Why would you think twice about retiring to Lyme Regis in 50 years time?
This is the town of Lyme Regis on the Jurassic Coast
The Jurassic Coast is a natural World Heritage Site and is internationally important for its rocks, fossils and coastal landforms. It stretches for 95 miles, from Exmouth in East Devon to Swanage in Dorset. You can see 185 million years of geological time in 95 miles of coastline! Erosion is a very important process for maintaining the natural beauty of the coastline and ensuring that fossils and fresh geological exposures help scientists study the coastline. Coastal defences are the biggest threat to the World Heritage Site since they affect the natural process of erosion Lyme Regis is here Key Facts

A dynamic coast Winter storms attack the base of the cliffs and case erosion Erosion is an important process that maintains the natural beauty of the coast and reveals scientifically important fossils over time.
Why are there landslides in Lyme Regis? The town is built on a layer of strong limestone which is very solid. On top of that layer there are slippery muds, clays and sands which slide over the limestone layer to form the landslides. The sea erodes the cliffs at the bottom of the landslide, causing it to become unstable and slip even further. Houses, buildings and roads become damaged as the land slips towards the sea. Black Ven is the largest and most active coastal landslide in Europe!
