The builders were two brothers from Limerick, William and James Burgess. The chief materials used were granite from the Mourne Mountains in Co. Down and limestone from the local quarry in Milverton. The tower was built 83 feet high and the total cost of all the buildings, and apparatus, was £13,248 .The building was completed and the light was first operated on 1st. July 1860.
Skerries Seatours now do tours to Rockabill, as well as to Lambay Island, and so I availed of the opportunity to get up close with this lighthouse. The whole trip took about 80 minutes on a very fast rib and was very enjoyable. I was initially disappointed that we weren't allowed to land on the island (it is a bird sanctuary, home to the largest colony of roseate terns anywhere in the world) but the pictures from just offshore wouldn't have been improved by getting any nearer.
