Lemgare Mass Rock in The Parish of Clontibret, County Monaghan is situated adjacent to the neighboring townlands of Lisdrumgormley and Crossbane which is in Co. Armagh. A Mass rock was a rock used as an altar in mid-17th century Ireland as a location for Roman Catholic Mass. From a Statute of the Synod of Clones, held by Blessed Oliver Plunkett in 23 August 1670, we can see how a local Mass-site could have been selected in those times. It was decreed at the time that a place be appointed that was convenient to the parish priest and the parishioners. Church law at the time explains why some penal-day Mass sites were to be found centrally situated in a parish, others on the borders of two or more parishes to convenience the worshipers.
1731 Report
The "Report on the State of Popery of 1731" identifies "Atlars ut supra" in the Parish of Clontibret. "Ut supra" is Latin for "as stated above" and the entry reads ‘one Altar made of earth & stones uncovered’. The entry also relates to multiple altars, these possibly being those located at Lemgare and Tassan. This means that knowledge of the Mass Rocks in the townlands of both Lemgare and Tassan potentially dates back to at least 1731.
1957 survey
Lemgare Mass was along with that of Tassan Mass Rock, and Mass Gardens and Dunfelimy Mass Hut were recorded in a survey carried out by Rev P O'Gallachair in 1957 on behalf of the Diocese of Clogher, and this survey was aided by Very Rev Larry Marron Adm. of Clontibret Parish at the time. Rev. O'Gallachair mentions the "Mass Rock" in Dunfelimy being "on the site of old church of Annyalla". In making this reference he is picking up a point by over thirty years earlier by Fr James E McKenna in his ‘Parishes of Clogher’, Vol. I. The opinion is that there may be a mix up between a Mass Rock in Dunfelimy and perhaps a structure which predated the old chapel at Annyalla which was built in the late 1790s. At the time of the survey Lemgare Rock was reported as being on the lands of John Brennan, now deceased. The Brennan homestead can be clearly seen in the photo shown looking north west.

Strategic location
Lemgare Mass Rock would have been a good location for the people from the surrounding parishes to attend mass. In those times there were no physical borders in Ireland and people went to and from county to county and parish to parish with relative ease. Indeed, up to the 1930s a lot of young people from Derrynoose Parish would have indeed come to school in Lemgare. The location of Lemgare Mass Rock would have been strategically important due to its;
Elevation it would have near on impossible for any approaching Army to surprise the parishioners whilst they prayed
Proximity to the adjoining Parish of Derrynoose- Derrynoose parish suffered greatly at the hands of the soldiers of Oliver Cromwell with the destruction of churches and property. It is widely accepted that Cromwell's men fired a cannon at the old Church in Derrynoose. However it is not clear if Cromwell was actually there as it is claimed that he did not go north at all. The cannon seems to have been fired from Macklin's hill which would be well over half a mile away.
