Kilmovee takes its name from Cill Mobhi, the Church of Mobhi, after a sixth-century cleric known as Mobhi the Teacher. His name is a pet form of Berchan, and he is believed to have died in 544 during a pestilence that swept Ireland and scattered his disciples. One of those disciples was Columba, who left for Ulster and would later sail for Iona. The teacher is gone, the original church long vanished, but the village still carries his memory in its name. The three wells beside the ogham stone are folk memory anchored to landscape - the kind of story that survives because the place itself refuses to let it die.

Before the Normans arrived, this corner of Mayo belonged to the Kingdom of Sliabh Lugha, ruled by the O'Gadhra Dynasty. Sliabh Lugha was a subdivision of the larger Gailenga kingdom, the name surviving today in the modern barony of Gallen. Then came the Nangles - the de Angelo family - riding southwest from De Lacy territory in Carrick-on-Shannon. They forced the O'Gadhras from their stronghold at Airtech Mor and raised their own castle on the site in 1225. It became known as Castlemore, and the surrounding region took the name Castlemore-MacCostello. The kingdom dissolved into a barony, the chiefs into tenants, the old order into a new one written in stone and Latin charter.

Three Royal Irish Constabulary barracks once stood in the parish - at Kilkelly, Rathnagussaun, and Sraheens. The Sraheens building is still there, derelict but standing, a low grey shell that has outlived the empire it was built to police. In June 1921, during the War of Independence, the Kilkelly Company of the East Mayo IRA opened sniper fire on the barracks under the command of Mick Moffett. A single Black and Tan was wounded. That was enough. The barracks was abandoned, and the constabulary's grip on this corner of Mayo quietly slipped. The walls of Sraheens still mark the spot where one small skirmish helped end an occupation.

In 1975, a teacher named Seosamh Mac Gabhann founded a senior ceili band in the village and named it Ceoltoiri Mobhi, after the long-dead saint. The band found audiences beyond the parish, and two of their tunes entered the trad repertoire as The Kilmovee Jigs. Two years later, in 1977, the village opened one of the first rural swimming pools in Ireland - a small civic miracle for a place this size. Mac Gabhann died in 2008. Since 2011, the Seosamh Mac Gabhann Summer School has gathered each year in Kilmovee to honour the Irish-language playwright and music teacher who spent most of his life here. The Cois Tine Heritage Centre, opened in March 2004, anchors the village's cultural calendar.

Since April 2010, Kilmovee has hosted an annual charity ten-kilometre run that draws competitors from across the country. Its reputation rests on a single boast: locals call it the flattest ten in Ireland. In a country of hills and weather, that is a serious claim and a serious draw. The route loops through the rural parish where weavers once worked and where, in 1837, Samuel Lewis described a quiet country settlement on the road to Ballaghaderreen. The runners pass the same fields, the same hedges, the same wide Mayo sky. The course beneath their feet hasn't changed much. Only the speed has.
