A few miles inland from Lesbos' main town is a place the authorities would rather you didn't see.

Moria looks like a barbed wired fortress. It was built four years ago with European Union money.

It was supposed to be a central part of the solution to the continent's migration crisis; a migrant camp, an efficient processing centre with room for 2,000 people.

The latest figures from the Greek migration ministry, from the weekend, put the population at 6,123.

It is run by the Greek government and paid for by the European Union.

Our access is around the back and through one of many holes in the fence.

Inside, it's clear quickly that this isn't a place just full of young men, chancing it in Europe. It is full of families.

It is the playground for hundreds of children. Many walk around alone or in couples. They wander among the rubbish and their own faeces, which are everywhere.

The charities are here: Medecins Sans Frontieres, The Samaritans, the UNHCR and more. But they are totally overwhelmed.

Our guide through the warren is Abraham. He fled Iraq, he says, after he was persecuted for converting to Christianity.

"In the Middle East - Iraq, Syria - there is no life. Dangerous," he says.

You don't have to seek the stories out here. They come to you. We meet Hamoud from Syria. He takes us to his tent because he wants to show us his daughter.

"She is very sick. Can you see her?" he says.

We don't know what's wrong with her because he doesn't either. She looks ok, which is encouraging.

Hamoud's Syrian ID card shows the family is from the town of Raqqa, the headquarters of the Islamic State - until the place was flattened two months ago.
