Clearwell Caves, at Clearwell in the Forest of Dean, Gloucestershire, England, is a natural cave system which has been extensively mined for iron ore. It now operates primarily as a mining museum.
The caves are part of a Natural England designated Site of Special Scientific Interest and the notification includes parts of Clearwell along with Old Bow, Lambsquay and Old Ham mine complexes. [1]
Clearwell Caves are a collection of six mines: Clearwell, Old Ham, Lambsquay, Old Bow, Oak Pit and New Dun, covering approximately 250 acres. The interconnected cave systems were formed by underground streams from around 180 million years ago. [2] They have been mined originally for ochre, then for iron ore from Iron Age times Circa 100BC increasing from Roman times [2] and extensively during the 19th century, which considerably enlarged and extended the network of natural caverns.
Ochre has been mined here for even longer. [2]
The nearby scowles around the Forest of Dean, including Puzzlewood represent shallow surface mining, where surface working later became entrances to these deeper mines as early miners worked beyond daylight to follow the ore.
Clearwell Caves are still worked to produce coloured ochres for use by artists as natural pigments. These are washed and milled for sale in the mine's ochre workshop. A range of ochre colours are available from the mine shop, from golden yellow to English Reds. Clearwell is also known as one of the few locations in the world where natural deep purple ochre, particularly caput mortuum is found.
Ten well lit chambers have been made easily accessible to visitors, with displays throughout. There is a small museum, shop and café. A network of much deeper workings can be visited in the presence of an experienced guide and with appropriate caving equipment for safety. The upper caves are open to the general visitor.
Parts of the caves were originally opened to the public by Ray Wright (1930-2015) from 1968 and are now managed by his son Jonathan Wright, who is a Freeminer, still mining ochre from the workings. The caves have been used as a Santa's Grotto at Christmas time for many years, for Easter egg hunts and in the summer barbecues, music concerts and theatrical performances. One chamber is large enough to permit underground functions, including an annual Halloween Party hosting over 300 people. Parts of the Doctor Who episodes "The Christmas Invasion" (2005), "The Satan Pit" (2006) and "Time of the Angels" / "Flesh and Stone" (2010) were filmed in the caves.
All the underground scenes of the BBC series "Merlin", were filmed in the Caves. The Caves have also long been used for filming science fiction scenes, such as in Blake's 7 - Horizon . The Caves featured substantially in the children's series "The Changes", "The Jensen Code" and "Kidnapped" among many others. More recently the caves have been featured in episodes of Britannia, Cursed, His Dark Materials, Willow (TV series), The Winter King and Pig Man's house in the channel 4 comedy series - The Change.
frequent claims of paranormal phenomena at the Caves have been made over the years. These include reported sightings, the sound of metal clanging in the distance, [3] and many reported sightings of an old miner, the sound of footsteps and pick axes working.
The caves were used as the interior for the Sycorax spaceship in the Doctor Who Christmas special, The Christmas Invasion in 2005. [4]

Freeminer is an ancient title given to coal or iron miners in the Forest of Dean, Gloucestershire, England, who have earned the right to mine personal plots, known as gales.
Mine exploration is a hobby in which people visit abandoned mines, quarries, and sometimes operational mines. Enthusiasts usually engage in such activities for the purpose of exploration and documentation, sometimes through the use of surveying and photography. In this respect, mine exploration might be considered a type of amateur industrial archaeology. In many ways, however, it is closer to caving, with many participants actively interested in exploring both mines and caves. Mine exploration typically requires equipment such as helmets, head lamps, Wellington boots, and climbing gear.
Littledean Hall is a country house in the village of Littledean, Gloucestershire, England. It has been described as one of the most haunted houses in England and is thought to be the oldest house in the United Kingdom which is still occupied. Saxon and Celtic remains have been uncovered in the cellars. Part of the house is designated an SSSI as it is a proven breeding roost for the Greater Horseshoe Bat (Rhinolophus ferrumequinum).

Mining in the Upper Harz region of central Germany was a major industry for several centuries, especially for the production of silver, lead, copper, and, latterly, zinc as well. Great wealth was accumulated from the mining of silver from the 16th to the 19th centuries, as well as from important technical inventions. The centre of the mining industry was the group of seven Upper Harz mining towns of Clausthal, Zellerfeld, Sankt Andreasberg, Wildemann, Grund, Lautenthal und Altenau.
The Forest of Dean Coalfield, underlying the Forest of Dean, in west Gloucestershire, is one of the smaller coalfields in the British Isles, although intensive mining during the 19th and 20th centuries has had enormous influence on the landscape, history, culture, and economy of the area.
