Yardley Chase

Yardley Chase is a protected natural site spanning woodland, pasture, and parkland across the Northamptonshire and Buckinghamshire border. The landscape contains concrete bunkers built during World War II that remain embedded in the ground.

The site evolved from a Norman hunting ground into a military facility when underground bunkers for ammunition storage were constructed in 1942. This transformation left a lasting mark on the landscape, layering medieval and modern history.

The oak woodlands here contain a tree that inspired poet William Cowper to write his reflective poem Yardley Oak. This tree remains central to the place's connection with English Romantic literature.

The site is generally not open to the public as it operates as a training facility for cadets. Those interested in exploring the historical and natural features can use surrounding public paths to walk around the perimeter.

The site hosts around 30 breeding butterfly species, which thrived here thanks to minimal agricultural activity during its military period. This undisturbed time allowed nature to regenerate and maintain uncommon biodiversity.
