The North Downs Tunnel, also known as the Blue Bell Hill Tunnel, is a railway tunnel that carries High Speed 1 through the North Downs, at Blue Bell Hill near Maidstone in Kent, south-east England. The tunnel is 3.2 kilometres (2 mi) long, with an internal diameter of 12 metres (40 ft) and a cross-sectional area (CSA) of 150 square metres, and descends to a depth of 100 m (325 ft) below the chalk hills. Thus, at the time of its completion, the North Downs Tunnel was both the largest (in terms of CSA) and deepest twin-track railway tunnels to have ever been constructed in the UK. Trains using High Speed 1 can reach 300 kilometres per hour (186 mph) whilst in the tunnel.

Kit's Coty House
Kit's Coty House

Kit's Coty House or Kit's Coty is a chambered long barrow near the village of Aylesford in the southeastern English county of Kent. Constructed circa 4000 BCE, during the Early Neolithic period of British prehistory, today it survives in a ruined state. Archaeologists have established that the monument was built by pastoralist communities shortly after the introduction of agriculture to Britain from continental Europe. Although representing part of an architectural tradition of long barrow building that was widespread across Neolithic Europe, Kit's Coty House belongs to a localised regional variant of barrows produced in the vicinity of the River Medway, now known as the Medway Megaliths. Of these, it lies near to both Little Kit's Coty House and the Coffin Stone on the eastern side of the river. Three further surviving long barrows, Addington Long Barrow, Chestnuts Long Barrow, and Coldrum Long Barrow, are located west of the Medway. They were among the first ancient British remains to be protected by the state, on the advice of General Augustus Pitt-Rivers, the first Inspector of Ancient Monuments. The site is now under the ownership of non-departmental public body English Heritage, and is open to visitors all year round.Kit's Coty can be reached on foot along a track that appears at the junction where the Pilgrim's Way and Rochester Road meet. The chamber is encircled by iron railings. It lies approximately 2 kilometres north of another of the Medway Megaliths, Little Kit's Coty House.The name "Kits Coty" allegedly means "Tomb in the Forest" according to signs at the site, possibly related to the Ancient British *kaitom, later *keiton, meaning "forest". The site is the namesake of Kitscoty, a village in Alberta, Canada. The inclusion of the term "House" in the site's name has confused some visitors, who have gone to the site expecting a built dwelling.

Lower Bell
Lower Bell

The Lower Bell is a pub on the A229 Blue Bell Hill, between Chatham and Maidstone in Kent. It is located at the edge of the North Downs where the A229 meets the Pilgrims' Way.A pub has existed in the general area since around 1790, when the A229 was a turnpike road for coaches. The map maker and artist Paul Sandby painted A Distant View of Maidstone, from Lower Bell Inn, Boxley Hill in 1802, which depicts a view of the town from the pub. It is marked at its current location on a large-scale 1832 map of Kent. The current building was constructed in 1865.The purpose of the bell was for travellers to warn others further up the hill of their presence, as the road was too narrow for two teams of coach and horses to pass each other. There was a corresponding pub at the top of the hill called The Upper Bell, which would ring in response. The Upper Bell was demolished in 2013.The Lower Bell is cited as a location for a common ghost story, which originates from a fatal car accident involving a bride-to-be on the A229 outside the premises in November 1965. The typical story involves the apparition of a young woman attempting to hitch a lift outside the pub into the centre of Maidstone or another local village, who subsequently vanishes en route. A local journalist attempted to verify the story for the Maidstone Gazette in 1968, but was unable to find any suitable eyewitnesses after months of research. In 2015, on the fiftieth anniversary of the accident, a paranormal enthusiasts' group met in the Lower Bell to discuss the various ghost stories. A short film, entitled The Ghost of Blue Bell Hill, was shot around the premises.Live music is a regular feature at the Lower Bell. The pub runs a jam session every Monday.

Medway Megaliths
Medway Megaliths

The Medway Megaliths, sometimes termed the Kentish Megaliths, are a group of Early Neolithic chambered long barrows and other megalithic monuments located in the lower valley of the River Medway in Kent, South-East England. Constructed from local sarsen stone and soil between the 4th and 3rd millennia BCE, they represent the only known prehistoric megalithic group in eastern England and the most south-easterly group in Britain. They remain one of several regionally contained chambered long barrow traditions in Britain, although have certain precise architectural characteristics which mark them out as distinct from other groups. The purpose of these long barrows remains elusive, although some were used as tombs for the remains of a select group of individuals. It is also widely believed that they were places where religious rituals were performed. Many archaeologists believe that they reflect the process of Neolithisation of Britain, as hunter-gatherer populations were replaced by pastoralists. Three chambered tombs have been identified to the west of the river: the Coldrum Stones, Addington Long Barrow, and Chestnuts Long Barrow. To the east of the river, another three chambered tombs have been identified: Kit's Coty House, Little Kit's Coty House, and Smythe's Megalith, although it has also been suggested that two nearby megaliths, the Coffin Stone and the White Horse Stone, are remnants of former chambered tombs. An Early Neolithic longhouse and causewayed enclosure have also been identified in the vicinity of the monuments. The Medway Megaliths have become heavily damaged and dilapidated since original construction, largely due to an intentional program of destruction in the late 13th century CE. They began to attract the interest of antiquarians in the late 16th century, who developed a number of erroneous theories about their origin, before later being scientifically investigated by archaeologists in the late 19th century. Local folklore has also grown up around the monuments, which came to be interpreted and used as sacred sites by contemporary Pagans in the latter 20th century.

Little Kit's Coty House
Little Kit's Coty House

Little Kit's Coty House, also known as Lower Kit's Coty House and the Countless Stones, is a chambered long barrow located near to the village of Aylesford in the southeastern English county of Kent. Constructed circa 4000 BCE, during the Early Neolithic period of British prehistory, today it survives in a ruined state. Archaeologists have established that the monument was built by pastoralist communities shortly after the introduction of agriculture to Britain from continental Europe. Although representing part of an architectural tradition of long barrow building that was widespread across Neolithic Europe, Kit's Coty House belongs to a localised regional variant of barrows produced in the vicinity of the River Medway, now known as the Medway Megaliths. Of these, it lies near to both Kit's Coty House and the Coffin Stone on the eastern side of the river. Three further surviving long barrows, Addington Long Barrow, Chestnuts Long Barrow, and Coldrum Long Barrow, are located west of the Medway. Now a jumble of half-buried sarsen stones it is thought to have been a tomb similar to that of the Coldrum Stones. The name is derived from the belief that the chaotic pile of stones from the collapsed tomb were uncountable and various stories are told about the fate of those who tried. Another nearby site that may have been Neolithic is at Cossington. There are between 19 and 21 stones depending on the authority. They were pushed over in the seventeenth century seemingly before any antiquarian interest was taken in them. William Stukeley attempted to reconstruct the damaged tomb in plan in the eighteenth century. Archaeological evaluation trenching in 1989 found no clear evidence of any surrounding quarry ditch which would normally have been excavated to provide material for a covering barrow.

Coffin Stone
Coffin Stone

The Coffin Stone, also known as the Coffin and the Table Stone, is a large sarsen stone at the foot of Blue Bell Hill near Aylesford in the south-eastern English county of Kent. Now lying horizontally, the stone probably once stood upright nearby. Various archaeologists have argued that the stone was part of a now-destroyed chambered long barrow constructed in the fourth millennium BCE, during Britain's Early Neolithic period. If a chambered long barrow did indeed previously exist on the site, it would have been built by pastoralist communities shortly after the introduction of agriculture to Britain from continental Europe. Long-barrow building was an architectural tradition widespread across Neolithic Europe. It consisted of various localized regional variants; one of these was in the vicinity of the River Medway, examples of which are now known as the Medway Megaliths. The Coffin Stone lies on the eastern side of the river, not far from the chambered long barrows of Little Kit's Coty House, Kit's Coty House, and the (now destroyed) Smythe's Megalith. Three other examples, the Coldrum Long Barrow, Addington Long Barrow, and Chestnuts Long Barrow, remain on the western side of the river. The Coffin Stone is a rectangular slab lying flat that measures 4.42 metres (14 ft 6 in) in length, 2.59 metres (8 ft 6 in) in breadth, and about 0.61 metres (2 ft) in width. Two smaller stones lie nearby and another large slab is now located atop it. In the 1830s it was reported that local farmers found human bones near the stone. An archaeological excavation of the site led by Paul Garwood took place in 2008–09; it found that the megalith was placed in its present location only in the 15th or 16th centuries. The archaeologists found no evidence of a chambered long barrow at the location, and suggested that the Coffin Stone might once have stood upright in the vicinity.

Bluebell Hill transmitting station
Bluebell Hill transmitting station

The Bluebell Hill transmitting station is a broadcasting and telecommunications facility located at Blue Bell Hill between Maidstone and Rochester in the English county of Kent. The station is situated on the crest of the North Downs and comprises five steel lattice towers, each 45 to 50 metres tall - their height being compromised by the location of nearby Rochester Airport. It broadcasts digital television, FM and DAB radio to much of north, west, and central Kent, and an overspill service into southern Essex. It stopped broadcasting analogue television when the digital switchover was completed on 27 June 2012. When in analogue service, the broadcast power of 30 kW for a main transmitter was unique in the United Kingdom, the strength being limited by potential interference with transmitters in France and the Low Countries. Services broadcast include BBC One (South East), BBC Two, ITV1 (Meridian), Channel 4, Heart Kent, KMFM Medway and KMFM Maidstone. Between its opening in 1974 and 31 December 1981 the transmitter broadcast Thames Television (weekdays) and London Weekend Television (weekends), being switched on 1 January 1982 to carry signals from the new ITV franchise TVS (Television South), until superseded on 1 January 1993 by ITV Meridian for ITV in the south east. The transmitter takes its main BBC1 feed from Crystal Palace, with an opt-out for BBC local broadcasting in the South East relayed from studios in Tunbridge Wells. Although timing is of the essence at this point the human factor sometimes results in a delay of a second or two, enabling viewers to glimpse the London studio and presenter before the Tunbridge Wells studio appears. On occasion the local news is combined with the London or South region, usually through staff shortages at one studio or other. This amalgamated programme is usually broadcast from the Tunbridge Wells studio. Bluebell Hill was originally an E group for analogue, then became a B group at DSO. At its 700 MHz clearance in July 2018 it became a K group (excluding the temporary MUXES 7 and 8). Most E groups and B groups, as well as widebands and K groups, will work satisfactorily on Bluebell Hill (see graph).
