On the right, Smeaton's Tower is the third and most notable Eddystone Lighthouse. In use from 1759 to 1877, it was largely dismantled and rebuilt on Plymouth Hoe in Plymouth, Devon, where it now stands as a memorial to its designer, John Smeaton, a celebrated civil engineer.
The sender wondered if there is a lighthouse on the left. There is not, but the First and Second World War Naval Memorial, unveiled in 1924.
This one is a second-hand postcard of the England's most South Westerly lighthouse: Longships.
This postcard was sent by the first time in 1965, when the stamp costed 3 old pence (1/80th of a pound). Modern postage is 117 new pence, or about 280 old pence.
Both postcards sent by John (the UK).
