Seymours Bridge School, Ahoghill Road, Randalstown, Co. Antrim, BT41 3DJ

Seymours Bridge School is a plain, detached four-bay single-storey roadside school built around 1825, now vacant and derelict. It stands on the east side of Ahoghill Road, facing west, with its simple rectangular plan emphasised by an isolated and exposed setting.

The building is constructed of lime-rendered random rubble walls with a pitched slate roof featuring squared ridge tiles, overhanging at the gable ends with carved exposed rafter ends and a brick corbel-course. Smooth rendered red brick chimneys sit at both gable ends, each topped with a corbel-course. Round cast iron downpipes and cast iron half-round gutters with brackets provide the rainwater goods. The principal elevation contains an entrance opening (now boarded) in the left bay, with windows to the remaining bays. The windows are round-headed with masonry cills, though all are now boarded with timber panels. The left gable is blank, whilst the rear elevation is three-bay with a window in each bay, also boarded. The right gable is blank. Brick flue repairs are visible where lime render has detached.

The site fronts the roadside with vehicular access to the south. It is bounded to the north and east by hedges, with a river running from north to south to the rear of the building and a bridged lane providing access to fields behind.

The school appears on the first edition Ordnance Survey map of 1832–34 with the same plan as today. The 1838 Ordnance Survey Memoirs describe it extensively as 'a good house, thatched, 22 and a half by 16 feet' with the teacher earning £5 for the last quarter, paid by the children. The memoir notes it as 'one of the oldest in the district but was rebuilt in 1837' and lists the textbooks in use as Manson's Primer and Spelling Book, Murray's Reader and English Grammar, and Gough's Arithmetic.

A former pupil who attended until the school's closure in 1936 recalls a capacity of 40 pupils, with infants separated from older children by a screen. Miss McNeill taught the younger pupils and Mr Sams was the principal. The building contained an outside toilet and an open fireplace in the schoolroom. Following closure, the schoolhouse was used for Wednesday and Sunday prayer meetings until the late twentieth century, since which time it has remained vacant. The building's interior has survived with its single classroom plan layout remaining largely intact, though proposals for conversion would remove historic fabric and compromise its character.
