Hertfordshire

Ellie Harrison peeks through the keyhole of some of Hertfordshire's homes and gardens. Her journey starts near St Albans planting trees for a forest of the future, before she heads over to Scott's Grotto in Ware, a puzzling remnant of 18th-century high society.

Ellie visits the gorgeous house where Barbara Cartland, queen of the romantic novel lived, before heading to Knebworth to learn the story of another inspirational lady.

Ellie's journey comes to an end in Perry Green, at the former Hertfordshire home of one of the world's most-celebrated sculptors - the late Henry Moore.
