[9] St. Tighernach had received the benediction of St. Maccartin, granted the bishopric of Clogher and performed many miracles across Ireland, Britain and France.

[11] The cult of Tighernach, which grew from his legend, was propagated a branch of the Uí Cremthainn who migrated to the Clones area in the 8th century.

The Clones abbey of SS Peter and Paul promoted Tighernach outside of the diocese that his cult extended across the British Isles.

[14] Having been confiscated by the English Crown during the Plantations of Ireland, the entire church estate was subsequently leased to Elizabethan explorer Sir Henry Duke in 1587.

[15] During the Irish Rebellion of 1641, Clones was the site of conflicts between native Gaelic gentry and newly settled planters from Great Britain.

The Depositions state that Irish rebels, led by MacMahons of Oriel (Monaghan) hoping to restore their ancestral lands, looted and burned properties now occupied by planters; targeting rich farmers and their tenants.

[15] On 11 February 1922, during the partition of Ireland, there was an armed confrontation in Clones between the Irish Republican Army (IRA) and the Ulster Special Constabulary (USC).

A unit of armed Special Constables stopped off at Clones railway station while travelling by train from Belfast to Enniskillen (both in Northern Ireland).

[17] During The Troubles, on 28 December 1972, a car bomb exploded on Fermanagh Street in Clones, seriously injuring two men.

This happened on the same day as the Belturbet bombing in County Cavan which killed two teenagers and injured several other people.

Gardaí said they believed the UVF linked loyalist paramilitary group the Red Hand Commandos were behind the bombing.

[10] The remains that can be seen today include an Augustinian abbey, round tower, 18th century, pictographic tombstones and the stone sarcophagus of St. Tighernach.

The shaft is older dating from 825 to 875 AD, it is decorated with interlacing beads that run up the sides and form a collar at the top.

[21][14] The Norman Motte and Bailey are large earthen structures located behind the St Tighearnach's Church of Ireland.

A sketch dating to 1586-7 shows evidence of churches being present on the site from before the land was leased to Sir Henry Duke by the English crown.

[15] The 17th century structure was replaced in 1822–25 by a building designed by John Bowden, Board of First Fruits diocesan architect, or his successor William Farrell.

It features a steep set of fourteen sandstone steps, a three staged tower with ashlar masonry and a crenellated parapet topped with a spire with pointed-arch windows with chamfered surrounds and hood mouldings.

The occupants of the castle sallied multiple times and, armed with muskets, harassed the Jacobite forces.

This drove the Jacobites into negotiation with the occupants offering the security of their lives and property in exchange for the surrendering of the castle.

Clones Community Forum applied for a Heritage Council grant to contract an archaeological team to investigate the site in 2016.

The Partition of Ireland in 1922 made Clones a border post on the railway, which combined with road competition to cause the Great Northern to decline.

This stadium is regularly used for inter-county matches during the Ulster provincial championship in Gaelic football, and traditionally hosts the final.

[38] Clones Film Festival has been held during the October bank holiday for the past twenty years.

It includes the screening of international and Irish feature films of a wide variety of genres and age ratings.

It is features a number of short film competitions including the 'Francie' award named after Patrick McCabe's The Butcher Boy.

[42] The Flat Lake Festival was an annual arts, music and cultural event hosted by Kevin Allen from 2007 to 2011 at Hilton Park, a country house and demesne located between Clones and Scotshouse.
