History
Until the 1650s, Gortnacleigh formed part of the modern townland of Cloncose and its history is the same up till then. From medieval times up to the early 1600s, the land belonged to the McKiernan Clan. A 1629 Inquisition spells the name as Garticloyche. The 1652 Commonwealth Survey spells it as Gartnecleighh. An Inquisition held at Cavan on 10 June 1629 stated that the poll of Cloncose, belonging to Sir Alexander Hamilton, contained four sub-divisions named Gortnekillefohin, Knockanvisfuit, Gartinnecassaghe and Moneshein. It also described the boundary of the townland as- bounding upon Drumnoass on the north, meared thorow a greate boge to Ballina and Garticloyche, and from thence meered by a running brooke or streame to Knocknehorna. The 1652 Commonwealth Survey states the landowner was Sir Francis Hamilton. The 1790 Cavan Carvaghs list spells the townland name as Gortnecliff. The 1825 Tithe Applotment Books list eight tithepayers in the townland. The Gortnacleigh Valuation Office books are available for April 1838. Griffith's Valuation of 1857 lists five landholders in the townland. The landlord of Gortnacleigh in the 19th century was Hugh Wallace.
An earthen fort. The Archaeological Survey of County Cavan states- Raised circular area enclosed by a substantial earthen bank and a fosse. An earlier report recorded slight traces of an external bank at NW, ESE and SE. Break in bank with accompanying causeway at NE probably represents original entrance. The 1937 Dúchas folklore collection states- The Gortnacleigh Treasure. There is a treasure supposed to be hidden in Gortnacleigh Fort on the land of James Baxter under a great big stone. There were attempts made to get it, and it is said some of it was found by Patrick Baxter, Gortnacleigh. The treasure consisted of gold. It is said the treasure seemed to be gold that was rolled up in a bar. There is supposed to be a light guarding it at night. Other stories say that a fairy silver shoe was found beside it by John Donoho, Killeshandra.
