Drumragh RC Parish Hall, ACCORD and Parish Office, (Former Christian Brothers Primary School), 48 Brook Street, Omagh, Co Tyrone, BT78 5HD

A detached multi-bay two-storey stone former schoolhouse dated 1859, situated on an elevated site at the south end of Brook Street in Omagh. It forms part of a complex of parish-related buildings around the Sacred Heart Roman Catholic Church and the Loreto Convent, and is the earliest structure in this group, predating the neighbouring mid-nineteenth-century parochial house, the late-nineteenth-century church, and the Convent.

The building is rectangular on plan, facing north, with a three-bay three-storey addition to the west. The main block is constructed of square-and-snecked dressed basalt at ground floor and coursed squared rubble at first floor, with dressed sandstone quoins. The basement has straight-channelled sandstone quoins, V-jointed. Pitched artificial slate roof with red brick chimneystacks to the east gable and yellow brick chimneystacks to the gable ends of the west block. Ogee-profile cast-iron gutters are mounted on dressed sandstone corbels.

Windows throughout are square-headed timber 6/6 sashes with flush red brick surrounds, smooth-rendered cement reveals, and stone lintels. The principal north elevation is eight openings wide. The central entrance is a replacement raised-and-fielded two-panel door under a square-headed double-leaf surround in painted stone. The lintel carries a cornice with a lugged panel inscribed "CHRISTIAN SCHOOLS / MOUNT ST. COLUMBA / 1859". The first floor window above the entrance is surmounted by a Latin Cross gablet. At the ground floor right end is a round-headed double-leaf door with cement-rendered reveals and flush red brick surround.

The west addition (ground floor and second floor) has a central arched door opening with plate glass tympanum, surmounted by a moulded sandstone surround with keystone and marble Latin cross. The west block rear elevation has a door to the ground floor and a round-headed 10/6 sash window to the second floor. The west gable has a single second-floor window. The east gable of the former schoolhouse is two windows wide with round-headed timber 10/6 sashes.

The rear south elevation is eight openings wide. The first floor, third opening from the right, is a door accessed by an external modern metal balcony and stairs wrapping the southeast corner. At the ground floor right end is a door; four openings from the right end is a round-headed window, formerly a door with sandstone lintel and Gibbs-blocking.

The datestone confirms the building's construction date of 1859. The Christian Brothers School first appears in Valuation Revisions 1860–1864, valued at £16, with Rev. Manus O Kane as occupier and leased from James Greer. By 1933, the Christian Brothers Secondary School was recorded in the Revisions with Rev. Brother Burke as occupier, leased from Very Rev. John Mac Shane. The building is first shown on the third edition Ordnance Survey map of 1905–6.

Although changes have been made, including replacement doors and modern additions, the building's essential robust character and simple plan survive. It stands to the west of the parochial house (HB11/11/001C) and to the east of the Sacred Heart Roman Catholic Church (HB11/11/001A), with a modern parochial house to the southwest. The building is now in use as a parish office and pastoral centre.
