1820 – Tynan Abbey, Co. Armagh
Designed by John Nash who had a cluster of work in the area including Caledon House in Co. Tyrone, and some lodges at Castle Leslie in Co. Monaghan, both very close by. Later adapted by William Barre and W.H. Lynn.
Destroyed in a terrorist attack in 1980 when Republicans attacked the house, murdered the owner and his son, and set fire to the building. The ruins were later demolished due to safety concerns.
