Northumberland, England, 2006
The Emperor Hadrian ordered the construction of the wall which now bears his name, in recognition that the Roman Empire did not have the resources to occupy the whole of Britain. The wall spans the width of the island, from the Solway to the Tyne, and was garrisoned by soldiers from many parts of the empire. Unfortunately, there are no surviving accounts of what the Iraqi troops stationed here thought of the unruly and uncivilised Britons.
This section of the wall was built to use the commanding heights of the Whin Sill, an escarpment of hard igneous rock which formed about 295 million years ago, at the end of the Carboniferous period.
