Harristown (Irish: Baile Anraí)[1] is a townland in County Kildare on the River Liffey 2.5 miles (4.0 km) downstream from Kilcullen,[2] just north of Brannockstown[3] in the civil parish of Carnalway in the barony of Naas South.
[5] In the 17th century Harristown House was built near the castle by the Lord Chancellor of Ireland, Sir Maurice Eustace.
In 1684 (regnal year 33),[6] Sir Maurice Eustace obtained a royal charter from Charles II incorporating Harristown as a borough.
[2][3][9] Authorised by an Act of the Parliament of Ireland, La Touche enclosed the grounds of the house, building the "New Bridge" over the Liffey to carry the redirected Naas–Dunlavin road[9] (now the R412).
[11] From 1886 to 1947 the Great Southern and Western Railway had a branch line from Naas to Tullow, which had a station at Harristown.
