As part of Aylsham’s wartime defences, several pillboxes and guard posts were built at strategic points around the town. Two were located at this important entry point – one here on the main Norwich Road and another opposite on Buxton Road overlooking the train station on the London & Great Eastern railway line. Today only this one remains visible.

These small fortified concrete structures were used as defensive strong points during the threat of invasion. Designed to accommodate machine guns and other weapons, they featured narrow slits, or loopholes, allowing the Home Guard to fire while remaining protected inside.

Aylsham lay just behind the FII demolition belt – a defensive line where local bridges spanning the River Bure, including Millgate Bridge, were rigged for demolition by the Royal Engineers in the event of an invasion.
