This is what my lens was able to capture from 2 miles distance, significantly cropped. The blockhouse is to the left of the lighthouse.
Would have liked to have visited Scattery. It's got some interesting history to it, including the burial places of two saints and it's also the island where Brian Baru killed Ivar, the last Viking king of Norse Limerick.
