Old National School St Marys Hall

St. Mary's Hall and No. 48, known as the Old National School, is a former National School and School House built in 1848, with an extension added in 1897 to commemorate Queen Victoria's Diamond Jubilee. The building is constructed of ragstone with brick quoins and features a clay plain tile roof. It is a single-storey structure with two rooms and a southwest porch. No. 48, which is attached to the northeast end of the school, has one storey and an attic.

The school has a front room with a southeast gable that includes a stone bellcote (the bell has been removed) supported by corbels. The roof slopes low over a four-light window on the right and the porch on the left. The porch features a moulded brick arch and has a tablet above it inscribed with "National School AD MDCCCXLVIII. Site given by W. Cook Esq. Wm Gould Vicar." Inside the porch, there is a brick floor and a boarded roof.

On the southeast side elevation, there is another porch with a moulded brick arch, along with one three-light window and two four-light windows, which are partly leaded. The northwest gable has a partly leaded three-light window and a single light window above it. The ragstone on the northeast elevation is concealed by later lean-to and flat-roofed additions.

The interior features a three-bay front school room with what is likely the original brick canopied fireplace that has a segmental head and chamfered joists. There is a contemporary cupboard on moulded corbels to the right. The school room has stopped and chamfered arch-braced trusses, similar to those in the rear seven-bay school room, which also has wainscot boarding on the walls, boarded doors (some with pointed heads), and a diagonally placed brick fireplace with a segmental head and chamfered jambs. A wooden board records the 1897 extension.

No. 48 has front and rear gables with segmental brick heads above the windows, one above and below in the front and one above at the rear. The rear elevation features a pointed brick arch on the left side. The northeast side elevation has two two-light windows with brick segmental heads, both above and below, with the upper windows set in attic gables. The interior retains 19th-century doors, cupboard doors, and a pilastered fireplace surround on the first floor, along with chamfered newels on the stair, all set within a 19th-century plan.
