Hi, Bert. It's good to hear from someone else who remembers poetry from school. Thanks for your vote for the fiends.

Thanks for the link, Guest. The story of the Bell Rock lighthouse has much in common with the story of the Eddystone Light, which I have also read. Life was so hard and so sad then!

I suspect that 'Aberbrothock' in the poem is actually Arbroath. The ruined abbey is built of the same red sandstone as the Inchcape Rock.

It's easy to find a picture of the abbey online.
