The Stewart Mausoleum, Carmavy Graveyard, Carmavy Road, Nutts Corner, Crumlin, Co Antrim

The Stewart Mausoleum is a late Georgian stone vaulted mausoleum in classical style, built in 1815 and retaining its original features. It stands in a prominent position within the walled graveyard at Carmavy, a rural historic site.

The mausoleum is a single-storey gabled rectangular structure constructed of galletted basalt rubble with slightly battered walls. The entrance faces west in a pedimented gable. The west gable contains a rectangular opening recessed between two broad rectangular projecting nib walls, accessed down two steps. The opening is spanned by a flat arch of rough basalt voussoirs and fitted with a plain iron barred gate, now permanently wedged open. Deep sandstone slabs rest over the nib walls, surmounted by an open triangular pedimented and bracketed classical aedicule containing a white marble plaque. The plaque is inscribed "Erected by Thomas L. Stewart to the memory of his beloved son Thomas Ludford Stewart who departed this life 5th January 1815". The pediment and shoulders of the gable are surmounted by three sandstone urns. The side walls are blank. The roof is of Bangor blue slates in diminishing courses with a tiled ridge, supported on a plain projecting eaves course in each side wall. Some splitting to the eaves course is visible on the north side. The rear gable contains a slightly recessed rectangular sandstone panel perforated by a cross with extended foot, with a triangular pediment above containing a small square sandstone panel perforated by a quatrefoil. A sandstone platband runs at eaves course level, with sandstone coping to the pediment.

The mausoleum was erected by Thomas L. Stewart in 1815 to commemorate his son Thomas Ludford Stewart junior, who died on 5 January 1815. It also contains memorials to Thomas Ludford Stewart senior (died 1845), Alexander Stewart of Ballyedmond, Rostrevor (died 1845), his wife Sophia (died 1848), Amelia, wife of Thomas Ludford Stewart (died 1849), and Robert Stewart (died 1854). The Ordnance Survey memoirs of the 1830s noted that "The respectable family of Shaw … and the family of Thomas Ludford Stewart of Belfast, Esquire, have handsome vaults here." The mausoleum is recorded as plot number 142 in the graveyard register.

The building stands on an east-to-west axis with two other mausolea to its east. It is approached by and faces directly onto a concrete path leading from the graveyard entrance, with grass surrounding the sides and rear. Directly opposite, across the path, is a small open enclosure with galletting to the exterior of its low plinth walls.
