The White Cliffs are famous as a national landmark on the south coast of the UK. 

The vertical cliffs are up to hundreds of meters high, with its chalk face looking into the endless sea. It's almost like a dream scene. 

Over millions of years, the chalk layers, made of a fine and pure white limestone, are formed gradually from the skeletal remains of marine creatures. 

From Dover, there are a chain of white cliffs from west to east, such as Beachy Head, Seven Sisters, Seaford and Jurassic Coast. 

A shot of the white cliffs appeared in the film "Dunkirk," marking the success of the Dunkirk evacuation. The UK coastline with white cliffs is a natural navigation landmark for British pilots during World War II. When they saw the cliffs in the air, they cheered for returning to the motherland. 

The White Cliffs of Dover is the closest point to continental Europe, facing the English Channel. The cliffs provide home for rare species of wildlife, including butterflies, birds and wildflowers. 

To encourage biodiversity and protect the species, the tradition of grazing is kept, and Exmoor pony is an ideal breed to keep the ecologic system here balanced by consuming bushes and grasses.
