World War II bombing decoy HA2 Kirby-le-Soken

Tucked away in farmland between Kirby-le-Soken and Walton on the Naze lies one of Britain's most unusual wartime relics - a concrete structure that once fooled German bombers into thinking they'd found Harwich port. This Second World War decoy site, known as HA2, was part of a clever deception operation designed to draw enemy aircraft away from the real naval installations.

What you'll find today is a collection of concrete foundations and earthworks, remnants of fake buildings and infrastructure that once mimicked the genuine port facilities. History enthusiasts will appreciate the ingenuity behind these elaborate ruses, though don't expect much in the way of interpretation boards or formal facilities.

Access appears to be via public footpaths across working farmland, so proper walking boots are essential. The site works well as part of a longer walk exploring this quiet corner of Essex, perhaps combined with a trip to nearby Walton on the Naze.

Families staying at Parkdean's Naze Marine or other local holiday parks might find this a bit niche for younger children, but older kids with an interest in military history could find it fascinating. Allow an hour to explore properly, and check locally about access permissions before setting off.
