The civil parish of Clogher covers areas of County Fermanagh as well as County Tyrone. History Clogher is home to the provincial office in Northern Ireland for the congregation of the Sisters of Mercy (Roman Catholic order of nuns). From 1971-1991 The Mercy Order employed some of their nuns at St Macartan's Primary School following the leave of the order of saint louis as the school was actually founded by the Sisters of St Louis in the 1930s due to the high demand for primary Catholic education in the Clogher area. The Sisters of Mercy also had ownership of the St Macartan's nursing and dementia care home until recent years where they decided to hand the nursing home over to the NHS. The sisters of Saint Louis left Clogher in the 1970s and the Mercy Order continued their work. However, In the late 1980s the Sisters of Mercy were phased out of the school and retired from the job of teaching at St Macartan's School due to falling numbers of nuns and as a newer curriculum had been introduced in Northern Ireland it meant they needed more qualifications. They have since severed most ties with the St Macartan's Convent School but still live in the Convent of Mercy on the Ballagh Road, Clogher, next to the St Macartan's nursing home. The name Clochar refers to something made of stone ('cloch' is the Irish word for 'stone' and can be anglicised as 'cloch', 'clogh' or 'clough'); probably on the site of the medieval monastery or a nearby ringfort. Archaeological remains from before the 5th century have been found in the vicinity. Clogher is said to have been the location of a gold-covered pagan oracle stone named Cermand Cestach. The story goes that "Cloch-Ór (Golden Stone), may have been a ceremonial or oracle stone (see Cenn Cruaich and Omphalos) originally covered in gold sacred to the druids...given to Mac Cairthinn by an old pagan noble (Cairpre, the father of St Tigernach of Clones), who had harassed him in every possible way until the saint's patient love won the local ruler
