The Great Wall of........Europe
The amazingly extensive complex of defensive walls, forts, castles and ditches built by the Roman Empire to mark and defend its northern limits across Europe will soon capture the attention of UNESCO, the United Nations cultural organization, in a bid to be officially crowned World Heritage status, alongside such sites as the Great Wall of China. Researchers from the UK and Germany have united to develop and submit the proposal. They plan to accomplish their goal in two stages -- the first to include Hadrian's Wall in the UK and 300 miles of forts, embankments and ditches in Germany -- and the second to include the entire line of defensive features across Europe to the Black Sea. It's about time, I say.
