Royal Naval Air Station Culham (RNAS Culham, also known as HMS Hornbill) was a former Royal Navy, Fleet Air Arm station near Culham, Oxfordshire. It opened in 1944 as an All Weather Airfield for the Royal Navy. The airbase was used by Receipt and Despatch Unit No.2, No.1 Ferry Flight, 739 Photographic Trials and Development Unit and home to 1832 R.N.V.R. (Air) Squadron.The airbase is situated around 5 miles (8.0 km) south of the city of Oxford, with the village of Culham lying 1 mile (1.6 km) to west. The notable landmarks include the city of Oxford where through it runs The Isis, which then forms a loop around the airfield to the north, west and south as it flows south east. The market town of Abingdon-on-Thames is about 2 miles (3.2 km) to the north west. Didcot junction, where a line running north/south, intersects the Great Western Main Line, is situated 3 miles (4.8 km) south, with Culham railway station, on the north/south Oxford-Didcot line, at the south west corner of the airfield.The ground layout was typical of many bomber stations, with three runways. However it had many hangars, mostly sited around the field's perimeter. Initially HMS Hornbill was used to train reservists based in the Thames Valley area using several different types of aircraft including: Supermarine Seafire, a navalised Supermarine Spitfire fighter aircraft, Hawker Sea Fury, a single-seat fighter aircraft and North American Harvards, an American single-engine advanced trainer aircraft. In May 1947 the Photographic Trials and Development Unit was based at HMS Hornbill, and in 1951 1840 Naval Air Squadron operated from the airfield for a short time. Ab initio flight training of cadets from Britannia Royal Naval College, Dartmouth, flying primary gliders, was also undertaken here in the early 1950s.

The Small Tight Aspect Ratio Tokamak, or START was a nuclear fusion experiment that used magnetic confinement to hold plasma. START was the first full-sized machine to use the spherical tokamak design, which aimed to greatly reduce the aspect ratio of the traditional tokamak design. The experiment began at the Culham Science Centre in the United Kingdom in 1990 and was retired in 1998. It was built as a low cost design, largely using parts already available to the START team. The START experiment revolutionized the tokamak by changing the previous toroidal shape into a tighter, almost spherical, doughnut shape. The new shape increased efficiency by reducing the cost over the conventional design, while the field required to maintain a stable plasma was a factor of 10 less.

The Culham Centre for Fusion Energy (CCFE) is the UK's national laboratory for fusion research. It is located at the Culham Science Centre, near Culham, Oxfordshire, and is the site of the Joint European Torus (JET), Mega Ampere Spherical Tokamak (MAST) and the now closed Small Tight Aspect Ratio Tokamak (START). Formerly known as UKAEA Culham, the laboratory was renamed in October 2009 as part of organisational changes at its parent body, the United Kingdom Atomic Energy Authority (UKAEA).Since 2016, the director has been Professor Ian Chapman, and the centre has been engaged in work towards the final detailed design of ITER as well as preparatory work in support of DEMO. In 2014 it was announced the centre would house the new RACE (Remote Applications in Challenging Environments).

Mega Ampere Spherical Tokamak (MAST) was a nuclear fusion experiment, testing a spherical tokamak nuclear fusion reactor, and commissioned by EURATOM/UKAEA. The original MAST experiment took place at the Culham Centre for Fusion Energy, Oxfordshire, England from December 1999 to September 2013. A successor experiment called MAST Upgrade began operation in 2020.

Reaction Engines Limited is a British aerospace manufacturer based in Oxfordshire, England.

Culham railway station serves the village of Culham in Oxfordshire, England. It is on the Cherwell Valley Line between Didcot Parkway and Banbury, 56 miles 17 chains (90.5 km) from London Paddington. It is served by local train services provided by Great Western Railway. The station is just off the A415 road, between the villages of Culham and Clifton Hampden. It is close to Culham Science Centre, an 80-hectare (200-acre) scientific research site housing two nuclear fusion experiments: JET and MAST. The Science Centre was built on the site of RNAS Culham (HMS Hornbill), a World War II airfield.

Lock Wood Island is an island in the River Thames in England just downstream of Nuneham House on the reach above Abingdon Lock. The island sits on a sharp bend in the river. It is densely covered with tall trees and has a narrow channel behind it. In the nineteenth century there was a thatched cottage on the island linked to the bank by a rustic bridge which was a popular place for picknickers. Alice Liddell used to visit the island with Lewis Carroll, who penned Through the Looking-Glass shortly after one of these visits. There is evidence of weirs and flash locks here, at one time owned by Lord Harcourt, which may account for the name of the island.

The Carfax Conduit was a water conduit that supplied the city of Oxford with water from 1610 until 1869. The conduit ran in an underground lead pipe from a spring on the hillside above the village of North Hinksey, beneath Seacourt Stream and the River Thames, to a building at Carfax in the centre of Oxford. The system was built by Otho Nicholson, a London lawyer, to supply the citizens of Oxford with clean water. It replaced a system built by Osney Abbey between 1205 and 1221 that had fallen into disrepair.The conduit building at Carfax was an elaborate structure, some 40 feet (12 m) tall, with eight niches containing statues of historic and mythical figures. By 1787 it had become an obstacle to traffic and it was removed in 1797 and replaced by a smaller cistern. The original structure was given to the Earl Harcourt, who had it re-erected in the grounds of his home, Nuneham House, where it remains to this day. Two plaques are attached to opposite sides of the building, giving a short history in English and Latin. The re-erected conduit is a Grade I listed building and scheduled monument.A building, now called the Conduit House, was built at Harcourt Hill over the spring. It remains in situ and is in the care of English Heritage. The Conduit House site is designated as a Grade II* listed building and a scheduled monument.The entire system fell into disuse in the 19th century. In 1869, when it was carrying very little water, the conduit was sold to Oxford Corporation.

Clifton Hampden Bridge is a road bridge crossing the River Thames in Clifton Hampden, Oxfordshire, England, situated on the reach below Clifton Lock. Originally it joined Oxfordshire on the north bank with Berkshire on the south but in 1974 the area on the south bank was transferred from Berkshire to Oxfordshire. It is a Grade II* listed building.Clifton Hampden Bridge was designed by Sir George Gilbert Scott and opened in 1867. The bridge replaced a ferry service which had operated on the site since at least the early 14th century. From its opening a toll was payable but this ceased in 1946 when the County Councils of Berkshire and Oxfordshire joined to buy the bridge from its private owners.

Clifton Hampden is a village and civil parish on the north bank of the River Thames, just over 3 miles (5 km) east of Abingdon in Oxfordshire. Since 1932 the civil parish has included the village of Burcot, 1 mile (1.6 km) east of Clifton Hampden. The 2011 Census recorded the parish population as 662.

Clifton Hampden Manor is a country house in the village of Clifton Hampden, Oxfordshire, England, overlooking the River Thames. It has been a Grade II listed building since 1987.It was built by Sir Gilbert Scott about 1843–46 as a parsonage for Henry Hucks Gibbs, who in 1896 became Hucks Gibbs, 1st Baron Aldenham. It was soon extended, probably by Charles Buckeridge, for the Revd. J.L. Gibbs.In 2000, a descendant, the antiques dealer and collector and 60s figure Christopher Gibbs reluctantly sold the house, and Christie's auctioned off the contents over two days.The house is now owned by the singer-songwriter Kate Bush.

Nuneham Viaduct, also known as Nuneham Railway Bridge and the Black Bridge is near the town of Abingdon-on-Thames in Oxfordshire, England. It is a two-span, bowstring truss bridge that carries the Didcot to Oxford section of the Cherwell Valley Line across the River Thames between Abingdon Lock and Sandford Lock. Its name is derived from the neighbouring Nuneham House. The total length is 99 yards (91 m); the southern and northern ends are respectively 57 miles 24 chains (92.22 km) and 57 miles 29 chains (92.32 km) from Paddington (via Didcot station).As well as passenger trains, the line over the bridge carries freight from the Port of Southampton to distribution centres in the Midlands and North of England. By 2023, up to forty freight trains per day were using the route, which is part of the core UK intermodal freight network, and was to have been part of the proposed Electric Spine. From March 2022, the bridge suffered a progressive failure with sinking of the southern end of the southern span. This led to its temporary closure to all rail traffic on 3 April 2023 and a major remedial project being undertaken; the line was reopened to traffic on 9 June 2023.
