Swildon's Hole

Priddy is a village in Somerset, England in the Mendip Hills, close to East Harptree and 4 miles (6 km) north-west of Wells. It is in the local government district of Mendip. The village lies in a small hollow near the summit of the Mendip range of hills, at an elevation of nearly 1,000 feet (300 m) above sea-level, and has evidence of occupation since neolithic times. There are remains of lead mining activities and caves in the limestone beneath the village. It is the venue for the annual Priddy Folk Festival. The Sheep Fair, was last held in 2013.

Priddy Nine Barrows Cemetery and Ashen Hill Barrow Cemetery are a collection of round barrows, dating from the Bronze Age, near Priddy in the English county of Somerset. They are designated as ancient monuments.The barrows sit on crests of land at either end of a field in an area of the Mendip Hills with several Neolithic remains. They are assumed to be related to the Priddy Circles which lie 750 metres (2,460 ft) to the north. Ashen Hill consists of six bowl barrows and two bell barrows aligned east to west while Priddy Nine Barrows divided into one group of seven round barrows and another pair slightly separated from the others. Excavations in 1815 uncovered cremation burials and grave goods. A geophysical magnetometry survey suggested that there may have been three further barrows.

Eastwater Cavern is a cave near Priddy in the limestone of the Mendip Hills, in Somerset, England. It is also known as Eastwater Swallet. It was first excavated in April 1902 by a team led by Herbert E. Balch composed of paid labourers and volunteers from the Wells Natural History Society. Progress was initially slow, but by February 1903 Balch and Willcox had discovered substantial passage, following the streamway down to the bottom of the cave. Dolphin Pot was dug in 1940 by the Wessex Cave Club, with Primrose Pot following in 1950. West End series was the most recent significant discovery, in 1983.On 28 August 1910 severe flooding rendered the boulder ruckles unstable, and the bottom of the cave was not reached again for another three years. The cavern was the site of a fatal accident in 1960, when Alan Hartnell was hit by rock-fall. Several areas of the boulder chokes remain unstable.Dolphin ladder pitch also suffered a rock fall and was blocked by a sofa-sized boulder in 1959, but the route was re-opened in 1966.The water resurges at Wookey Hole Caves 4 kilometres (2.5 mi) to the south, and 180 metres (590 ft) below the cave entrance.

Sandpit Hole and Bishop's Lot (grid reference ST531498) is a 1.8 hectare geological Site of Special Scientific Interest near Ebbor Gorge in Somerset, notified in 1987. This site consists of two of the largest isolated depressions, known as dolines, occurring in the Mendip limestone area, and both appear to have been formed by the limestones being dissolved by subterranean waters and the overlying rocks then collapsing into them.

Chancellor's Farm (grid reference ST525525) is a 34.2-hectare (84.6 acre) biological Site of Special Scientific Interest just north of Priddy in the Mendip Hills, Somerset, notified in 1984. The site, which is close to the Yoxter military range, is operated as a restricted-access nature reserve by the Somerset Wildlife Trust.This site provides outstanding examples of some of the grassland communities associated with the higher parts of the Mendip plateau. The soils include a mixture of wind-deposited silts and weathered material from the parent Carboniferous Limestone. The grassland is a type characterised by Sweet Vernal Grass (Anthoxanthum odoratum), Red Fescue (Festuca rubra), Common Bent (Agrostis capillaris), Pignut (Conopodium majus) and Sorrel (Rumex acetosa). Of particular interest is the abundance of Common Bluebell (Hyacinthoides non-scripta), a species rare outside woodland habitats in Somerset.The site includes extensive remains of lead mining from the medieval period to the early 18th century, with some evidence of iron mining in the north east corner of the site.

Priddy Caves (grid reference ST540505) is an Area: 67.6 hectare (167.0 acre) geological Site of Special Scientific Interest at Priddy in the Mendip Hills, Somerset, notified in 1965. The entrance to St Cuthbert's Swallet is incorporated in the adjacent Priddy Pools SSSI. The Priddy Caves System contains about 16 km of surveyed cave passages divided between a number of major and minor networks. All the caves are sink hole systems, fed by sink holes at the ground surface. In all the caves, the detailed disposition and form of the passages can be seen clearly to have followed marked lines of natural weakness in the rocks. The three largest networks, Swildon's Hole, St Cuthbert's Swallet and Eastwater Cavern exceed 100 metres in depth. Swildon's Hole is a world-famous example of a shallow depth phreatic cave, which shows a very well developed dendritic pattern of drainage and contains extensive clastic and stalagmite fills. Hunter's Hole is an excellent example of a shaft complex draining a closed depression. This cave differs from the others at Priddy in apparently not having formed as a stream swallet. Cave sediments found within the systems, together with the information which can be deduced from the physical form of the caves, provide geologists with the means to obtain a better understanding of the geological evolution of southern Britain during the ice ages.

Priddy Circles are a linear arrangement of four circular earthwork enclosures near the village of Priddy on the Mendip Hills in Somerset, England. The circles have been listed as Scheduled Ancient Monuments, and described as 'probable Neolithic ritual or ceremonial monuments similar to a henge'.The southernmost Priddy Circle falls on adjoining land to a house and stables that are owned by retired businessman Roger Penny. In 2012 Penny was fined £10,000 after the earthwork was damaged by work he had permitted.

Priddy Pools (grid reference ST545510) is a 52.7-hectare (130-acre) geological Site of Special Scientific Interest at Priddy in the Mendip Hills, Somerset, notified in 1972. The pools provided the water supply for the Priddy Mineries which is now a Nature Reserve.

St Cuthbert's Swallet is the second longest, and most complex, cave on the Mendip Hills, in Somerset, England. It forms a major part of the Priddy Caves system and water entering this swallet re-emerges at Wookey Hole. St Cuthbert's Swallet is part of, and lies underneath, the Priddy Pools Site of Special Scientific Interest.It is named because of its location in the St Cuthbert Out parish of Wells, and was originally called St Cuthbert's Pot.

Priddy Mineries (grid reference ST547515) is a nature reserve previously run by the Somerset Wildlife Trust. It is in the village of Priddy, on the Mendip Hills in Somerset. The reserve lies 3 miles north of Wells and 1.5 miles east of the village of Priddy. It is a site of 50 ha (123 acres) and is part of the Priddy Pools Site of Special Scientific Interest (SSSI). It is mostly grassland / heather mosaic with an area of valley mire and some nutrient-poor pools. The site is one of the beauty spots of Mendip partly due to these pools with the changing colours of the vegetation and the pines and the heather slopes. It is adjacent to Stock Hill woodland, and one of the paths form part of the long distance national footpath, the Monarch's Way. There are wide range of plant and small animal species. More than 20 species of dragonflies have been recorded, most of them breeding on site. In particular this is the only site in the Mendips for the Downy Emerald. There are numerous species of water bug including Water stick-insect (Ranatra linearis) and also all British species of amphibian, except for the Natterjack Toad, in good breeding numbers. The site was worked for lead for many centuries, probably 2000 years until 1908, and the earlier workings were obliterated by those of the Victorians which left a legacy of pools, mounds and spoil heaps. The buddle pits and condensation flues are the remains of the Waldegrave lead works of that time. The site is of great interest to industrial archaeologists and also to cavers on account of the existence of Waldegrave swallet (opened 1934) and the possible rediscovery of Five Buddles Sink or Thomas Bushell’s Swallet (named after the man who first discovered it).A barrow or Tumulus can be found in the northern part of the Reserve.

Ebbor Gorge is a limestone gorge in Somerset, England, designated and notified in 1952 as a 63.5-hectare (157-acre) biological Site of Special Scientific Interest in the Mendip Hills. It was donated to the National Trust in 1967 and is now managed by Natural England as a national nature reserve. The gorge was cut mostly into the Clifton Down Limestone, part of the Lower Carboniferous Pembroke Group, by water. The site was occupied by humans in the Neolithic Era and their tools and flint arrow heads have been discovered, along with pottery from the Bronze Age. There are also fossils of small mammals from the Late Devensian. The nature reserve provides a habitat for a variety of flora and fauna, including flowers, butterflies and bats.

Hunter's Hole (or Hunters' Hole) is a cave in the Mendip Hills in Somerset, England. It is behind a pub, known as the Hunters Lodge Inn just outside Priddy where visitors can park. It is accessed via a permanent ladder, about 100m behind the pub in a small dip between some trees. The main cave was first entered after digging by Wessex and BEC cavers in 1954.The cave itself consists of a series of shafts down into the main chamber, named the "railway tunnel". Due to the cave mainly being the ascent and descent, it is used to practise single rope technique (SRT). It is part of the Priddy Caves Site of Special Scientific Interest and described as "an excellent example of a shaft complex draining a closed depression. The roof of the main shaft shows a variety of features such as soil and boulder bridges and scalloped and speleothem lined rifts, all draining the surface depression. This cave differs from the others at Priddy in apparently not having formed as a stream swallet."
