The Aberthaw limekilns were built in 1888 to burn blue lias limestone pebbles collected from the foreshore. The original works comprised two pots each with a diameter of 18ft and a capacity of 300 tons. The daily combined output was 40 tons of burned lime. After 1900 a pair of large oval pot draw kilns was added at the rear. The kilns were abandoned in 1926.
