Work has started on Europe's largest man-made nature reserve, which will eventually be home to tens of thousands of migratory wetland birds.
It's being created using the millions of tonnes of earth from dug out for London's Crossrail project, which will allow rail passengers to journey between Shenfield in Essex, across the capital to Maidenhead in Berkshire.
The project will see Wallasea Island, near Southend, transformed into a massive wetland habitat.
