the landscape feature on Antarctic King George Island

North Foreland is a chalk headland on the Kent coast of southeast England, specifically in Broadstairs. With the rest of Broadstairs and part of Ramsgate it is the eastern side of Kent's largest peninsula, the Isle of Thanet. It presents a bold cliff to the sea, 15 miles north of South Foreland, and commands views over the southern North Sea. LB&SCR H2 class 4 4 2 no. 422 (later no. B422, 2422, and 32422) was named North Foreland after this landmark.

There was probably some sort of a beacon at an earlier period but the first distinct intimation concerning a lighthouse on the North Foreland is in the year 1636 when Charles I by letters patent granted to Sir John Meldrum licence to continue and renew the lighthouses erected on the North and South Forelands. It seems that the lighthouse erected by Sir John consisted merely of a house built with timber lath and plaster on the top of which a light was kept in a large glass lantern for the purpose of directing ships in their course. This house was burnt down by accident in the year 1683 after which for some years use was made of a sort of beacon on which a light was hoisted. But near the end of the same century a strong octagonal structure of flint was erected on the top of which was an iron grate quite open to the air in which a good fire of coals was kept blazing at night.

About the year 1732 the top of this lighthouse was covered with a sort of lantern with large sash windows, and the fire was kept bright by bellows with which the attendants blew throughout the night. This contrivance is said to have been for the purpose of saving coals but it would seem more probable that it was in order to preserve the fire from being extinguished by rain. However the plan did not work well and great injury resulted to navigation as many vessels were lost on the sands from not seeing the light, and so little was it visible at sea that mariners asserted that they had often in hazy weather seen the Foreland before they could discover the light. They added that before the lantern was placed there and when the fire was kept in the open air the wind kept the fire in a constant blaze which was seen in the air far above the lighthouse. Complaints of this sort were so loud and frequent that the governors of Greenwich Hospital sent Sir John Thomson to examine and make arrangements on the subject. He ordered the lantern to be taken away and things to be restored to nearly their former state, with the light to continue burning all the night until daylight. placed behind a row of solid glass convex lenses which were incorporated within the glazing around the lantern room. In it, under the supervision of engineer Henry Norris, a new multi wick oil burner was installed together with a large (first order) fixed catadioptric optic manufactured by Sautter & Co. of Paris (replacing the previous catoptric apparatus of 18 Argand lamps & reflectors); it was first lit on 26 March 1860. Three months later a red sector was added to the light, which shone northwards 'to enable vessels at night to keep to the eastward of Margate Sand'. (These works coincided with the successful experiments carried out in 1857–60 at the South Foreland lighthouse by Professor Frederick Hale Holmes with an alternating current electric arc light). At the same time the tower itself was modernised: two keepers' cottages were built alongside and the interior of the tower (which had previously contained rooms on several storeys) was completely gutted. Most of the exterior windows were blocked at this time, and the exterior of the tower was rendered and painted white. This work was completed in 1866, leaving the lighthouse looking much the same as it does today. The light was further improved in 1894 when a Trinity House pattern eight wick heavy mineral oil burner was installed in place of the old oil lamp. The light source was a tungsten filament lamp (with an identical lamp being provided as a standby along with an acetylene lamp for emergencies, all three mounted on an automatic lamp changer). Also in 1930 a radio beacon was established at North Foreland. By the late 1980s North Foreland Lighthouse was operating as an area control station, with an augmented crew of keepers monitoring (in addition to North Foreland itself) eleven other major aids to navigation (including light vessels in the Dover Strait and the lighthouses at Dungeness and Beachy Head). Dermot Cronin and Tony Homewood were the last Principal Lighthouse Keepers that manned North Foreland lighthouse. The actual last manned lighthouse, owned by the Lancaster Port Commission was Walney Light, automated in 2003.

The lighthouse remains operational and is monitored and controlled by Trinity House from its Planning Centre at Harwich. The 1860 optic is still in use with a modern light source displaying a group flashing characteristic. A painting of the lighthouse by Elwin Hawthorne is in the Russell Cotes Art Gallery & Museum in Bournemouth. Currently, the cottages around the lighthouse can be rented as holiday accommodation. In electoral wards as most often drawn, postally as to post town and in the Church of England it remains part of Broadstairs.

A coastal radio station was established adjacent to the light house in 1901. Its call sign was 'GNF'. The transmitting function was later moved about a mile inland, although the medium wave receiving aerial remained operational until closure in 1991.
