This area falls within the Blue Anchor to Lilstock Site of Special Scientific Interest (SSSI) and is considered to be of international geological importance. 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.
