Banbridge Court House, Victoria Street, Banbridge, Co Down, BT32 3DH

Banbridge Court House is a Victorian Italianate stucco two-storey former courthouse built in 1872–73 to designs by Henry Smyth, county surveyor for the Northern Division of County Down. It is located on the south side of Victoria Street in Banbridge town centre.

The building comprises a rectangular main block with projecting single-storey wings to east and west, each with a projecting entrance porch. A modern single-storey extension to the south, in similar style, has been added. The roof is hipped natural slate with rendered chimneystacks topped by moulded caps. Cast-iron downpipes and hoppers are fitted throughout, and the façade features lead-capped corbel courses with bracketed and Lombardic frieze.

The walling is painted stucco over a moulded plinth with decorative moulded string courses at impost level at each floor and continuous sills. Pierced circles punctuate the parapet over the main block and wings. The principal elevation faces east and displays two blind arcaded openings to the first floor centre. Windows to the main block are round-headed with geometric glazing bars and pierced window aprons. Those to the wings are 1/1 timber-framed sliding sashes with horns, framed by pilasters with carved heads and corbels under sills. All openings have moulded archivolts.

The ground floor of the east elevation is partially abutted by the wider eastern wing. The central projecting porch has a 1/1 window and four-panelled bolection-moulded timber doors to left and right cheeks, surmounted by a plain fanlight. The porch is flanked by paired windows to left and right bays. An exposed section to the northwest contains a small abutment with an oculus.

The south elevation has three windows to the first floor and is abutted at ground floor by the modern extension. The west elevation has two openings to the first floor and is abutted at ground floor by the projecting wing. The central projecting entrance porch on this elevation contains a 1/1 window and a steel fire door to the left cheek; the right cheek has an inverted four-panelled bolection-moulded timber door with brass doorknob. An exposed section to the northeast has a small abutment with an oculus. The north elevation is three windows wide to the first floor; the ground floor displays three decorative circular mouldings to the centre between the moulded string course and continuous sill.

The building was constructed as a replacement for the petty sessions court previously held on the upper floor of the market house. The tender of John Thompson for construction was accepted in March 1872, with the building opening in October 1873 at a cost of £2,465, met by a Grand Jury presentment; furnishings cost a further £90. The site was donated by the local landowner, the Marquess of Downshire. At the opening Half-Yearly Sessions, the generosity of the Grand Jury and the comforts provided were commended, with favourable comparison made to other courthouses in Ireland. A contemporary street directory described the style as Gothic-Italian and judged it the "handsomest edifice of its kind in County Down". Later architectural appraisal found it "an opulent and individual Italianate extravaganza in stucco".

The building functioned with the main body housing the courtroom and the two wings accommodating the witnesses' room, bar room, magistrates' room and jury room with lavatories accessed from the four rooms. A wash house was located in the yard, and a court keeper's house and garden to the rear. Prisoner cells were located in the basement. In the 1880s, quarter sessions for civil cases were heard here, though more serious criminal cases were sent to Newry for trial.

Henry Smyth was county surveyor for the Northern Division of County Down and designer of Downpatrick Lunatic Asylum, as well as co-designer with Charles Lanyon of the Ormeau Bridge in Belfast.

In recent years the building has been extended to the rear with protective walls erected around the perimeter. Recent interior remodelling has compromised its character through the loss of historic fabric. The building remains in use as a courthouse.

The building is set back from Victoria Road and enclosed to the north by a tall painted render wall with stone coping topped by security fencing. It is bounded to the east by a rubble stone wall with square rock-faced stone pier, topped by security fencing and a large steel entrance gate. Bollards and a security gate mark the east entrance. A modern library is situated to the south, and a large modern cinema complex has been constructed on the north side of Victoria Street. The security fencing and modern setting compromise the original setting of this significant civic building.
