North Downs in the context of "Calcareous grassland"

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. A section of coastline encompassing the cliffs was purchased by the National Trust in 2016.

The cliffs are part of the Dover to Kingsdown Cliffs Site of Special Scientific Interest and Special Area of Conservation. 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. A celebrated UK landmark, the cliffs have featured on commemorative postage stamps issued by the Royal Mail, including in their British coastline series in 2002 and UK A-Z series in 2012.

A dry valley may develop on many kinds of permeable rock, such as limestone, chalk, sand stone and sandy terrains that do not regularly sustain surface water flow. Such valleys do not hold surface water because it sinks into the permeable bedrock.

There are many examples of chalk dry valleys along the North and South Downs in Southern England. Notably the National Trust-owned Devil's Dyke near Brighton covers some 200 acres (0.81 km) of downland scarp, and includes the deepest dry valley in the world – created when melting water eroded the chalk downland to the permafrost layer after the last ice age. The three-quarter mile long curved dry valley is around 700 feet (210 m) in height and attracts tourists with its views of Sussex, Hampshire and Kent.

Epsom is a town in the borough of Epsom and Ewell in Surrey, England, about 14 miles (22 kilometres) south of central London. The town is first recorded as Ebesham in the 10th century and its name probably derives from that of a Saxon landowner. The earliest evidence of human activity is from the mid-Bronze Age, but the modern settlement probably grew up in the area surrounding St Martin's Church in the 6th or 7th centuries and the street pattern is thought to have become established in the Middle Ages. Today the High Street is dominated by the clock tower, which was erected in 1847–8.

Like other nearby settlements, Epsom is located on the spring line where the permeable chalk of the North Downs meets the impermeable London Clay. Several tributaries of the Hogsmill River rise in the town and in the 17th and early 18th centuries, the spring on Epsom Common was believed to have healing qualities. The mineral waters were found to be rich in Epsom salts, which were later identified as magnesium sulphate. Charles II was among those who regularly took the waters and several prominent writers, including John Aubrey, Samuel Pepys and Celia Fiennes recorded their visits. The popularity of the spa declined rapidly in the 1720s as a result of competition from other towns, including Bath and Tunbridge Wells.

Farnham is a market town and civil parish in Surrey, England, around 36 miles (58 km) southwest of London. It is in the Borough of Waverley, close to the county border with Hampshire. The town is on the north branch of the River Wey, a tributary of the Thames, and is at the western end of the North Downs. The civil parish, which includes the villages of Badshot Lea, Hale and Wrecclesham, covers 14.1 sq mi (37 km) and had a population of 39,488 in 2011.

Among the prehistoric objects from the area is a woolly mammoth tusk, excavated in Badshot Lea at the start of the 21st century. The earliest evidence of human activity is from the Neolithic and, during the Roman period, tile making took place close to the town centre. The name "Farnham" is of Saxon origin and is generally agreed to mean "meadow where ferns grow". From at least 803, the settlement was under the control of the Bishops of Winchester and the castle was built as a residence for Bishop Henry de Blois in 1138. Henry VIII is thought to have spent part of his childhood under the care of Bishop Richard Foxe and is known to have lived at Farnham Castle when he was 16.

The River Medway is a river in South East England. It rises in the High Weald, West Sussex and flows through Tonbridge, Maidstone and the Medway conurbation in Kent, before emptying into the Thames Estuary near Sheerness, a total distance of 70 miles (113 km). About 13 miles (21 km) of the river lies in East Sussex, with the remainder being in Kent.

The Medway has a catchment area of 930 square miles (2,409 km), the second largest in southern England after the Thames. The map opposite shows only the major tributaries: a more detailed map shows the extensive network of smaller streams feeding into the main river. Those tributaries rise from points along the North Downs, the Weald and Ashdown Forest.

Folkestone (/ˈfəʊkstən/ FOHK-stən) is a coastal town on the English Channel, in Kent, south-east England. The town lies on the southern edge of the North Downs at a valley between two cliffs. It was an important harbour, shipping port, and fashionable coastal resort for most of the 19th and mid-20th centuries.

This location has had a settlement since the Mesolithic era. A nunnery was founded by Eanswith, granddaughter of Æthelberht of Kent in the 7th century, who is still commemorated as part of the town's culture. During the 13th century, it developed into a seaport, and the harbour developed during the early 19th century to defend against a French invasion. Folkestone expanded further west after the arrival of the railway in 1843 as an elegant coastal resort, thanks to the investment of the Earl of Radnor under the urban plan of Decimus Burton.

The M25 or London Orbital Motorway is a major ring road encircling most of Greater London. The 117-mile-long (188 km) motorway is one of the most important roads in the UK and one of the busiest. Margaret Thatcher opened the final section in 1986, making the M25 the longest ring road in Europe upon opening. The Dartford Crossing completes the orbital route but is not classed as motorway; it is classed as a trunk road and designated as the A282. In some cases, including notable legal contexts such as the Communications Act 2003, the M25 is used as a de facto alternative boundary for Greater London.

In the 1944 Greater London Plan, Patrick Abercrombie proposed an orbital motorway around London. This evolved into the London Ringways project in the early 1960s, and by 1966, planning had started on two projects, Ringway 3 to the north and Ringway 4 to the south. By the time the first sections opened in 1975, it was decided the ringways would be combined into a single orbital motorway. The M25 was one of the first motorway projects to consider environmental concerns and almost 40 public inquiries took place. The road was built as planned despite some protests that included the section over the North Downs and around Epping Forest which required an extension of the Bell Common Tunnel.

Downland, chalkland, chalk downs, or just downs are areas of open chalk hills, largely turfed with grass, such as the Chiltern Hills and North Downs.
