White Cliffs
A celebrated UK landmark, their striking appearance has met visitors since ancient times.
The White Cliffs of Dover are the region of English coastline facing the Strait of Dover and France. The cliff face, which reaches a height of 350 feet (110 m), owes its striking appearance to its composition of chalk accented by streaks of black flint, deposited during the Late Cretaceous. The cliffs, on both sides of the town of Dover in Kent, stretch for eight miles (13 km). The White Cliffs of Dover form part of the North Downs. The cliffs are part of the Dover to Kingsdown Cliffs Site of Special Scientific Interest and Special Area of Conservation. The top of the cliffs hosts a chalk grassland ecosystem with an abundance of bird, flower, and butterfly species.

Lore & Background
The cliffs mark the point where Great Britain is closest to continental Europe; on a clear day the cliffs are visible from France, approximately 20 miles (32 km) away. Julius Caesar remarked upon their appearance when he invaded Britain in 55 BC. The cliffs served as a natural defensive barrier, reinforced by the building of Dover Castle in the 11th century. The cliffs gained symbolic importance during World War II, as a symbol of Britain's resolute defence and as a welcome sight for the evacuees from Dunkirk. It is thought that the name Albion, an ancient or poetic term referring to Great Britain, was derived from the Latin albus (meaning 'white') as an allusion to the white cliffs.
Reader's Guide
The White Cliffs are at one end of the Kent Downs designated Area of Outstanding Natural Beauty. In 1999 a sustainable National Trust visitor centre was built in the area. The Gateway building, designed by van Heyningen and Haward Architects, houses a restaurant, an information centre on the work of the National Trust, and details of local archaeology, history and landscape. The chalk grassland environment above the cliffs is excellent for many species of wild flowers, butterflies and birds, and has been designated a Special Area of Conservation and a Site of Special Scientific Interest.
Rangers and volunteers work to clear invasive plants that threaten the native flora. A grazing programme involving Exmoor ponies has been established to help to clear faster-growing invasive plants, allowing smaller, less robust native plants to survive. The ponies are managed by the National Trust, Natural England, and County Wildlife Trusts to maintain vegetation on nature reserves.

- The chalk was deposited during the Late Cretaceous, between 100 million and 66 million years ago, at a rate of about half a millimetre a year.
- In 2001, a large chunk of the cliff edge, as large as a football pitch, fell into the Channel.
- After a 120-year absence, ravens returned to the cliffs in 2009.
