centre of great britain, centre of united kingdom

If uou click on this map of the United Kingdom, you can see two small pink circles which, very roughly, mark the centre of Great Britain (including its 401 islands) and the centre of England.

If someone asked you where the centre of Great Britain was or for that matter where the centre of England was, would you know? Or more to the point would you care? The centre of Britain must obviously be further north than the centre of England, as Britain includes Scotland, of which there is quite a lot. And the centre of Britain is likely to be further west than the centre of England because of Wales.

Northern Ireland is not included in the centre of Great Britain as the country we are part of is the United Kingdom of Great Britain and Northern Ireland, that is Great Britain doesn’t include  Northern Ireland. Well to add to the other obscure geographical posts that I have written previously, here are some answers.

The nearest village to the geographical centre of Britain (including its 401 islands) was officially recognised by the Ordnance Survey in 1992 as being Dunsop Bridge in the Forest of Bowland near Clitheroe in Lancashire. However in 2002, the Ordnance Survey calculated that the exact point is at Whitendale Hanging Stones (grid reference SD 64188 56541), near Brennand Farm, 4½ miles north of Dunsop Bridge. The measurement calculates the point at which a two-dimensional object – think of a cardboard cut-out of Great Britain – would balance horizontally on the head of a theoretical pin, that is its centre of gravity.

BT also installed its 100,000th payphone at Dunsop Bridge (not by coincidence surely?) and included a plaque to explain its significance. The plaque reads ‘You are calling from the BT payphone that marks the centre of Great Britain.’ The telephone box was unveiled by the explorer and writer Sir Ranulph Fiennes.

The geographical centre of England was calculated by the Ordnance Survey in 2002, again by finding the centre point of the two-dimensional shape made by England. It is in a field close to Lindley Hall Farm near Fenny Drayton in Leicestershire (grid reference SP 36373 96143).

A post next to a hedge in a field of Lindley Hall Farm near Fenny Drayton points to the exact centre of England.

In June 2013, a 6ft high ‘monument’ made from a railway sleeper was erected on the side of the field with a sign pointing to the exact point, 492ft into the field. According to a BBC report at the time, the owner of the farm, Stephen Farmer, said it could become a tourist attraction in future, explaining that ‘It’s a position on the map, the same as Land’s End [and] John O’Groats. People go to see their marks and have their photos taken so I think it wants to be known to the public, where it is.’ As the field and the path to it are privately owned, Mr Farmer will presumably have to allow public access to the monument if he wants to put it on the map. Incidentally Dunsop Bridge is roughly 95 miles north-north-west of Fenny Drayton.

Some people argue that the furthest point from the sea should be considered the centre of Britain. The Ordnance Survey has found this point is just east of Church Flatts Farm, about a mile south-east of Coton-in-the-Elms, Derbyshire. Haltwhistle in Northumberland also claims, less convincingly, to be the centre of Britain based around it being on the mid-point of the longest line of longitude (the vertical line) on the mainland of Britain. The town even has a Centre of Britain Hotel!

How do you decide what is the most featureless place? The Cambridge dictionary defines featureless as ‘looking the same in every part, usually in a way that most people consider to be boring’. Even the wildest parts of Scotland or the flattest fen in East Anglia have a ditch, bridleway, stream or hill to break the monotony.

Over ten years ago a listener to John Peel’s Home Truths show on Radio 4 asked about boring places in Britain. This triggered the search for Britain’s most boring place. The BBC turned to the Ordnance Survey to see if looking at maps would provide the answer on the basis that their large-scale maps show almost all features in the landscape. Maps are divided by grid lines into squares that are a kilometre wide and tall, and features are identified by various symbols. The obvious thing to do therefore was to find the grid square that had the least symbols in it. Was there a completely blank square among the 320,000 squares in the widely-used Landranger map series? This series of maps are at a scale of 1:50,000, that is one centimetre on the map is 50,000 centimetres on the ground, which is half a kilometre.

After setting a computer to look at every one of the squares, the Ordnance Survey came up with answer! A field in the East Riding of Yorkshire is the most featureless place in Britain.

The square kilometre of farmland on the outskirts of the village of Ousefleet, just south of the River Ouse, near Scunthorpe, has nothing in it except a single electricity pylon and some overhanging cable. The square at grid reference SE 830 220 (the south-west corner of the square) on OS map 112 is as near as cartographers can get to a completely blank square in the Landranger map series.

Philip Round from the OS said at the time ‘We’re not saying it’s the dullest place in Britain. It might be the most fascinating place on earth but on our Landranger maps it has the least amount of information. No ditches, streams or buildings are shown on this particular scale of map. That’s quite some going, considering the low-lying areas of East Anglia and remote parts of Scotland.’

What is the furthest point from a tarmaced public road in mainland Britain? There may be other contenders for remoteness, but the Ordnance Survey has determined this point as a peat bog on the western hillside of Ruadh Stac Beag in Wester Ross in Scotland, amongst the burns (‘allt’ in Gaelic) that come from Lochan a Bhraghad. The point is at a height of about 610m (2,000 feet) and the grid reference is NH 0202 7700.

It is 10.43 km (6.48 miles) in a straight line from the nearest road, the A832 near the village of Kinlochewe. But up here in the boggy  mountainous wilderness of the Fisherfield Forest of Wester Ross, that doesn’t mean very much.

The shortest distance by a path, where there is one, is from Kinlochewe, the nearest settlement, and it is 24.2 km (15 miles). There are a number of deer-season only hunting lodges and abandoned houses, and an out of season bothy, Shenavall, to the north of the ‘furthest point’ near Loch na Sealga and below An Teallach (1,062m), but that is all. There is a nearer settlement at Letterewe on the side of Loch Maree to the south-east, but that is on a private estate.

There are no photographs of the location as far as I know but the nearest photograph, below right, is of Lochan a’ Bhraghad, a small lochan close by. For what it’s worth, the ‘furthest point’ is about 500m away over the slight hill on the right side of the picture.

In 2002, the Daily Telegraph sent one of its reporters, Colin Cottell, to this remote spot. He rang the Ordnance Survey to check before setting out. ‘Less than seven miles? Hardly worth getting out of my sleeping bag for. Or so I imagined’. His report is here.

The Fisherfield Forest, and the Dundonnell Forest to the north, is sometimes nicknamed The Great Wilderness because the area is entirely devoid of permanent settlements. Although termed a forest, the area has very few trees, though it was a pine forest 200 years ago.

Three estates cover most of the area which is maintained primarily for deer stalking: Dundonnell Estate covers 134 km² in the northwest part of the forest, the Eilean Darach estate covers 262 km² in the northeast, and majority of the area, including all the southern and central sections, forms the 323 km² Letterewe estate.

ScottishMilitarySurvey

Extract of Map from the Scottish Military Survey 1747-1755

What’s the difference? Other than an ‘i’.

Ordinance is a law, or rule and regulations, made by a government or municipal authority eg. ‘The draft ordinance is currently under debate’.

Ordnance refers to military supplies, especially weapons and bombs, or to large guns on wheels eg. ‘Do not touch any military ordnance that may be found lying around this area’. The most familiar use is in Ordnance Survey, the national mapping agency for Great Britain, which publishes large and small-scale maps, and which was formed in 1791. The name reflects the original military purpose of the archetype organisation which was the mapping of Scotland in the aftermath of the last Jacobite Rebellion, and the Battle of Culloden in 1746.
