Here's an image of the old Lower Lighthouse on Portland, now the bird observatory, which was taken by late Dorset Evening Echo photographer Harry Green.

One of three lighthouses on Portland, and formerly a private residence, in 1961 the Lower Lighthouse on the Bill Road became the island's Bird Observatory.

The higher lighthouse also became a private residence and among its various owners was birth control pioneer Doctor Marie Stopes, who made it her home for some time.

Thanks to Carole Dorran for digitising the Harry Green collection.
