A number of Palmerston Forts were built along the south coast of England on recommendation of the 1860 Royal Commission on the Defence of the United Kingdom. As well as new structure, many existing defences were improved. Most were clustered around major ports, such as:
Dover Isle of Wight Plymouth Portland Harbour Portsmouth
However, some more isolated works did take place at:
Hurst Castle, Hampshire Littlehampton Redoubt, Littlehampton, West Sussex Newhaven Fort, Newhaven Shoreham Redoubt, Shoreham-by-Sea, West Sussex
