Site of Special Scientific Interest in the context of "South Pennines"

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.

Hampstead Heath is an ancient heath in London, spanning 320 hectares (790 acres). This grassy public space sits astride a sandy ridge, one of the highest points in London, running from Hampstead to Highgate, which rests on a band of London Clay. The heath is rambling and hilly, embracing ponds, recent and ancient woodlands, a lido, playgrounds, and a training track, and it adjoins the former stately home of Kenwood House and its estate. The south-east part of the heath is Parliament Hill, from which the view over London is protected by law.

Running along its eastern perimeter is a chain of ponds – including three open-air public swimming pools – which were originally reservoirs for drinking water from the River Fleet. The heath is a Site of Metropolitan Importance for Nature Conservation, and part of Kenwood is a Site of Special Scientific Interest. Lakeside concerts are held there in summer. The heath is managed by the City of London Corporation, and lies mostly within the London Borough of Camden, with the adjoining Hampstead Heath Extension and Golders Hill Park in the London Borough of Barnet.

Kents Cavern is a cave system in Torquay, Devon, England. It is notable both for its archaeological and geological features (as a karst feature in the Devonian limestone). The cave system is open to the public and has been a geological Site of Special Scientific Interest since 1952 and a Scheduled Ancient Monument since 1957.

Goonhilly Downs is a Site of Special Scientific Interest (SSSI) that forms a raised plateau in the central western area of the Lizard peninsula in southern Cornwall, England. It is one of 229 English national nature reserves designated by Natural England with an area of almost 1,270 hectares.

The West Pennine Moors is an area of the Pennines covering approximately 90 square miles (230 km) of moorland and reservoirs in Lancashire and Greater Manchester, England. It is a Site of Special Scientific Interest.

The West Pennine Moors are separated from the main Pennine range by the Irwell Valley to the east. The moorland includes Withnell, Anglezarke and Rivington Moors in the extreme west, Darwen and Turton Moors, Oswaldtwistle Moors and Holcombe Moors. These moors are lower in height than the main spine of the South Pennines. At 1,496 feet (456 m), the highest point is at Winter Hill. The area is of historical importance with archaeological evidence of human activity from Neolithic times. The area is close to urban areas, the dramatic backdrop to Bolton, Blackburn and Bury and neighbouring towns affording panoramic views across the Lancashire Plain and the Greater Manchester conurbation. The moorland is surrounded by the towns of Bolton, Chorley, Darwen, Horwich, Ramsbottom, Haslingden and Oswaldtwistle. Notable structures include Rivington Pike Tower, Winter Hill transmitting station, Peel Monument near Holcombe and the Jubilee Tower on Darwen Moor.

Cissbury Ring is an 84.2-hectare (208-acre) biological Site of Special Scientific Interest north of Worthing in West Sussex. It is owned by the National Trust and is designated a Scheduled monument for its Neolithic flint mine and Iron Age hillfort.

Cissbury Ring is the largest hill fort in Sussex, the second largest in England and one of the largest in Europe overall, covering some 60 acres (24 hectares). The earthworks that form the fortifications were built around the beginning of the Middle Iron-Age possibly around 250 BC but abandoned in the period 50 BC - 50 AD.

Milton Keynes (/kiːnz/ KEENZ) is a city in Buckinghamshire, England, about 50 miles (80 km) north-west of London. At the 2021 Census, the population of its urban area was 264,349. The River Great Ouse forms the northern boundary of the urban area; a tributary, the River Ouzel, meanders through its linear parks and balancing lakes. Approximately 25% of the urban area is parkland or woodland and includes two Sites of Special Scientific Interest (SSSIs). The city is made up of many different districts.

In the 1960s, the government decided that a further generation of new towns in the south east of England was needed to relieve housing congestion in London. Milton Keynes was to be the biggest yet, with a population of 250,000 and area of 22,000 acres (9,000 ha). At designation, its area incorporated the existing towns of Bletchley, Fenny Stratford, Wolverton and Stony Stratford, along with another fifteen villages and farmland in between. These settlements had an extensive historical record since the Norman Conquest; detailed archaeological investigations before development revealed evidence of human occupation from the Neolithic period, including the Milton Keynes Hoard of Bronze Age gold jewellery. The government established Milton Keynes Development Corporation (MKDC) to design and deliver this new city. The Corporation decided on a softer, more human-scaled landscape than in the earlier English new towns but with an emphatically modernist architecture. Recognising how traditional towns and cities had become choked in traffic, they established a grid of distributor roads about 1 km (0.6 mi) between edges, leaving the spaces between to develop more organically. An extensive network of shared paths for leisure cyclists and pedestrians criss-crosses through and between them. Rejecting the residential tower block concept that had become unpopular, they set a height limit of three storeys outside Central Milton Keynes.

Chichester Harbour is a large natural harbour in West Sussex and Hampshire. It is situated to the south-west of the city of Chichester and to the north of the Solent. The harbour and surrounding land has been designated as an Area of Outstanding Natural Beauty (AONB) and a biological and geological Site of Special Scientific Interest (SSSI). The area is also part of the Solent Maritime Special Area of Conservation, Chichester and Langstone Harbours Ramsar site, Special Protection Area and Nature Conservation Review site, Grade I. Part of it is a Geological Conservation Review site and two areas are Local Nature Reserves.

Five institutional landowners that own land or foreshore within Chichester Harbour SSSI include the Crown Estate, the Church Commissioners, the Ministry of Defence (around Thorney island), the National Trust (East Head) and the Royal Society for the Protection of Birds (Pilsey Island).
