Harptree Combe (grid reference ST561558 ) is a 13.63-hectare (33.68-acre) [1] Site of Special Scientific Interest (SSSI) near East Harptree notified in 1954. "Combe" or "coombe" is a West Country word meaning a steep-sided valley. It is also the site of a 19th-century aqueduct and is overlooked by the site of a castle dating from around 1100.
In August 2009, 22.67 acres (9.17 ha) of the Combe were purchased by Alan Sheppard for £60,000. He became the third owner since 1805, the previous sale being in 1922. [2]
Appleyard's Feather-moss Brachythecium appleyardiae was described as new to science from this site in 1981, although doubt has been cast on the validity of the species as a result of genetic evidence published in 2005 which suggests that this moss is in fact a member of the widespread moss species Scleropodium cespitans. [3]
Grassy clearings within the combe are the only site in Avon where the nationally scarce Spreading Bellflower Campanula patula is found. The species was first found here in 1829. [4]
Harptree Combe is a narrow limestone gorge containing a variety of habitats, including Ash woodland, rough grassland, natural and artificial rock faces, and a small, marshy stream. The valley wood has been identified as an ancient woodland site, rich in tree and shrub species, and with a ground flora containing plants such as Herb Paris Paris quadrifolia), indicative of such undisturbed habitats. Several other uncommon or local plants, such as Small Teasel Dipsacus pilosus and Autumn Crocus Colchicum autumnale, also occur. The limestone rock exposures and aqueduct walls are location for many species of moss and fern, some of which, e.g. Rusty Beard-moss Didymodon ferrugineus (previously Barbula reflexa), Brown Beard-moss Didymodon spadiceus (previously Barbula spadicea) and Brittle Bladder-fern Cystopteris fragilis, are rare in Southern England. [5]
An aqueduct for Bristol water supply follows the line of the combe. It was completed in 1851, with James Simpson acting as the chief engineer, and it is still in use today. It consists of a wrought iron tube, which runs underground for 18 kilometres (11 mi), to Bristol Reservoirs but where it appears above ground it is supported by limestone piers and abutments. It is probably the oldest surviving example of such engineering and has been designated by English Heritage as a grade II listed building. [6]
The scanty ruins of Richmont Castle are just above the combe. The castle was besieged in 1138 when King Stephen captured it from Sir William de Harptree, a supporter of Queen Matilda's cause, in the civil war between the king and queen. The castle was also visited by King John in 1205. [7] The castle was demolished by its owner, Sir John Newton, in the reign of Henry VIII.
Wade and Wade in their 1929 book Somerset described it: "On an inaccessible tongue of land at the far end of the gorge are the remains of Richmont Castle, one of those lawless strongholds which in the days of Stephen were a terror to the country side. In 1138 it was strongly garrisoned by its owner, William de Harptree, on behalf of the Empress Matilda, but was taken by Stephen by the ruse of a feigned repulse. Now, only a fragment of the keep overlooks the glen." [8] Some earthworks are still visible but partially covered by the undergrowth.
Cheddar is a large village and civil parish in the English county of Somerset. It is situated on the southern edge of the Mendip Hills, 9 miles (14 km) north-west of Wells, 11 miles (18 km) south-east of Weston-super-Mare and 18 miles (29 km) south-west of Bristol. The civil parish includes the hamlets of Nyland and Bradley Cross. The parish had a population of 5,755 in 2011 and an acreage of 8,592 acres (3,477 ha) as of 1961.
The River Avon is a river in the southwest of England. To distinguish it from a number of other rivers of the same name, it is often called the Bristol Avon. The name 'Avon' is a cognate of the Welsh word afon, meaning 'river'.
The Kennet and Avon Canal is a waterway in southern England with an overall length of 87 miles (140 km), made up of two lengths of navigable river linked by a canal. The name is used to refer to the entire length of the navigation rather than solely to the central canal section. From Bristol to Bath the waterway follows the natural course of the River Avon before the canal links it to the River Kennet at Newbury, and from there to Reading on the River Thames. In all, the waterway incorporates 105 locks.
The Mendip Hills is a range of limestone hills to the south of Bristol and Bath in Somerset, England. Running from Weston-super-Mare and the Bristol Channel in the west to the Frome valley in the east, the hills overlook the Somerset Levels to the south and the Chew Valley and other tributaries of the Avon to the north. The highest point, at 325 metres above sea level, is Beacon Batch which is the summit area atop Black Down. The hills gave their name to the former local government district of Mendip, which administered most of the local area until April 2023. 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.
The Avon Gorge is a 1.5-mile (2.5-kilometre) long gorge on the River Avon in Bristol, England. The gorge runs south to north through a limestone ridge 1.5 miles (2.4 km) west of Bristol city centre, and about 3 miles (5 km) from the mouth of the river at Avonmouth. The gorge forms the boundary between the unitary authorities of North Somerset and Bristol, with the boundary running along the south bank. As Bristol was an important port, the gorge formed a defensive gateway to the city.
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.
East Harptree is a village and civil parish in Somerset, England. It is situated 5 miles (8.0 km) north of Wells and 15 miles (24.1 km) south of Bristol, on the northern slope of the Mendip Hills overlooking the Chew Valley. The parish has a population of 644. The parish includes the hamlet of Coley.
The Chew Valley is an affluent area in North Somerset, England, named after the River Chew, which rises at Chewton Mendip, and joins the River Avon at Keynsham. Technically, the area of the valley is bounded by the water catchment area of the Chew and its tributaries; however, the name Chew Valley is often used less formally to cover other nearby areas, for example, Blagdon Lake and its environs, which by a stricter definition are part of the Yeo Valley. The valley is an area of rich arable and dairy farmland, interspersed with a number of villages.
Leigh Woods is a 2-square-kilometre (0.77 sq mi) area of woodland on the south-west side of the Avon Gorge, close to the Clifton Suspension Bridge, within North Somerset opposite the English city of Bristol and north of the Ashton Court estate, of which it formed a part. Stokeleigh Camp, a hillfort thought to have been occupied from the third century BC to the first century AD and possibly also in the Middle Ages, lies within the reserve on the edge of the Nightingale Valley. On the bank of the Avon, within the reserve, are quarries for limestone and celestine which were worked in the 18th and 19th centuries are now derelict.
The North Somerset Levels is a coastal plain, an expanse of low-lying flat ground, which occupies an area between Weston-super-Mare and Bristol in North Somerset, England. The River Banwell, River Kenn, River Yeo and Land Yeo are the three principal rivers draining the area.

The tower was built in 1848 and is a Grade II listed building.
Goblin Combe is a dry valley in North Somerset which stretches for approximately 3½ km from Redhill, near Bristol International Airport on the A38, through to Cleeve on the A370. The combe is located at, and is a 52-hectare (128-acre) biological Site of Special Scientific Interest (SSSI) originally notified in 1999, with 9 hectares being managed as a nature reserve by the Avon Wildlife Trust. The Combe runs along the southern edge of a large woodland. "Combe" is the same as the Welsh word "cwm" which means valley.
