The original structure was built of oak piles and rubble before being reinforced with stone over successive centuries.
It is a man-made structure designed to create a calm harbour basin in a section of coast otherwise exposed to heavy seas.
The stones forming the pier are known as 'Cow's' stones, likely due to a corruption of the name Cobb.
The wall has been destroyed and rebuilt by storms multiple times throughout its 700-year history.
It acts as a primary landing point for day-trippers and fishing excursions along the West Dorset coast.
The Cobb is a historic stone harbour wall located in Lyme Regis, Dorset, serving as the town's primary breakwater and port. Originally constructed in the 13th century, its current structure features a curved design that protects the harbour from south-westerly gales. The pier is built from large limestone blocks and serves as both a functional maritime facility and a public walkway extending into the English Channel. It gained international literary fame as the setting for pivotal scenes in Jane Austen's 'Persuasion' and John Fowles's 'The French Lieutenant's Woman'. The harbour entrance remains active, housing local fishing vessels and commercial charter boats. Visitors can walk along the top of the wall to observe the coastline and the Jurassic Coast fossil beds. The structure is maintained as a Grade I listed monument.

Wear footwear with good grip, as the uneven stone surfaces become slippery when wet or covered in sea spray.
Check local tide tables; high tide provides the most dramatic wave action against the wall, while low tide reveals the harbour floor.
Hold onto handrails during windy conditions, as the exposed path offers no shelter from sea gusts.
Do not attempt to walk on the wall if sea conditions are rough or overtopping waves are present.
Avoid walking near the edge during high winds or rough sea states for safety.
