The Nude in the Attic

The compelling and sometimes scandalous family stories behind two very different National Trust houses are revealed.

In Knole House, the sprawling Tudor ancestral seat of the Sackville family, a life-size nude statue of 18th-century ballet dancer Giovana Zanerini, commissioned by her lover John Frederick, is being conserved to slow the aging process and restore her legendary looks. Two other heirlooms at Knole - a set of 400-year-old rolled-up animal skin parchments - are so delicate that they haven’t been unrolled for many years.

At the traditional Lake District farmhouse Townend, a key part of the archive of the Browne family of yeoman farmers - a bound volume of 18th-century letters - is being conserved using traditional book-binding skills, and scientific paint analysis has revealed the house's original Victorian paint scheme.
