I don't know of a monument but I happened to run across this (below) when searching on Wikipedia for Lisnarable:Eskra (from the Irish: Eiscreach meaning "ridges of gravel or sand") is a small village located in the south-west of County Tyrone, Northern Ireland, on the Omagh to Clogher road, about 10 miles from Omagh and about 4 miles from Clogher. It was originally part of Clogher and also contains the hamlet of Newtownsaville.
The Roman Catholic parish church is named St. Patrick's. The Protestant Church of Ireland is named St. Mark's. Drinkers in the village are served by the Bridge Tavern (also known as O'Hagan's) and Marlow's Pub in Newtownsaville (formerly known as McSorley's).
