Aberthaw Lime Works

[3] It was built to utilise the huge number of Limestone Pebbles that had previously been taken inland or been moved by boat.

A tramway ramp (again demolished) allowed carts containing pebbles between 3 & 4 inches (100 mm) in diameter to be conveyed to the top of the works and then into the kilns.

It was the subject of an important series of experiments in 1756-7 undertaken by John Smeaton to test the setting qualities of lime in sea water preparatory to designing and building the Eddystone lighthouse.

[8] The fame it got from its use at the Eddystone and other lighthouses naturally led to increased demand which could not be fully met until this major new works was built.

The arrival of the railway enabled it to be properly serviced with the necessary coal for firing, as well as the ability to transport the lime away.
