Once known for lace-making, tourism, and being the closest French port to England, Calais has now come to represent a focal point of illegal immigration.
Hundreds of migrants roam the town by day. At night they sleep in squalid tent cities, their clothing hanging on fences and from the trees. The migrants have fled war, poverty and dictatorship, in places like Eritrea, Afghanistan and Sudan. They've traveled over desert and sea, on journeys that often take years.
Now, they're trying to get the last 30 miles to England.
