| How do we decide what's worth saving and what we would happily see destroyed to make way for development? For The Editors, a programme which sets out to ask challenging questions, I asked what price, for example, for the White Cliffs of Dover? | How do we decide what's worth saving and what we would happily see destroyed to make way for development?

| Woven into the national fabric as a symbol of wartime defiance, the cliffs stand immortalised by the voice of Vera Lynn and images of soaring Spitfires. | Woven into the national fabric as a symbol of wartime defiance, the cliffs stand immortalised by the voice of Vera Lynn and images of soaring Spitfires. |

| Most people would probably agree that that was a good thing. The trust's campaign video flashed up names such as Caesar and Churchill to emphasise the pivotal importance of the cliffs to our island story, and the donations rolled in. | Most people would probably agree that that was a good thing.

| What makes the cliffs so distinctively white is that they are made of limestone. As it happens, this type of rock isn't particularly valued. You can buy a tonne of it for about £20. | What makes the cliffs so distinctively white is that they are made of limestone. As it happens, this type of rock isn't particularly valued.

| But what if another kind of mineral was discovered inside the cliffs? Let's say, purely hypothetically, that the cliffs contain gold. | But what if another kind of mineral was discovered inside the cliffs? Let's say, purely hypothetically, that the cliffs contain gold. |
| Now imagine that gleaming deposit of gold is valued at £10m. Would you agree to it being gouged out of the rock? Of course not.

| But what if the gold was worth £1bn? At that price a few people might agree to let the diggers move in. After all, a new mine would create jobs and the Treasury would get another, very welcome, source of revenue. So would the National Trust. | But what if the gold was worth £1bn?

| There would be a protest movement, obviously, and I'm guessing that the majority would be outraged at the idea of sacrificing the cliffs for a mere billion. However, we would start to see a fracturing of public opinion, wouldn't we? | There would be a protest movement, obviously, and I'm guessing that the majority would be outraged at the idea of sacrificing the cliffs for a mere billion.

| Or would you stiffen your spine, summon up the memory of Winston's call to fight invaders on the beaches and draw a principled line in the chalk? Some things, you could say, are just too precious. If the White Cliffs, why not Stonehenge?

| A third point is that priorities change. When the Normans landed and conquered Britain in 1066, they built a massive castle on top of the White Cliffs.

| When Napoleon massed his armies on the other side of the Channel, a huge fortress was built above Dover at the Western Heights.
