The original house was a monastic building but Sir Edward Montagu, Lord Chief Justice to King Henry VIII, purchased it in 1528 just prior to the Dissolution of the Monasteries and began to convert it into a mansion. Most of the present building is the work of Ralph Montagu, 1st Duke of Montagu (d.1709) who inherited the house in 1683.
Montagu was a former English ambassador to France, and Boughton House shows strong French architectural influences. His son, John Montagu, 2nd Duke of Montagu, made little alteration to the house, but made sweeping changes to the landscape and gardens after his return from campaign in Europe with his father-in-law, John Churchill, 1st Duke of Marlborough.
Following the death of George, 3rd Duke of Montagu, in 1790, the house passed, through the marriage of his daughter, Elizabeth, to Henry Scott, 3rd Duke of Buccleuch, 5th Duke of Queensberry. Boughton House was little used or altered from the mid-18th century, but was well cared for. Because of this it has some of the best preserved baroque state rooms in the British Isles.
Boughton House hosts the Montagu Music Collection, containing a number of unknown sources of Italian baroque music.
