Rainey-Goddard Monument Knockbreda Parish Church of Ireland, Church Road, Belfast, County Down, BT8 7AN

The Rainey-Goddard mausoleum is a free-standing stone monument erected around 1790 commemorating William Rainey and his descendants. It stands to the northeast of Knockbreda Parish Church in an extensive graveyard north of Upper Knockbreda Road, Belfast.

The mausoleum is square on plan with four equal elevations. Each face features a central rectangular inscribed memorial plaque flanked by Doric pilasters. Continuous plinth bases support engaged Doric columns at each corner. A stepped entablature above the pilasters carries swags to the frieze. The composition is crowned by a pavilion stone roof with stone pinnacles at each corner and a central draped urn. The structure employs Adamesque detailing characteristic of Georgian funerary architecture.

William Rainey (c.1740–1803) came from a family that had settled in Ulster as planters in the early seventeenth century and prospered through interests in linen and provisions, establishing themselves at Greenville House on the edge of Belfast by the mid-eighteenth century. Moderate in politics, Rainey was eventually compelled to join the Yeoman Cavalry Corps as its first lieutenant and was later appointed Deputy Governor of Belfast. Buried at Knockbreda with him are his mother, father, sister, brother-in-law, first wife and ten of his children, many of whom died young. Notably, his seven-year-old son Boyd died in a shooting accident at school when two older boys, intending to hunt a cuckoo, stole a gun.

The Rainey-Goddard mausoleum is one of four large mausolea erected in the last two decades of the eighteenth century at Knockbreda, all square on plan with elegant Adamesque arrangements of Classical columns, pilasters and entablatures. These monuments commemorate some of Belfast's most prominent citizens. The High Street graveyard in Belfast, where Protestants had traditionally been buried, was closed to new burials in 1798 due to persistent flooding, after which Knockbreda became a popular burial place for the city's most notable inhabitants. Roger Mulholland, a notable local architect, may have been responsible for the tombs, though documentary evidence is lacking. Belfast's position as a port may have exposed local architects to architectural influences from overseas, particularly India, where funerary monuments of this type had become common by the mid-eighteenth century. The mausolea have been described as the "oddest and finest of all buildings in the genre in Ulster". One of the four was demolished in the later twentieth century, while the remaining three fell into poor condition before their restoration by the Follies Trust. A full restoration of the Rainey-Goddard mausoleum was completed in 2009 by the Follies Trust under the supervision of Chris McCollum. The mausoleum has group value with the nearby listed Waddell-Cunningham-Douglas and Greg mausolea and Knockbreda Parish Church.
