Anti-Tank Defences

As part of the anti-invasion defences in WW2 various means of stopping or delaying motorized units were adopted. One device was Dragon's Teeth. These were truncated concrete pyramids designed to stop a tank from crossing and were arranged in rows giving the appearance of teeth, hence the name. Another method used on the chalk Downs around Folkestone were the Tank Traps. These were an almost continuous ditch with a flat bottom and vertical back cut into the hillside about half way up and ran for miles around the hills behind Folkestone. Now the sharp edges have collapsed, but originally the white scar in the green hills could be seen for miles.
