Banwell Caves (grid reference ST383588 ) are a 1.7-hectare geological and biological Site of Special Scientific Interest near the village of Banwell, North Somerset, England notified in 1963.
The site comprises two caves, called 'Banwell Bone Cave' and 'Banwell Stalactite Cave', which lie within the grounds of a large house, at the western end of Banwell Hill. The caves contain barite deposits, which are found in greater abundance and variety here than at any other site in the Mendip Hills, and are used as a hibernation site by greater horseshoe bats (Rhinolophus ferrumequinum). [1]
The site also has several grottos and follies, including the Pebble summerhouse, Druid's Temple, an osteoicon (or bone repository) and Banwell Tower which was completed in 1840. [2]
The first cave to be discovered was the Stalactite Cave in 1757. This was opened in 1824 as a show cave to raise money for the local school. In an attempt to make access easier, a tunnel was dug into the hill during which the bone cave was discovered in 1825.
The estate was owned by George Henry Law as Bishop of Bath and Wells, who thought the bones which were found were those of animals drowned in the flood at the time of Noah's Ark described in the Book of Genesis. The bishop had paths and folly buildings created for visitors and built a small cottage, which later became his retirement home.
Since the 1970s, preservation and restoration work has been undertaken.
Banwell Bone Cave is 100 m (328 ft) long and 20 m (66 ft) deep. The Bone Cavern itself is 8 m (26 ft) high and wide and 20 m long. It is approached through an early 19th-century archway. [3] It contains an assemblage of bones of mammals (including bear, deer, ox, bison and reindeer) from the Pleistocene era (approximately 80,000 years ago). [4] [5] The cave has a large hole in the roof and is believed to have been used as a pitfall trap.
The Bone Cave was discovered in 1824 during attempts to drive a horizontal passage into the Stalactite Cave. Archaeological excavation was carried out by William Beard, with some of the bones being removed, but many being left in the cave in stacks. [5] [6]
Banwell Stalactite Cave is 240 m (787 ft) long and 75 m (246 ft) deep. Although no stream now runs through the cave, there is a deep lake in one of the chambers. [5] The Stalactite Cave was entered by miners in 1757, [4] and was a show cave between about 1824 and 1864. [7]
The 18-metre (59 ft) high, three-stage tower, which is also known as the Banwell Monument or Banwell Pepperpot, was built in 1840 from local lias stone with some decoration in Bath stone. During World War II, it was used as a lookout tower by the Home Guard. [2] By the 1960s it was in a poor state of repair and could no longer be seen above the growing treetops. Local conservation groups undertook conservation work, and it was reopened to the public in 1996. It is a Grade II listed building. [8]
Wookey Hole Caves are a series of limestone caverns, a show cave and tourist attraction in the village of Wookey Hole on the southern edge of the Mendip Hills near Wells in Somerset, England. The River Axe flows through the cave. It is a Site of Special Scientific Interest (SSSI) for both biological and geological reasons. Wookey Hole cave is a "solutional cave", one that is formed by a process of weathering in which the natural acid in groundwater dissolves the rocks. Some water originates as rain that flows into streams on impervious rocks on the plateau before sinking at the limestone boundary into cave systems such as Swildon's Hole, Eastwater Cavern and St Cuthbert's Swallet; the rest is rain that percolates directly through the limestone. The temperature in the caves is a constant 11 °C (52 °F).
The Mendip Hills is a range of limestone hills to the south of Bristol and Bath in Somerset, England. Running east to west between Weston-super-Mare and Frome, the hills overlook the Somerset Levels to the south and the Chew Valley and other tributaries of the Avon to the north. The hills give their name to the local government district of Mendip, which administers most of the area. The higher, western part of the hills, covering 198 km2 (76 sq mi) has been designated an Area of Outstanding Natural Beauty (AONB), which gives it a level of protection comparable to a national park.
Burrington Combe is a Carboniferous Limestone gorge near the village of Burrington, on the north side of the Mendip Hills Area of Outstanding Natural Beauty, in North Somerset, England.
Banwell Ochre Caves are a 12.46-hectare geological Site of Special Scientific Interest near the village of Banwell, North Somerset, notified in 1983.
Wade Browne's Folly is a folly tower sitting within a 39.9 hectare biological and geological Site of Special Scientific Interest (SSSI) near the village of Bathford in Somerset, notified in 1974: the site itself is known as the Farleigh Down Stone Quarry, and is managed as a nature reserve by the Avon Wildlife Trust (AWT). The tower was built in 1848 and is a Grade II listed building.
Lamb Leer is a 14.59 hectare geological Site of Special Scientific Interest between East Harptree and Priddy in the Mendip Hills, Somerset, notified in 1983. The cavern is a fragment of a very ancient major cave system which now contains one of the largest chambers in the Mendip Hills.
Thrupe Lane Swallet is a 0.5 hectares geological Site of Special Scientific Interest in Somerset, notified in 1992. It is also a Geological Conservation Review site.
Gough's Cave is located in Cheddar Gorge on the Mendip Hills, in Cheddar, Somerset, England. The cave is 115 m (377 ft) deep and is 3.405 km (2.12 mi) long, and contains a variety of large chambers and rock formations. It contains the Cheddar Yeo, the largest underground river system in Britain.
The caves of the Mendip Hills are formed by the particular geology of the Mendip Hills: large areas of limestone worn away by water makes it a national centre for caving. The hills conceal the largest underground river system in Britain.
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.
Goatchurch Cavern is a cave on the edge of Burrington Combe in the limestone of the Mendip Hills, in Somerset, England.
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.
Stoke Lane Slocker is a cave near Stoke St Michael, in the Carboniferous Limestone of the Mendip Hills, in the English county of Somerset.
The Mendip Way is an 80-kilometre (50 mi) long-distance footpath across the Mendip Hills from Weston-super-Mare to Frome. It is divided into two sections.
Rod's Pot is a limestone cave above Burrington Combe in the Mendip Hills, in Somerset, England.
Banwell is a village and civil parish on the River Banwell in the North Somerset district of Somerset, England. Its population was 2,919 according to the 2011 census.
The Cranmore Tower is a 45 metres (148 ft) tall 19th century folly in the parish of Cranmore, Somerset, England. The site is 280 metres (919 ft) above sea level, and is the highest point on the Mendip Way.
The Grade I listed buildings in Somerset, England, demonstrate the history and diversity of its architecture. The ceremonial county of Somerset consists of a non-metropolitan county, administered by Somerset County Council, which is divided into five districts, and two unitary authorities. The districts of Somerset are West Somerset, South Somerset, Taunton Deane, Mendip and Sedgemoor. The two administratively independent unitary authorities, which were established on 1 April 1996 following the breakup of the county of Avon, are North Somerset and Bath and North East Somerset. These unitary authorities include areas that were once part of Somerset before the creation of Avon in 1974.
William Beard was a British bone collector.
Reservoir Hole is a cave in Cheddar Gorge in Somerset, southwest England. It contains what is believed to be the largest chamber yet found under the Mendip Hills.
