Overton Down

Overton Down is an experimental archaeological site on Wiltshire's chalk hills built specifically for scientific study. The location features purposefully constructed earthworks and structures designed to monitor how materials and structures deteriorate over time in natural conditions.

The experimental project began in 1960 as a study of how archaeological structures and materials deteriorate over extended timeframes. Since then it has served as a working laboratory for understanding decay processes.

Researchers at Overton Down examine the deterioration patterns of artifacts and materials to understand ancient construction methods and preservation techniques.

The site sits on open hills and is accessible on foot, with parking available near the entrance. Marked pathways guide visitors through the rural Wiltshire landscape without steep terrain or major obstacles.

The experiment is designed to run for 128 years, concluding only in 2088. This unusually long timeframe allows researchers to observe changes that would remain invisible in conventional archaeological study.
