The Blue Lagoon

Nowadays the Blue Lagoon's whole purpose is leisure but there is history here. This was not always open to the sea, rather it was a slate quarry and the slate was transported by a narrow guage railway to Porthgain, which we will see in a while, the slate was not of the highest quality but just looking at the vast hole that has been quarried quite a lot must have been sold. When the quarry was working it was obviously not called the Blue Lagoon and it was after it closed that local fishermen blasted out the entrance to form a natural harbour for their boats. Even the fishing has now declined and the leisure industry has taken over, Abereiddi Quarry is now The Blue Lagoon and very popular with the coasteering fraternity.
