Manor of the Archbishop, chartered before 1240
Edge of the Pale
After the Anglo-Norman conquest the lands of Rathcoole passed to the Metropolitan See and became one of the smaller manors of the Archbishop of Dublin, run by a portreeve like its neighbour Saggart. Archbishop Luke granted the burgesses of "Radcull" common of pasture and turbary on the mountain of Slievethoul before 1240. The village sat on the very edge of the Pale, the zone of English control, and for centuries it was raided by the O'Tooles and Byrnes coming down out of the Wicklow hills. Rathcoole, Saggart and Newcastle were held as fortified outposts precisely because everyone knew how exposed they were.
First stage south
The coach road
Before the railway and the motorway, the road from Dublin to Naas and the south of Ireland ran through Rathcoole, and it was the first significant stage out of the city - a place to change horses, eat something, and shelter for the night. That role gave the village several fortified houses and a main street built for traffic that no longer comes. The coaches are gone and the M7 carries the cars a field away, but the layout they left behind is still legible if you turn off the dual carriageway.
United Irishman, hanged 1803
Felix Rourke and the 1798 to 1803 rebellions
Felix Rourke was born near Rathcoole in 1765, the son of a small farmer who kept the turnpike gate on the Naas road. He joined the United Irishmen, caught the eye of Lord Edward FitzGerald, and was made colonel of the Kildare insurgents in 1798. He survived that rising, did time in Naas gaol, and was drawn back in when Robert Emmet returned to Dublin - Emmet's first meeting with the rebels in autumn 1802 was held at Rourke's house outside Rathcoole. After Emmet's failed rising of 1803 Rourke was arrested and hanged. A local history, Kerron Ó Luain's "Rathcoole and the United Irish Rebellions, 1798 to 1803", tells the full story.
Medieval ruin
St Mary's Church
The ruins of the medieval parish church of St Mary stand in the old village - a reminder, with the manor records, that there was a working settlement here in the thirteenth century and not just a coaching stop. It is a ruin, not a visitor attraction, but it anchors the old core and is worth a look if you are already walking the village.
