leaded windows by Kemp Benson & Co, Glasgow, dating to 1902. It has a steep piended roof covered in grey slates.

Inside, a single-story vestibule has stairs at either end, with handsome marble memorial tablets above the doors dedicated to Alexander Shanks and Peter Young, and William Nicol, all past ministers. A brass plaque near the door commemorates Richard Cameron, brought from a demolished Free Church. The main hall has a flat ceiling and a banked gallery running around three sides, supported by square, moulded timber columns. Deal tongue and groove panelling and seating were added by J.P. Alison in 1896. A clock is centrally positioned on the gallery, facing the organ. A two-stage pulpit and communion table stand on a raised dais in front of the organ, all probably designed by Alison. A carved timber octagonal font with a marble basin is present, originally from Boston Church.

The church offices, also designed by J.P. Alison in 1899, are a tall, single-story, symmetrical, three-bay building of stugged cream ashlar, formerly lodgings for a Church Officer, situated to the southwest of the forecourt. They have four steps leading to a central door with a semicircular fanlight, flanked by matching, round-headed windows with cills. An adjoining polygonal link connects to the building on the right.

The church has timber sash and case windows. A coped ashlar gablehead stack features original octagonal cans to the right, along with ashlar skews, and grey slates.

Ashlar gatepiers with flat pyramidal caps, a low coped wall, simple iron railings, and two pairs of iron gates define the boundary to High Street.
