Western Heights in Dover represents one of Britain's most important fortification systems, begun during the Napoleonic Wars and completed in the 1860s. This vast network of linked forts, redoubts, and miles of ditches was designed to protect Dover from French invasion. The North Centre Bastion and the Drop Redoubt, now maintained by English Heritage, showcase the scale and sophistication of 19th-century military engineering. Following abandonment by the Army between 1954 and 1961, Western Heights has been designated as a local nature reserve, with its chalk grassland supporting important protected species and wildlife habitats.
