The sand was imported and the whole beach/promenade created linking LC to PDLA.
many many moons ago, they were 2 seperate resorts and walking from PDLA was not like it is today on the beautiful promenade.
You walked on waste land and literally had to climb over rocks that jutted out into the sea to walk under the now tunnel, that brings you out near the harbour.
That tunnel was nothing more than an oversize sewer pipe with no lights and you were hardly able to stand upright in it.
When they created the beach the locals were scavenging the huge shells that the diggers were excavating up.....to sell later
Memories
PS. I actually threw some bits of a video together for another members question, and this will show you the beach....the videoclip is a bit "ropey" by my standard today.
