Durham today

A county of half a million and a city of students

Census 2021 figures from the Office for National Statistics on Nomis, for the County Durham unitary authority and for four middle-layer areas around the city, named by the House of Commons Library.

County Durham and Durham city areas, Census 2021
Area	Usual residents	Students among those aged 5 and over	Residents per square kilometre
County Durham	522,068	19.9%	234.5
Durham City	12,666	79.9%	1,787.9
Gilesgate and Old Durham	6,746	35.6%	2,086.8
Aykley Heads, Neville's Cross and Langley Moor	13,300	40.1%	1,052.6
Pity Me and Framwellgate Moor	6,194	20.0%	2,439.6
England	56,490,048	20.4%	433.5

Colleges on the map

In the Durham City area, 6,315 of the 12,666 residents lived in communal establishments such as college accommodation, and 42.2% were aged 20 to 24.

A spread-out county

County Durham as a whole had 234.5 residents per square kilometre, well under England's 433.5, with 508,762 people living in households.

Close to the national mix

Across the county, 19.9% of residents aged five and over were in study, near England's 20.4%; the city centre is the exception, not the rule.

Our Durham learners reflect that range. A Year 3 child in Newton Hall might be making a first animation, a Year 10 student in Gilesgate choosing GCSE Computer Science projects, and an adult in Framwellgate Moor learning Python for work, each in a small group at the right level.

The peninsula

A tower rebuilt after lightning, and a battle watched from the top

From the Durham World Heritage Site's own pages and Historic England's open listing data.

1346

Medieval sources, the World Heritage Site says, record that the monks watched the Battle of Neville's Cross from the top of the central tower and began to sing when they saw the Scots defeated.

1429 and after

The central tower was struck by lightning and repaired in 1429, then struck again thirty years later. A new tower was built between 1465 and 1474, and a second storey followed ten years later.

1986

UNESCO inscribed Durham Castle and Cathedral on the World Heritage List. Historic England lists the Cathedral at Grade I, and records a registered battlefield for 1346 on the city's western edge.

The dates matter for our project. The tower visitors climb today was built more than a century after the battle, so the tower the monks stood on in 1346 was an earlier one, and we could not find its height in any source we were able to check. That is why the project asks how high an eye would need to be, rather than pretending to know. The site also recalls that, for many years afterwards, monks climbed the tower on 17 October to sing to the north, south and east, with St Cuthbert's shrine still at the heart of the cathedral below.

Where the heights come from

Ordnance Survey Terrain 50 is a free grid of ground heights across Great Britain, one value for every 50 metre square. It shows bare ground, with no buildings or trees, which suits a question about 1346 better than a modern surface would, though it smooths the steep banks of the peninsula.

Signature project

Could the monks have seen the Battle of Neville's Cross?

Bresenham's algorithm picks the grid cells a straight line passes through using only whole-number steps. Line of sight then asks whether any cell along the way rises above the line from eye to target.

Registered battlefield of Neville's Cross, 157 cells of Terrain 50, seen from the Cathedral's listed position; target a person 1.7 metres tall
Eye height above the cathedral's ground	Cells in view	Share
0 to 30 metres	0	0%
40 metres	3	2%
50 metres	4	3%
60 metres	16	10%
70 metres	37	24%
Any height up to 300 metres	143	91%

1. Draw the line

From the cathedral cell to the monument cell, Bresenham visits 23 squares, updating a running error term with whole-number additions and never touching a fraction. The heights dip to 29.9 metres where the line crosses the Wear.

2. Test the slope

Work out the angle from the eye to the target, then check each square in between. If any square's angle is steeper, the target is hidden. At 1,110 metres, the curve of the Earth changes heights by only 0.08 metres.

3. Find the height

Visibility only improves as the eye rises, so bisection can find the lowest eye that works: 10.4 metres for the monument, from 32.2 metres to well over 85.2 metres for the battlefield squares.

A story the terrain neither proves nor rules out

The monument itself is easy to see, but the registered battlefield lies beyond rising ground as seen from the cathedral, and even from 70 metres most of it stays hidden. That does not mean the chroniclers were wrong. Fighting moves, the registered boundary is a modern judgement, and a person 1.7 metres tall is only one choice of target. What the model does show is exactly which assumptions the story depends on, and that is the most useful thing a model can do.

We checked the method as well as the answer. Sampling each line every 5 metres with smoothly interpolated heights, instead of Bresenham's whole squares, gave the same verdict for all 157 battlefield cells at 20 and 40 metres. Widening the question to a full viewshed, every square within 5 kilometres, shows the cost of the simple approach: 1,854,044 square visits for one eye height, with 6.3% of the area in view from the ground, 40.4% from 40 metres and 65.1% from 70 metres.

Line of sight in practice

Five checks before trusting a visibility map

Practised on Neville's Cross, then used for phone masts, wind farm planning, security cameras, games and flight paths.

Decisions behind any line of sight answer
Check	For the 1346 question	If it is skipped
What surface?	Bare ground, no buildings or trees	A modern town hiding a medieval view
How fine a grid?	50 metre squares, steep banks smoothed	Cliffs turned into slopes without warning
Where exactly is the eye?	The listed point, at stated heights	One precise answer from an unknown height
What counts as seen?	A person 1.7 metres tall	Ground level targets, which hide far more easily
Does the method agree with another?	Bresenham against 5 metre sampling	A grid artefact reported as history

The third row changes everything. Report one height and the page would announce either that the monks saw the battle or that they could not, and both would sound certain. Reporting the answer across a range of heights, and saying plainly that the 1346 tower's height is unknown, is less dramatic and much more honest.

Younger learners

Drawing lines on squared paper square by square, then standing toy figures behind blocks to see who can spot whom.

Teenagers

Bresenham in Python, a height grid from Ordnance Survey, a line of sight test, bisection for the lowest eye, and a second method to check the first.

Adults

Visibility and terrain questions at work, with the surface, grid size and assumptions written down beside every map.

We are not connected with Durham Cathedral, Durham University, the Durham World Heritage Site, Historic England, Ordnance Survey or Durham County Council. The height grid, listing records and census tables are open data; the lines, heights and viewsheds on this page are our own calculations.

Coding and AI

AI can draw a map in seconds. Why should a Durham teenager trace a line through one?

Because the useful question is not what the answer is, but what it depends on.

Ask an AI tool whether the monks could see the battle and it will probably give a confident yes or no. A learner who has traced the line square by square knows the answer depends on the tower's height, the grid, the surface and what counts as seen, and can ask the tool the questions that expose a guess.

Bresenham's algorithm is also a reminder that fast, simple code still runs everywhere. It was designed for drawing lines with whole numbers, and the same idea of stepping through a grid sits behind graphics, games and robot navigation. Building it by hand makes the grid underneath modern tools visible.

So a Durham teenager should keep learning to code in 2026, within sight of a tower rebuilt after lightning: machines will answer quickly, but someone has to know which assumptions the answer is standing on. The longer argument is in why coding is worth learning in 2026.

Delivery

Gilesgate, Belmont or Brandon, and never a trip to the peninsula

The city spreads from the colleges by the river to the estates and villages on the hills around it. Online, every one of them is next door to the lesson.

Hills and river

A learner in Sherburn and another in Ushaw Moor can share one class without crossing the Wear or finding a bus into town.

English school stages

We teach to the stages used in County Durham schools, Reception and Key Stages 1 to 4 through to GCSE and A level, entirely in English.

A lesson with substance

The free session works through a real task and closes with a recommended level, course and weekly slot. We do not ask for card details.

Stage, not postcode

Groups hold five to ten learners at the same stage, from Durham, the rest of the UK and overseas, so every level has sensible times.

Two lessons a week

Two regular lessons each week, around eight a month, with half terms and exam seasons planned with the teacher in advance.

An evening here, late there

A 4.30 pm lesson in Durham starts at 9 pm in India while the UK is on summer time and at 10 pm in winter, because India keeps one time zone all year; our teachers work their evenings around UK families.

Across the North East

Families in Chester-le-Street, Spennymoor, Bishop Auckland or Consett join the same live groups, since every class is online and arranged by level.

Fees

Durham lesson fees

The first lesson is free; after that there is one monthly fee.

First classUSD 0

A full lesson with nothing to pay, ending with advice on level, course and a weekly slot.

Group tuitionUSD 100

Roughly eight live lessons a month, in a group of five to ten learners at one stage.

Private tuitionUSD 150

Roughly eight live lessons a month, with the teacher working with your learner alone.

Whether you live in Newton Hall or Neville's Cross, the fee is set in US dollars, as it is for every family outside India, and the site shows no pound prices. Nothing is billed until after the free lesson, when the course and weekly slot are agreed; pauses, missed lessons and changing between group and private teaching are all set out on the pricing page.

FAQ

Durham coding class questions

The questions we hear most often from Durham families.

How many people live in County Durham?

The 2021 census counted 522,068 usual residents in the County Durham unitary authority, 508,762 of them in households. The middle-layer area the House of Commons Library names Durham City had 12,666.

Why is the Durham City area so different from the county?

It is where many students live: 10,073 of its 12,608 residents aged five and over were studying in 2021 (79.9%, against 19.9% for the county), and 6,315 residents lived in communal establishments such as college accommodation.

What is Bresenham's line algorithm?

A method published by Jack Bresenham in 1965 for choosing which grid squares a straight line passes through using only whole-number addition and comparison. It was designed to control a digital plotter, later drew lines on screens, and is used here to walk across a grid of heights.

Could the monks see the Battle of Neville's Cross?

It depends on assumptions. On Ordnance Survey Terrain 50, a person at the Neville's Cross monument is visible from 10.4 metres above the cathedral's ground, but most of the registered battlefield needs an eye far higher, and the height of the 1346 tower is unknown.

Where do the heights and battlefield come from?

The heights are Ordnance Survey Terrain 50, free open data on a 50 metre grid. The Cathedral's position, the monument and the registered battlefield boundary come from Historic England's open listing data.

What happened to the cathedral's central tower?

The Durham World Heritage Site says it was struck by lightning and repaired in 1429, struck again thirty years later, and rebuilt between 1465 and 1474, with a second storey added ten years later. We are not connected with the Cathedral or the World Heritage Site.

What times do Durham lessons run?

Durham families usually go for a slot after school, a weekday evening or a weekend morning, and we agree the time in the free lesson. India runs four and a half hours ahead of the UK in summer and five and a half in winter.

Do you have a centre in Durham?

No. We have no Durham centre and no premises anywhere in the UK, because every lesson is live online. Learners need a computer with sound and a stable connection, and the number you will call is Indian.

How much are lessons for a Durham learner?

The first lesson is free. Then a group place is USD 100 a month for two live lessons a week, about eight a month, with five to ten learners; one-to-one lessons on the same timetable are USD 150 a month. The course, format and time are agreed before anything is charged.

How do you decide which group a learner joins?

By level, pace and aims rather than age or address, so each group has five to ten learners at one stage. If no group fits the learner's timetable, one-to-one lessons are available instead.
