Mount Mills Former Corn Mill Glen Road Drummiller Newry Co.Down BT34 1QS

Mount Mills is a former corn mill complex located on the west side of Glen Road, approximately 3.5 miles north-west of Newry, immediately north of the Newry Bypass at the Sheepbridge exit. The site comprises three surviving buildings: Building A (former corn kiln), Building B (former corn mill), and Building C (former grain store). A former Drover's Cottage also stands on the north side of the site. The complex is accessed via a laneway running from the Glen Road entrance on the north-east towards the south-west. Mount Mill Bridge lies immediately east of the mill complex on Glen Road, and a motte (scheduled monument) is located to the south-west.

The Former Corn Kiln (Building A) is a two-storey rectangular-plan structure of random-coursed rock-faced granite walling with a pitched artificial tiled roof running north-east to south-west. The north-west elevation displays tall rock-faced granite walling with a door opening at the extreme right, and two steel pattress plates are visible on the façade, though vegetation obscured parts of the elevation at survey. The south-west elevation is a gable end with a door opening at ground floor level featuring redbrick jambs and a window opening at attic level with remnants of a metal window frame; large quoin stones reinforce each corner. The south-east elevation, visible from the south side of the river, shows openings but is heavily obscured by vegetation and inaccessible at ground level. The gable wall leans towards the south-east towards the river.

The Former Corn Mill (Building B) is a large stone building running north-east to south-west, with the southern section re-roofed with corrugated metal sheeting and the northern section now derelict and roofless. Twentieth-century cement-rendered and concrete block farm structures are attached to the north-west side. The building drops down the hillside towards the river on the south-east side. The mill was aligned with a former mill race (now filled in) diverted from the Newry River. The south-west elevation is a gable heavily obscured by vegetation, with stonework visible at ground floor level and a door opening with brick voussoirs at the right side. The south-east elevation shows rubblestone walling brought to courses on the left section, much obscured by vegetation; the right section is largely derelict with large trees and vegetation growing through a large opening, with remnants of stonework remaining. The former water wheel is not extant.

The Former Grain Store (Building C) is a three-storey building facing south-east towards the river, built into the bank at the rear. It is constructed of random-coursed rock-faced granite walling with red brick dressings and a pitched natural slate roof. The south-east elevation presents an asymmetrical façade with a door opening at ground floor level, located off-centre towards the left side. Single window openings appear on each floor with red brick surrounds, aligned vertically, though no windows survive; some granite cills remain. The south-west elevation is built into the bank towards the rear and appears to be a blind façade largely obscured by vegetation. The north-east elevation is a three-storey blind façade built into the bank to the rear with a raised redbrick verge.

The complex is surrounded by open countryside on all sides and is situated in proximity to historic structures including Mount Mill Bridge and a motte.
