For writer Adam Nicolson, attachment to place goes deep. He grew up in Sissinghurst Castle, one of the most beautiful places in England, home to the celebrated garden of his grandmother, the poet Vita Sackville-West. When he returned as an adult he was astonished and saddened to see that the working farm at the garden had disappeared. He tells the story in a book called "Sissinghurst - An Unfinished History." He tells Anne Strainchamps it was a magical place to grow up.
