Kilve has the remains of a red-brick retort built in 1924 after the shale in the cliffs was found to be rich in oil. Along this coast, the cliffs are layered with compressed strata of oil-bearing shale and blue, yellow and brown Lias embedded with fossils. The Shaline Company was founded in 1924 to exploit these strata but was unable to raise sufficient capital. The company's retort house is thought to be the first structure erected here for the conversion of shale to oil and is all that remains of the anticipated Somerset oil boom.
