The War Office had some inspirational (and fanciful) ideas when it came to camouflaging pillboxes to fool German pilots during World War Two.
According to Lewes At War (Alma Cott) by R A Elliston, one by the Brooks was built to look like a railway signal box.
At the Pells another was disguised as a cafe with toilets.
Another at Swanborough looked like a roadside tea room with a verandah.
The Rise Farm example (pictured) was, amazingly, designed to look like a haystack.
Lewes Prison had two pillboxes, one at the main entrance sited to fire down Western Road with the outside painted to match the knapped flint boundary wall.
The other covered Spital Road. Clever stuff.
