This is Martello Tower No. 7 located on Killiney Hill in South County Dublin. It is one of about fifty Martellos built by the British. Many were built along our eastern coastline from Drogheda all the way down to Bray. Dublin Bay had a high concentration of them as twenty-six towers were built in sight of each other providing the ability to communicate and warn of any incoming attacks by the French Navy. ‘Martello No.7’ is unique for its unusual location of half a kilometer up on a hill away from the sea but was useful as a lookout post. It has been beautifully restored over a 10 year period and includes a proofed 18-pounder cannon. There is also a coach house, an artillery store, a tool shed, a gunner’s cottage (with a resident gunner), and a gunpowder store. The tower is now privately owned but is sometimes open to the public. When the restoration was completed on the 12th of July 2008 it was inaugurated by the firing of its cannon.
