Red Rock Martello Tower is located in Sutton on the North side of Dublin. It is beautifully situated on a rocky shoreline looking toward Dún Laoghaire on the South side of Dublin. You cannot see this particular tower from the nearby road and entrance. You must walk through a gated area to a path that leads to this beauty. The owners have converted this structure into a vacation rental. I am looking forward to staying here once I have all the Martello Towers of Ireland documented.
