This beautiful church, built in 1826 was designed by the famous Dublin architect John Semple. Semple was the leading architect in Dublin during the 1820’s and 1830’s. Many of his designs are in the ‘late English Gothic style’ and some of his other notable churches are Blackchurch, Donnybrook, St. Maelruans in Tallaght, Monkstown and Whitechurch. He was also involved in the design of the inside of ‘The Round Room’ on Dawson Street. The earliest mention of the name Kilternan occurs in the Papal Taxation Rolls of 1306 and the first record of the parish as being the property of St Mary’s Abbey of Dublin is in a charter dated 1406. Kilternan is one of the view villages in Ireland that lacks a traditional village centre and is also the location of Ireland’s only artificial ski slope.
