It is divided from the mainland by the River Alde, and was formed by longshore drift along the coast. The material of the spit comes from places further north, such as Dunwich. Near the middle point of its length, at the foreland point or "Ness", once stood Orfordness Lighthouse,<ref>{{cite web | title=Orfordness Lighthouse | url=http://www.trinityhouse.co.uk/interactive/gallery/orfordness.html | publisher=Trinity House | access-date=11 October 2007 | archive-url=https://web.archive.org/web/20071031032453/http://www.trinityhouse.co.uk/interactive/gallery/orfordness.html | archive-date=31 October 2007 | url-status=dead | df=dmy-all }}</ref> demolished in summer 2020 owing to the encroaching sea.<ref name="auto">{{cite web|title=Orfordness Lighthouse: Historic Suffolk landmark reduced to rubble|url= https://www.bbc.com/news/uk-england-suffolk-53735247|date= 11 August 2020|publisher=BBC}}</ref> In the name of the lighthouse (and the radio transmitting station – see below), "Orfordness" is written as one word.

==History== thumb|left|Orford Ness is the peninsula left of and below the river (River Alde) in this 1588 map The peninsula was formerly administered by the Ministry of Defence, which conducted secret military tests during both world wars and the Cold War. The site was selected as the location for the Orfordness Beacon, one of the earliest experiments in long-range radio navigation. The Beacon was set up in 1929 and used in the pre-war era. In the 1930s Orford Ness was the site of the first purpose-built experiments on the defence system that would later be known as radar. Having proved the technology on Orford Ness, Robert Watson-Watt and his team moved to nearby Bawdsey Manor and developed the Chain Home radar system in time for its vital role in the Battle of Britain.<ref>{{cite web |url=http://www.visit-orford.co.uk/articles/the-birthplace-of-radar-orford-ness-greatest-secret |title=The Birthplace of Radar - Orford Ness' Greatest Secret |first=Paddy |last=Heazell |publisher=Visit Orford |access-date=21 April 2018}}</ref>
The Atomic Weapons Research Establishment had a base on the site, used for environmental testing, i.e. testing conducted to determine the functional performance of a component or system under conditions that simulate the real environment in which the component or system is expected to operate. Many of the buildings from this time remain clearly visible from the quay at Orford, including the distinctive "pagodas".<ref>{{cite web |url=https://historicengland.org.uk/listing/the-list/list-entry/1416933 |title=Orford Ness: the Atomic Weapons Research Establishment test buildings and associated structures |publisher=Historic England |access-date=21 April 2018}}</ref>
{{Orford Ness map}} In the late 1960s an experimental Anglo-American military over-the-horizon radar known as Cobra Mist was built on the peninsula. It closed in 1973, and in the late 1970s and early 1980s the site and building were re-used for the Orfordness transmitting station. This powerful medium-wave radio station – originally owned and run by the Foreign Office, then the BBC and, after privatisation in the 1990s, a series of private companies – was best known for transmitting the BBC World Service in English around the clock to continental Europe on 648 kHz from September 1982 until March 2011. The following year, the site became disused until Radio Caroline began broadcasting from it in December 2017.<ref>{{cite web |title=The Transmission Gallery - Orford Ness |url=https://tx.mb21.co.uk/gallery/gallerypage.php?txid=1654 |website=tx.mb21.co.uk |access-date=29 November 2025}}</ref>
Orford Ness is now owned by the National Trust and is open to the public under the name Orford Ness National Nature Reserve, though access is strictly controlled to protect the fragile habitats and due to a residual danger to the public from the site's former use by the military. Access is available only by the National Trust ferry from Orford Quay on designated open days.<ref>{{cite web|author=road |url=http://www.nationaltrust.org.uk/orfordness |title=Orford Ness National Nature Reserve |publisher=National Trust |access-date=2018-04-21}}</ref> Urban explorers have also visited the site.<ref>{{Cite web |url=https://www.28dayslater.co.uk/threads/orford-ness-awre-and-cobra-mist-suffolk-october-2018.115056/ |title=Exploration Report - Orford Ness AWRE and Cobra Mist - Suffolk - October 2018 |website=www.28dayslater.co.uk |access-date=29 November 2025}}</ref>
Rachel Woodward writes: <blockquote> It is a place of strange contrasts. For the National Trust, its "elemental nature" contrasts with the "inherent dangers" of this place, a "hostile and potentially dangerous site". Military structures – the Bomb Ballistics Building, the Black Beacon, the "pagodas" used for explosive design – have been converted into viewing spots. This is not a celebratory site, however; there is ambivalence and doubt here, with regard to what is being physically and ideologically conserved.<ref>{{cite book | title=Military Geographies | first=Rachel | last=Woodward |date=October 2004 | publisher=Blackwell Publishing | isbn=1-4051-2777-5}}</ref>{{efn|Note: Woodward states that the testing grounds closed in the early 1990s.}} </blockquote>
Owing to its military history, its stark appearance and the fact that it was closed to the public for many decades, several apocryphal stories have circulated about Orford Ness. The best-known is the suggestion that Nazi troops attempted to invade England and actually disembarked at the tip of the peninsula near Shingle Street, before being repelled with a wall of fire. Official sources denied that any such attempted invasion took place, an assertion confirmed by classified documents released in 1993. More recently, the flashes of the lighthouse were implicated in the Rendlesham Forest UFO sightings of late December 1980. In 2013, Trinity House announced that the lighthouse was to be decommissioned as an aid to navigation and marked on UKHO charts as disused.<ref>{{Cite web |url=http://www.trinityhouse.co.uk/mariner_info/notice_to_mariners/c/27032013.html |website=www.trinityhouse.co.uk |archive-url=https://web.archive.org/web/20130502014703/http://www.trinityhouse.co.uk/mariner_info/notice_to_mariners/c/27032013.html|title=Notice to mariners|archive-date=2 May 2013}}</ref> It was demolished in summer 2020.<ref name="auto"/>
In September 2023, the National Trust employed contractor Bam (working with Historic England and University College London's Bartlett School for Sustainable Construction) to survey the site - in particular, the AWRE Labs 4 and 5, or pagodas - using drones and a dog-like robot named Spot, manufactured by US firm Boston Dynamics. Concrete decay meant the buildings could not be safely surveyed by human surveyors. National Trust archaeologist Angus Wainwright said the team wanted "to see if it's possible to do a really detailed building survey with no human operator in the building."<ref name="TCI-11Sep2023">{{cite news |title=Robot dog surveys nuclear weapons site |url=https://www.theconstructionindex.co.uk/news/view/robot-dog-surveys-nuclear-weapons-site |access-date=11 September 2023 |work=The Construction Index |date=11 September 2023}}</ref>

The spit formed almost entirely of flint deposited by waves through the process of long-shore drift. The main influence on its formation has been storm waves throwing shingle over the top of the beach crest, where it is protected from ordinary wave action. Over time, this process leads to the formation of stable ridges of fine particles, and swails of coarser shingle.<ref name="evans" />
The size and shape of the spit have fluctuated over time (see map). Estimated growth rates range from 64m per year in 1962 to 1967, to 183m per year in 1804 to 1812.
