Edward Montagu's rebuilding of Hinchingbrooke

Edward Earl of Sandwich made considerable alterations here in 1661, adding two storeys to the western range together with an addition at the north- west corner, formed a kitchen in the projecting northern wing, and rebuilt the staircase. He appears to have done other works, including the building of the garden wall next the road in 1663-4.

The Earl of Sandwich was second cousin to and patron of Samuel Pepys and Hinchingbrooke and its owner figure largely in his Diary. The earl immediately started elaborate alterations and additions to the Elizabethan mansion. Under 9 December 1660 Pepys notes that he (Pepys) has commissioned Mr. Kennard, master joiner at Whitehall to go to Hinchingbrooke about the alterations and nearly twelve months later he complains that they are very backward.

On 15 October 1664 he visited Hinchingbrooke and found the "water-works and the Ora, which is very fine; and so is the house all over, but I am sorry to think of the money at this time spent therein."
