Stowe House in the parish of Kilkhampton in Cornwall, England, UK, was a mansion built in 1679 by John Grenville, 1st Earl of Bath (1628–1701) and demolished in 1739.
The Grenville family were for many centuries lords of the manor of Kilkhampton, which they held from the feudal barony of Gloucester, as they did their other principal seat of nearby Bideford in Devon.
As well as a real tennis court and chapel, there was an extensive deer park with carriage driveways and formal gardens including fountains, statues and fish ponds.
The inheritance was divided between the second earl's sisters and a cousin George Granville, Baron Lansdowne (died 1735), after whose death the family became extinct.
The most notable surviving fabric of Stowe House exists as follows: These articles, with many others, were taken to Bude, shipped to Barnstaple, and thence carted to South Molton.
