The history of Abereiddy Quarry and the Blue Lagoon in Wales
Pembrokeshire was a leading area for the slate industry in Wales. It’s estimated that there were over 100 quarries in the area at its peak.
The ‘Blue Lagoon’ is a ruin of the St Brides Slate Quarry in Abereiddy that was established in the 19th century. Similar to the quarry of Porthgain, it was in use from the 1840s to the 1890s.
Back then, this quarry was linked to Porthgain by a tramway that was worked by horses. They would transport the slate that was extracted here by cart! The slate would then be shipped out from Porthgain.
At some point during its use, parts of the quarry were blasted away. It was a request from the local fisherman as they wanted a narrow channel to access the lagoon to shelter their boats.
The quarry was purposefully flooded and much of the stone on the cliffside fell into the sea. It’s the sediment from the slate stone that turned the water blue and created the name ‘Blue Lagoon’.
By 1910, Abereiddy Quarry was out of use, and the area was completely abandoned. The quarry buildings and workmen’s cottages later fell into disrepair.
Nowadays, the Blue Lagoon is protected by the National Trust and this phenomenon is visited by thousands each year!
