Clogher (from Irish Clochar, meaning 'stony place';[1] /ˈklɔː.ər/,[2] /ˈklɒ.hər/[3]) is a village and civil parish in the border area of south County Tyrone, Northern Ireland.

[6] Clogher is home to the provincial office in Northern Ireland for the congregation of the Sisters of Mercy[7] (Roman Catholic order of nuns).

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');[11] probably on the site of the medieval monastery or a nearby ringfort.

[13][14] 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 to the faith.

"[14] The stone is recorded as being "a curiosity in the porch of the Cathedral of Clogher" in the time of Annalist Cathal Maguire of Fermanagh in the late 15th century.

[17] St. Aedh Mac Cairthinn of Clogher (c. 430–505 AD) an early disciple and companion of Saint Patrick[18] founded a monastery at the site, which later the Synod of Rathbreasail recognised as an episcopal see.

In 1932, the sisters of saint louis were invited to Clogher by request of the Bishop to open a catholic primary school and convent.
