Speedwell Cavern

Treak Cliff Cavern is a show cave near Castleton in Derbyshire, England. It is part of the Castleton Site of Special Scientific Interest and one of only two sites where the ornamental mineral Blue John is still excavated (the other is the nearby Blue John Cavern). As part of an agreement with English Nature, the Blue John that can be seen in the show cave is not mined but it is extracted in small quantities from other areas of the cave and made into saleable items like bowls, jewellery, and ornaments.The cave comprises two sections, the Old Series, discovered by lead miners in the 18th century, and the New Series, discovered during blasting in the 1920s. Only the Old Series contains Blue John, but the New Series is well decorated with flowstone, stalagmites, and stalactites. Three human skeletons and flint implements from the Neolithic era were found in a small cave nearby in 1921.

Winnats Pass (or Winnats, as shown on some Ordnance Survey maps) is a hill pass and limestone gorge in the Peak District of Derbyshire, England. The name is a corruption of 'wind gates' due to the swirling winds through the pass. It lies west of the village of Castleton, in the National Trust's High Peak Estate and the High Peak borough of Derbyshire. The road winds through a cleft, surrounded by high limestone ridges. At the foot of the pass is the entrance to Speedwell Cavern, a karst cave accessed through a flooded lead mine, and which is a popular tourist attraction.In the 1930s, Winnats Pass was the location used for annual access rallies in support of greater access to the moorlands or the Peak District, around the time of the Mass Trespass of Kinder Scout. At their peak these were attended by up to 10,000 people.The permanent closure of the main A625 road at Mam Tor in 1979 due to subsidence has resulted in Winnats Pass being heavily used by road traffic. However, the narrowness of the road and its maximum gradient of over 28% (1 in 3+1⁄2) has caused it to be closed to buses, coaches and vehicles over 7.5 tonnes in weight. The road regularly features in the Tour of the Peak cycle race each autumn.

Titan is a natural cavern near Castleton in the Derbyshire Peak District, and is the deepest shaft of any known cave in Britain, at 141.5 metres (464 ft). The existence of Titan was revealed in November 2006, following its discovery on 1 January 1999 after cavers discovered connections from the James Hall Over Engine Mine to both Speedwell Cavern and Peak Cavern. Previously, the deepest known underground shaft in Britain had been Gaping Gill on the slopes of Ingleborough in the Yorkshire Dales. A group of Peak District cavers discovered the shaft after finding an account by an 18th-century academic, James Plumtree, in a university library. Initial explorations in the James Hall Over Engine Mine led to the discovery of a large shaft named Leviathan, before further excavations revealed the existence of Titan.

The A625 is a rural road which runs through north Derbyshire and the Peak District in England.

Odin Sitch is a stream in the Derbyshire Peak District, originating near Odin Mine on the slopes on Mam Tor in Castleton. The stream meets Peakshole Water to the north of Castleton.

Goosehill Hall is an 18th-century Grade II listed country hall on the outskirts of Castleton, Derbyshire.

Odin Mine is a disused lead mine in the Peak District National Park, situated at grid reference SK133835. It lies on a site of 25 hectares near the village of Castleton, England. It is the oldest documented mine in Derbyshire and is thought to be one of the oldest lead mines in England. The mine is a Scheduled Ancient Monument and has biological and geological significance within the Castleton Site of Special Scientific Interest.

The Blue John Cavern is one of the four show caves in Castleton, Derbyshire, England. The others are Peak Cavern, Treak Cliff Cavern and Speedwell Cavern.

The Peak Cavern, also known as the Devil's Arse, is one of the four show caves in Castleton, Derbyshire, England. Peakshole Water flows through and out of the cave, which has the largest cave entrance in Britain.

Peakshole Water is a stream in the Derbyshire Peak District named after its source, Peak Cavern. It flows through the village of Castleton to join the River Noe in nearby Hope. Despite its name, much of its flow actually emerges from the Russet Well, a resurgence in a garden on the east side of the gorge below the main Peak Cavern entrance, described as the "main resurgence of the Castleton area", which drains a series of swallets on the other side of the Pennine watershed below Rushup Edge. The resurgence has been explored by cave divers to a depth of 82 feet (25 m) but further exploration was halted by a constriction.The River Noe flows into the Derbyshire Derwent, which in turn leads to the River Trent and thence to the Humber estuary and the North Sea. The stream once powered a corn mill in Castleton which remained in use until about 1920. The 10–12ft diameter water wheel survived until the 1950s. Little is left of the mill, apart from the wheel pit and the mill pond. A public footpath leads from Castleton past the mill and follows close to the stream as far as Pindale Road south of Hope. The stream has one main tributary, Odin Sitch, which rises above Odin Mine on the slopes of Mam Tor and joins Peakshole Water north of the visitor centre in Castleton.

Cave Dale (sometimes spelt Cavedale) is a dry limestone valley in the Derbyshire Peak District, England. It is located at grid reference SK149824. The northern end of the dale starts at the village of Castleton where the valley sides are almost perpendicular and over 50 metres (160 ft) in height. The dale rises gently after leaving Castleton for approximately 200 metres (220 yd) before becoming steeper culminating in a fine viewpoint down the dale taking in Peveril Castle with Lose Hill behind (see picture). After the viewpoint the dale swings west and levels out with gentle gradients, becoming just a shallow depression as it peters out onto the open pastureland between Castleton and Chapel-en-le-Frith.Cave Dale was initially formed by glacial meltwater carving a deep narrow valley in the local soluble limestone. The river then found a route underground leaving a dry valley with caverns underneath. Later on the caverns below Cave Dale collapsed making the valley even deeper and gorge-like at the northern end. The Castleton entrance to Cave Dale had a narrow natural arch as recently as 200 years ago, a relic of the roof collapse. The lower slopes of the dale have large amounts of scree, frost on the higher limestone cliffs having caused the rock to shatter. Halfway up the valley is an outcrop of basaltic lava with a few small columns. Although relatively small, the lava forms a hydrological barrier, creating an 'umbrella' effect in Peak Cavern below, preventing speleothem production beneath the bed. A bridleway runs the entire length of the dale, part of the Limestone Way footpath which travels 80 kilometres from Castleton to Rocester in Staffordshire. Cave Dale is accessed through a narrow rocky opening almost from the centre of Castleton, and Peveril Castle is seen high up on the almost vertical western slopes. The Normans chose this site because the steep sides of Cave Dale gave a natural defence and good lookout. The chambers and caves of Peak Cavern run directly below Cave Dale and any small streams in the dale quickly disappear into the ground down limestone fissures and into the caverns beneath. Mineral veins can also be seen within the limestone of the dale. The cliffs at the northern end of Cave Dale are used by rock climbers and there are several routes in the Very Severe category. There are several small caves or old lead mines within the dale's limestone walls, one being larger than the rest with bars preventing access, as it is the ventilation fan outlet for Peak Cavern. Cave Dale's steep north-facing grassy slopes are damp and bryophyte-rich and are dominated by oat grass (Trisetum flavescent) and sheep's fescue (Festuca ovina). Lesser meadow-rue (Thalictrum minus) grows extensively on ledges in the dale.At the southwestern extremity of the dale as it merges into the moorland between Castleton and Peak Forest are the remains of several old lead mines. The Hazard Mine lies at grid reference SK136812, and was one of the major mines of the area. Over 5000 tonnes of lead ore were mined and the workings once went down to 700 feet (210 m), though the main shaft is now only 80m deep after internal collapses. The Hollandtwine Mine lies 250 metres (820 ft) to the east but the shaft top was destroyed and buried during fluorspar quarrying in the 1990s, and access is no longer possible. Drainage from both mines went directly into Peak Cavern.In 1983 Cave Dale was the scene of the murder of a 21-year-old Manchester Polytechnic student, Susan Renhard. Norman Smith, a local 17-year-old, was subsequently jailed for life at Nottingham Crown Court in 1984. Cave Dale features in the films The Princess Bride (1987) and The Other Boleyn Girl (2008).

Peveril Castle (also Castleton Castle or Peak Castle) is a ruined 11th-century castle overlooking the village of Castleton in the English county of Derbyshire. It was the main settlement (or caput) of the feudal barony of William Peverel, known as the Honour of Peverel, and was founded some time between the Norman Conquest of 1066 and its first recorded mention in the Domesday Survey of 1086, by Peverel, who held lands in Nottinghamshire and Derbyshire as a tenant-in-chief of the king. The town became the economic centre of the barony. The castle has views across the Hope Valley and Cave Dale. William Peveril the Younger inherited his father's estates, but in 1155 they were confiscated by King Henry II. While in royal possession, Henry visited the castle in 1157, 1158, and 1164, the first time hosting King Malcolm IV of Scotland. During the Revolt of 1173–1174, the castle's garrison was increased from a porter and two watchmen to a force led by twenty knights shared with the castles of Bolsover and Nottingham. The Earls of Derby had a claim to the Peveril family's estates through marriage, and in 1199 William de Ferrers, the fourth earl, paid 2,000 marks for the Peak lordship, although the castle remained under royal control. The closest Peveril Castle came to seeing battle was in 1216, when King John gave the castle to William de Ferrers, but the castellan refused to relinquish control. Although they were both John's supporters, the king authorised the earl to use force to evict the castellan, who eventually capitulated, although there is no evidence that the castle was assaulted. In 1223 the castle returned to the Crown. In the 13th century there were periods of building work at the castle, and by 1300 its final form had been established. Toward the end of the 14th century, the barony was granted to John of Gaunt, Duke of Lancaster. Having little use for the castle, he ordered some of its material to be stripped out for re-use, marking the beginning of its decline. From the time of John of Gaunt to the present day, the castle has been owned and administered by the Duchy of Lancaster. Peveril Castle became less important administratively, and by 1609 it was "very ruinous and serveth for no use". In the 19th century, Sir Walter Scott featured the castle in his novel Peveril of the Peak. The site is situated in a national park, and cared for by English Heritage. Peveril Castle is protected as a scheduled monument and a Grade I listed building.
