Bowood House has won the 2014 Garden of the Year Award.
This national award is designed to recognise the importance of gardens with outstanding horticultural and public appeal, either in their own right or as the setting for a historic house.
The Marquis of Lansdowne said: "There are few accolades which could be more rewarding for all of us at Bowood.
"To know this award has been adjudicated solely by our visiting public, says it all. "So 'thank you' to our visitors and congratulations to our dedicated staff. Bowood continues to evolve.
Charles Cator, deputy chairman of award sponsor Christie’s International, said: "It is particularly exciting that the superb gardens at Bowood should have won the 2014 HHA/Christie’s Garden of the Year Award as they are a testimony to great care, passion and dedication of Lord and Lady Lansdowne in nurturing and continually enhancing this sublime setting, which is enjoyed by so many visitors each year.
Richard Compton, president of the Historic Houses Association said: "The beautiful gardens at Bowood House, surrounded by 'Capability' Brown's sublime park have been enjoyed by many thousands of people since they were opened to the public in 1975.
"The enormous amount of work and skill put into their immaculate presentation by Lord and Lady Lansdowne and their team of dedicated gardeners pays off handsomely as all visitors can see for themselves.
The award is in its 30th year. Capability Brown created the Bowood parklands.
