Swanscombe is a village in the Borough of Dartford in Kent, England, and the civil parish of Swanscombe and Greenhithe. It is 4.4 miles west of Gravesend and 4.8 miles east of Dartford.

Bone fragments and tools, representing the earliest humans known to have lived in England, have been found from 1935 onwards at the Barnfield Pit about 2 km (1 mile) outside the village. This site is now the Swanscombe Heritage Park. Swanscombe Man (now thought to be female) was a late Homo erectus or an early Archaic Homo sapiens.[2] According to the Natural History Museum, however, the remains are those of a 400,000-year-old early Neanderthal woman.

The c. 400,000-year-old skull fragments are kept at the Natural History Museum in London with a replica on display at the Dartford Museum. Lower levels of the Barnfield Pit yielded evidence of an even earlier, more primitive, human, dubbed Clactonian Man.

Nearby digs on land for the Channel Tunnel Rail Link revealed a c. 400,000-year-old site with human tools and the remains of a Straight-tusked Elephant (Palaeoloxodon antiquus), and evidence of water vole, pine vole, newts, frogs etc., indicating a site with standing water similar to a swamp.

During archaeological work undertaken at Ebbsfleet, before construction of High Speed 1, an Anglo-Saxon mill and a Roman villa were found near Swanscombe.

From Crayford to the Isle of Thanet the Danes occupied the land and terrorised the Saxon inhabitants, giving rise to the appearance of Deneholes, of which many have survived to this day. These were wells, cut deep into the chalk landscape, thought to be for concealing people and goods. They have a simple vertical shaft with short tunnels bearing horizontally from the base.

The Vikings settled throughout the winter along the Thames estuary with their ships and established camps in Kent and Essex. In surveying the distribution of the many deneholes along the Thames corridor it would appear that Essex, on the northern shore of the Thames, sustained a greater influx of Vikings than did Kent, there being considerably more recorded deneholes in Essex, particularly around Orsett and Grays.

Archaeological digs and centuries of tilling have revealed a Danish castle and settlement, with pottery, anchors, weapons and some ships' timbers. The settlement was later variously called Suinescamp (in the Domesday Book of 1086), Sweinscamp and Swanscamp. Legend derives the name from the Viking king Sweyn Forkbeard, who landed in East Anglia and became King of England in 1013. The father of Canute, Sweyn died at Gainsborough, on the Trent, in 1014. Canute (Cnut) died in Shaftesbury in 1035, and his sons were unable to hold on to his empire. But the name of Swanscombe cannot derive from Sweyn Forkbeard, as the place-name is first attested in 695 AD.

Other research suggests that deneholes might have been dug as a method of extracting chalk for use on the fields above, or the mining may have been a by-product of defence. In any case the practice reached a peak around the 13th - 14th centuries, long after the Viking raids had ceased.

It is claimed, apparently without evidence, that in 1066 Swanscombe locals massed an army in defiance of William I and so won the right to continue their ancient privileges, including the tradition of passing inheritance by gavelkind. The men of Kent met William near Swanscombe, where the Saxons concealed their number with branches, thus intimidating the Norman army. Again according to legend, they were offered a truce that left Kent as the only region in England that William left unconquered. Hence in this area of England alone, Kent County Council adopted the motto Invicta, meaning unconquered.

Richard Norman Shaw designed All Saints' Church in 1894, built out of knapped flint for the workers of the cement industry. It survives as a rare example of his design, covering several Gothic Revival styles throughout its architecture and features, such as Decorated tracery on the windows and Arts and Crafts Perpendicular woodwork in the interior.

The flint parish church of St Peter and St Paul is mostly of the 13th century. However various sections contain Early Norman material. The tower and chancel contain 11th and 12th-century work respectively, although the tower was reconstructed in the 13th century and the chancel arch is from the 14th century. The lower section of the tower contains some Saxon material. The tower is topped with a broached shingled spire, and in 1902 the church was struck by lightning causing extensive damage. A large-scale restoration was undertaken by Jabez Bignall in 1872-73 and again by him after the damage from the lightning strike. The parish register dates from 1559. George Cecil Renouard is buried in the Swanscombe churchyard.

Just after 8 o'clock in the evening of Sunday 10 November 1940 a German bomb crashed down direct into The Morning Star Inn, causing in a single explosion Swanscombe's worst wartime disaster. All that was left after the explosion was, where the pub had stood, a "heap of bricks and twisted rafters" surrounding the smouldering pit that had been the cellar, although the staircase leading to the clubroom upstairs extended up out of the wreckage. Distressed families of those known to be in the pub at the time gathered at the street corners awaiting news of the casualties as bodies were gradually recovered from the ruins.

The official casualty lists revealed the death toll to be 27, with six others seriously injured and five people slightly hurt.

"The landlord was amongst the dead, although his wife and son survived. The barmaid who was killed had given notice the week before the raid but had stayed on that evening because of the match. One of the other victims was a merchant seaman on seven days' leave who had spent two days travelling from Scotland to see his wife and children and was having a drink with his father in the pub at the time of the bombing: both were killed."

On 30 July 1940 another Luftwaffe raid led to the death of more than a dozen civilians, with 22 seriously injured. Its proximity to London and position under the German flight path to the city meant that Swanscombe fell victim to this kind of damage several times during the war.

On 30 July 1944 a V1 rocket landed on Taunton Road. Half of one side of the road was wiped out. 13 were killed and 22 seriously injured.

Ebbsfleet International railway station (IATA: XQE) is in Ebbsfleet Valley, Kent, 10 miles (16 kilometres) east of London, England, near Dartford and the Bluewater shopping centre to the west and Gravesend to the east. The station, part of the Thames Gateway urban regeneration project, is on the High Speed 1 rail line, 400 metres (440 yards) south-west of Northfleet railway station, off the A2 trunk road, 5 mi (8 km) from its junction with the M25 motorway. It served as a primary park-and-rail service for the London 2012 Olympics.

Ebbsfleet International is owned by HS1 Ltd, which operates the High Speed 1 railway and St Pancras railway station, Stratford International, Ebbsfleet International and Ashford International.

The name Ebbsfleet dates from the seventeenth-century. The station is partly inspired by the name of Ebbsfleet in Thanet, 75 km (47 mi) to the east.
