Chesil Beach //, sometimes called Chesil Bank, in Dorset, southern England is one of three major shingle structures in Britain. Its toponym is derived from the Old English ceosel or cisel, meaning "gravel" or "shingle".
The beach is often identified as a tombolo, although research into the geomorphology of the area has revealed that it is in fact a barrier beach which has "rolled" landwards, joining the mainland with the Isle of Portland, giving the appearance of a tombolo. The shingle beach is 29 kilometres (18 mi) long, 200 metres (660 ft) wide and 15 metres (50 ft) high. The beach and the Fleet are part of the Jurassic Coast, a UNESCO World Heritage Site, and the location for a 2007 novel, On Chesil Beach by Ian McEwan.
At the eastern end of the beach at the village of Chiswell, against the cliffs of the Isle of Portland, the beach curves round sharply to form Chesil Cove. This part of the beach protects the low-lying village from flooding. The beach has been the scene of many shipwrecks, and as such was named by Thomas Hardy as "Dead Man's Bay". Westwards the shingle forms a straight line along the coast, enclosing the Fleet, a shallow tidal lagoon.
Varying with the Bank's unbroken increase in height, to 14.7 metres (48 ft), above mean high water, the size of the flint and chert shingle varies from pea-sized at the north-west end (by West Bay) to orange-sized at the south-east end (by Portland). It is said that smugglers who landed on the beach in the middle of the night could judge "exactly where they were" by the size of the shingle.
There are three owners of the beach; the Crown Estates own the beach from Portland to its boundary stone at Littlesea. The bed of the lagoon and Chesil Beach adjacent to the Fleet, as well as the majority of the land of Upper Fleet to West Bexington, is owned by the Ilchester Estates, who are based north of Dorchester, but also have a local office in Abbotsbury. Finally from West Bexington to West Bay it is owned by the National Trust. The whole of Chesil Beach south from the Portland Bound Stone is registered common land over which there is a right of public access on foot.
The origin of Chesil Beach has been argued over for some time. Originally it was believed that beach material was from the Budleigh Salterton pebble beds to the west and later from Portland to the south east. The differences between the pebbles on the beach and nearby sources is now put down to the Flandrian isostatic sea level rise, so the feature could also be considered a barrier beach or bar, that happens to connect the mainland to an island rather than a 'true' tombolo. Normally, tombolos are created due to the effects of the island on waves (through refraction) and to sediment transport, which usually produces a beach perpendicular to the mainland rather than parallel to it.
Fossils occur all along the landward shore of the Fleet and along the landward side of Chesil Beach from Abbotsbury to West Bay. The main site is at Burton Bradstock.
There have been many shipwrecks on Chesil Beach, particularly during the age of sail. The beach was particularly dangerous within the English Channel, as it forms an extended lee shore during south-westerly gales. A ship coming up the Channel had to clear Portland Bill to be safe, but the wind and tide would be pushing it northwards into Lyme Bay. When sailing ships were common, a strong string of coastguards were based along the beach, with lookouts and cottages at Chiswell, Wyke Regis, Chickerell, Langton Herring, Abbotsbury, East Bexington, Burton Bradstock and West Bay. At present there are no manned stations along the beach, as coverage is provided when required from Portland Coastguard.
The local fishermen, particularly at Portland, developed a purpose-built vessel to withstand the sea actions of Chesil Beach. The boat, known as a Lerret, is a double-ended open fishing boat - 16–17 feet long - used for seine net fishing. It is usually rowed by four people with a fifth to steer and deploy the net.
Much of the villages Fleet and Chiswell were destroyed in the great storm of 1824. Over the centuries Chiswell had battled with the sea and was regularly flooded during rough winter storms. In the storms the sea would pour through the upper part of the bank, and for this reason plans to drain the Fleet were abandoned in 1630. The great storm of November 1824 struck the village with disastrous results - an event from which Chiswell would never fully recover. Since then various defences have been set-up to aid the village, notably the sea wall and promenade which commenced work in 1958, and was completed in 1965.
The Weymouth to Portland Railway line was opened in 1865, and built along the southern end of the beach. It closed to passengers in 1952 and finally closed to all traffic in 1965. The line included a viaduct across Ferry Bridge. Over the last 150 years there have been a number of proposals to built a line from Weymouth to Bridport running the length of Chesil Beach. A line was built from Upwey to Abbotsbury but could not be continued through lack of money. A line was also built from Maiden Newton to Bridport and then onwards to West Bay. A more recent proposal was to build a light railway between Weymouth and West Bay.
A rifle range, built around 1907, is situated on Chesil Beach, near Ferry Bridge. It had 100 yard increments up to 800 yards, and some remains of this structure can still be seen today. The Royal Navy operated a minesweeping trials range off West Bexington for many years following World War II. It was abandoned in the mid-1980s. The cables came ashore under the beach at the West Bexington car park, and today the range control building can still be seen behind the car park, while one of the theodolite stations is located near the entrance to the Cogden Beach car park.
The Fleet Lagoon
From West Bay to Cliff End the beach is piled up against the cliff. At Cliff End a hollow forms behind the beach and at Abbotsbury a stretch of saline (or brackish) water called the Fleet Lagoon begins. The Fleet is home to many wading birds and Abbotsbury Swannery, and fossils can be found in the sand and mud. The Fleet connects to Portland Harbour at Ferry Bridge. Initially a ferry boat was used to connect Portland to the mainland, until the first bridge was constructed in 1839. An iron bridge replaced this in 1896, and this was in turn replaced with a concrete bridge in 1985.
Both Chesil Beach and the Fleet Lagoon are a Site of Special Scientific Interest, and the view of the beach from Abbotsbury has been voted by Country Life magazine as Britain's third best view. The Fleet Lagoon and Chesil Beach feature in the novel Moonfleet by J. Meade Falkner (1898), in which the village of Moonfleet is based on the real village of East Fleet.
An arrangement of nets and poles to lure ducks into a closed area of netting is a decoy located within Abbotsbury Swannery. It was originally installed to provide food for the local monks, but is now used to catch ducks for ringing. It may be the oldest surviving decoy in England. Located in the Upper Fleet, within Abbotsbury Swannery, is Bum Point, and adjacent to this is an artificial island known as Tern Island, which was created to provide a nesting site for common terns.
The lagoon is a designated bass nursery area, and the species are frequently seen on an underwater camera connected to the Chesil Beach Visitor Centre. As such angling for the fish is only permitted in the lower Fleet area, from the Narrows to Ferrybridge and only from the shore. However this has also been discouraged by the Southern-IFCA (Inshore Fisheries and Conservation Authority) as a conservation measure. A shallow draft boat, named the Fleet Observer, featuring a transparent bottom, takes visitors around the lower Fleet to observe the wildlife above and below the water.
The main site of the Wyke Regis Training Area is found to the west of the Wyke Regis village, where it lies on the north side of the Fleet. This site, a bridging camp, was constructed in 1928 by Royal Engineers. Since then the site has been in continuous use for the training of Royal Engineers, amongst other armed forces, including both regular and reserve forces in the construction of both bridges and ferries, along with other types of military training. The Bridging Camp's inner training area allows Sappers to hone their skills on everything from raft building to familiarising themselves with state of the art weaponry. Due to the close proximity of the lagoon, water based training is held there.
A commercial oyster farm is situated on the sandbanks on the north side of the lower Fleet. The species farmed is the Pacific oyster, rather than the local oyster, and the farm racks are always visible at low tide.
At Seabarn, a 68 metre high hill located in the mid-Fleet, between Butterstreet Cove and Herbury, is a disused control tower and landing pad for the navy helicopter firing range in Lyme Bay. The range was closed when the Navy left Portland in 1995. There are also the remains of an anti-aircraft battery from the Second World War.
Due to the bird nesting season from 1 April until the end of August, access along, and to all parts of the beach from the Portland boundary stone to Abbotsbury is not permitted. Additionally access to the Fleet slope of the beach from Wyke to Abbotsbury is not permitted at any time in effort to protect and conserve the delicate environment. The Upper Fleet has some parts restricted to protect sensitive habitats.
The little egret, Egretta garzetta, once a rare visitor to the UK, but is now regularly seen along the shores of the Fleet. The scaly cricket, a small insect, is only found at three sites in the UK, including Chesil Beach. Two species of eelgrass are found in the Fleet: Zostera marina and Zostera Noltii. These species both grow submerged in the shallow waters of the mid and upper Fleet, where large quantities die off in the early autumn.
Chesil Beach is a popular location for sea angling, with access at Chiswell, Ferry Bridge, Abbotsbury, Cogden, Burton Bradstock and West Bay. Angling is also allowed in the lower Fleet from the shore. Commercial fishing, which often involved seine nets, has now virtually disappeared from Chesil Beach compared with the level of activity a century ago. Within the Fleet there is still a small controlled fishery for eels using fyke nets. The grey mullet is a common fish of the Fleet, occurring in large numbers along its entire length.
In 1971, the Japanese seaweed, Sargassum muticum, arrived in Britain, where it first appeared in the Isle of Wight. However in the following years it spread along the south coast to the Fleet. It soon dominated the environment despite a number of attempts to limit its impact. It has since died back to a much lower level of occupancy in the Narrows and lower Fleet, however the current amount of growth is often dependent on a number of factors and as such varies from year to year.
Due to issue with litter, both natural and man-made, brought to the beach by south-westerly gales, regular litter picks are organised, which involves volunteers to help alleviate the problem. A boom is in place at Ferry Bridge to minimise the impact on the Fleet of any oil pollution from within Portland Harbour.
Chesil Beach is susceptible to oil pollution from accidents in Lyme Bay. If the oil gets into the pebbles it would prove impossible to remove. There is also a danger of oil getting into the Fleet from an accident in Portland Harbour. A boom is available to place across the entrance at Ferrybridge to minimise the impact on the Fleet
Second World War defences
Because of the low population density of nearby areas, and their proximity to the naval base on Portland, the beach and the Fleet were used as an experimental bombing range by the RAF before and during World War II. Additionally during the war the beach was used for machine gun training and Highball bouncing bomb testing.
The Second World War defences constructed on and around Chesil Beach have been documented, and various defences still remain today, although some have been demolished or destroyed by the sea.
A double row of anti-tank blocks divides the beach near Abbotsbury, where the Fleet Lagoon begins. Most of the seaward blocks have been destroyed, but the parallel lines of blocks on the landward side still survive in good condition. Within the same spot are two remaining Type 26 pillboxes, which were originally of four pillboxes associated with the blocks. The pillboxes were constructed in 1940 and were situated within the Abbotsbury Defence area, which at this time, was manned by the 6th Battalion Durham Light Infantry. Both structures remain half buried in the beach and tilted at an angle. An anti-tank ditch was located within this area, behind Chesil Beach.
An observation post still exists on the landward side of the Fleet, with the open front facing Chesil Beach.
The portion of the beach to the east of the anti-tank division, in front of Fleet Lagoon, had no passive defences against a landing, whereas the beach to the west was protected with miles of Admiralty scaffolding with anti-tank ditches and minefields and flame fougasse installations a little further inland. There were many pillboxes.
The Jurassic Coast stretches over a distance of 155 kilometres (96 mi) from Orcombe Point near Exmouth, in the west, to Old Harry Rocks on the Isle of Purbeck, in the east. The coastal exposures along the coastline provide a continuous sequence of Triassic, Jurassic and Cretaceous rock formations spanning approximately 185 million years of the Earths history. The localities along the Jurassic Coast includes a large range of important fossil zones.
