The 12th Duke of Devonshire plans to move back to his family seat at Chatsworth House in Derbyshire.
The duke has announced he will move to Chatsworth
Peregrine Cavendish, who inherited the title after his father's death a year ago, hopes to be living at the stately home by the end of the year.
As he unveiled a portrait of the 4th Duke of Devonshire, the Duke said he was looking forward to moving in.
The Duke previously said he had no plans to move to the ancestral home and was staying in Bolton Abbey, Yorkshire.
Shortly after his father's death in May 2004, the duke said he and his wife would remain at Bolton Abbey, part of the Chatsworth estate in North Yorkshire, but he would be a frequent visitor to Chatsworth.
His mother, the Dowager Duchess of Devonshire will continue to live on the Chatsworth estate.
