The coastal plain where the North Downs meet the Strait of Dover has been of strategic importance since ancient times. Portus Lemanis was a major Roman harbour, overlooked by a fort near where Lympne Castle now stands. The Normans built Folkestone Castle on a spur of Cheriton Hill. The church of St Martin dates back to Saxon times and the name Cheriton means "Church Farm". The British government purchased a large piece of land at Shorncliffe in 1794 and fortified it in preparation for the expected French invasion. Shorncliffe Redoubt is significant as the birthplace of modern infantry tactics. A Royal Commission was set up in 1859 during another invasion panic, which led to the construction of the Palmerston Forts and Shorncliffe Army Camp. The Army presence led to a dramatic growth of Cheriton in the second half of the 19th century. This led to the distinction being lost between Cheriton and Folkestone, whose expansion was funnelled westward by the escarpment of the Downs. Construction of the Channel Tunnel began in 1988 and it opened in 1994. The passenger terminal is wedged between the Downs and the M20 motorway just west of Castle Hill, and freight trains are marshalled at Dollands Moor Freight Yard further west.
Cheriton sits on a level shelf halfway up the escarpment of Folkestone Downs, between Cheriton Hill on the landward side and Sandgate Hill going down to the sea. The Folkestone Downs are the southern end of the North Downs, a low range of chalk hills running from London to the White Cliffs of Dover. The Seabrook Stream flows through the west of the district, cutting a scenic valley between Dibgate Camp and St Martin's Plain.
Demography
The population in 1851 was 1,658, which by 1861 had grown to 7,434 – of whom 4,204 were military in Shorncliffe Camp. the Royal Gurkha Rifles occupy Shorncliffe Camp so Nepali people make up a large part of the population.
Economy
The local economy is dominated by the barracks and Channel Tunnel terminal.
The Folkestone White Horse overlooks Cheriton from the Downs north of the Channel Tunnel terminal. The earthworks of Folkestone Castle are just to the east.
Transport
on the South Eastern Main Line served the village between 1908 and 1947. It was just east of the bridge on Risborough Lane. The Elham Valley Way is a long-distance path that runs between Cheriton and Sandgate on its way up to Canterbury. Stagecoach in East Kent operates local bus services to Canterbury every hour or to the town centre of Folkestone up to every 8 minutes.
Education
was one of the main secondary schools in Folkestone and Hythe.
Religious sites
There were four churches in the Benefice of Cheriton, which comes under the Deanery of Elham. The church of St Martin is very ancient, the base of the thirteenth-century tower may have been a Saxon porch. The decorative arcading in the chancel is made of Bethersden marble and is very finely carved. The churchyard contains the grave of shipping reformer Samuel Plimsoll, and, among many military burials, 24 CWGC-registered war graves, with all three armed forces represented, 15 from World War I and nine from World War II. The church gives its name to the military training area of St Martin's Plain and now serves Shorncliffe Camp. All Souls church was built in response to the population growth of the late 19th century. The old parish was split along the railway embankment, with the parish of Cheriton Street being formed north of the line. A farmer's widow, Mrs Thompson, died in 1887 leaving a plot of land on the High Street and a bequest of £10,000 for the construction of a church. All Souls was designed by Ewan Christian and consecrated on 3 January 1895. St. Nicholas is a small rural church in the outlying village of Newington. The barracks had the largest garrison church in Britain but in 2001 it was sold for conversion into a theatre. The three active churches are served by Revd Hilary Jones, who lives in St Martin's Rectory, Horn Street. Cheriton Baptist Church is just along the High Street from All Souls. St Joseph's Catholic Church is between the two, on Ashley Avenue.
was a preacher and fabulist who in 1233 inherited land in Cheriton, Rochester and elsewhere from his father, James William of Cheriton. Samuel Plimsoll, the man who gave his name to the Plimsoll line used to indicate the limit of a ship's load, is buried in St Martin's churchyard, as is judge and politician Sir James Knight-Bruce.
