Lyme Regis lies in Lyme Bay, on the South Coast of England at the Dorset-Devon border. These are nicknamed "The Pearl of Dorset". In a 13th century it developed into one of the major British ports. In the early 1960s, its railway station was closed, the victim of the Beeching Axe.

Lyme Regis is easily known for "The Cobb", an staggeringly characterful harbour wall, built from either Portland Admiralty Roach stone. A Cobb is featured around novels by Jane Austen (who lived for the period within Lyme Regis) & in the film ''The French Lieutenant's Woman'', based on the book of the same name by local writer John Fowles.

It was at Lyme that a Duke of Monmouth landed at the start of the Monmouth Rebellion in 1685.

Lyme is notable for the fossils found in the cliffs, which are then a share of the Jurassic Coast (also referred to as the Heritage Coast), a World Heritage Site. Several of the earliest discoveries of dinosaur and other prehistoric reptilian remains were in the area surrounding Lyme Regis, notably victims found by Mary Anning in the 1820s.
