The estate contains the remains of Roman villas, and was recorded in the Domesday Book as ‘Madmintune’ – a name that hints at its deep historical roots.
In the 17th century, the Somerset family made Badminton their principal seat after Raglan Castle was damaged during the English Civil War. Henry Somerset, later created the 1st Duke of Beaufort for his loyalty to the crown, rebuilt and expanded Badminton House in the 1660s. His wife, Mary Somerset, 1st Duchess of Beaufort (1630–1715), was a pioneering botanist who enriched the gardens with rare plants from around the world. Her florilegium of over 170 botanical paintings remains at Badminton, while her herbarium, later gifted to Sir Hans Sloane, is now part of the Natural History Museum, preserving her lasting contribution to horticulture.
