Rockabill Lighthouse

 Skerries Sea Tours do trips to Rockabill. I'll have to do one some time. It appears the photos are a little better than the last time I posted but that's down to a better camera.

 Rockabill is in fact two islands off the coast of Skerries. The large one is called The Rock, the smaller one Bill (seen in the photo above) The lighthouse is built on the Rock. Some people call them The Cow and The Calf, examples of which nomenclature exist all around the shores of Ireland.

Built in 1860, the lighthouse sits on an island famous for its roseate terns. As a result, you're not allowed to land on the island in summer, only winter.
