The London Defence Positions were a late 19th century scheme of earthwork fortifications in the south-east of England, designed to protect London from foreign invasion landing on the south coast. The positions were a carefully surveyed contingency plan for a line of entrenchments, which could be quickly excavated in a time of emergency.
