Bolsover Castle is to be brought back to life as part of a £1 million project.
Recognised as one of the most important Jacobean buildings in the country, the 17th century castle will undergo refurbishment work ready for spring next year.
There will be a new introductory exhibition and film, along with discovery boxes, in the Riding House Range and a multi-media guide to further enhance the interpretation, complete with games for the whole family.
The exterior will also be treated to repairs with the high-level wall walk to be re-instated and open for visitors for the first time in almost 400 years.
The castle was once used by William Cavendish, Duke of Newcastle, a sophisticated, master horseman and courtier to King Charles I, as a retreat for entertainment and cultural pursuits high above the Derbyshire countryside.
A spokesman said: “The new interpretation will offer visitors to take another look at the surviving architecture and appreciate the vision and the background to a cultured nobleman’s life four centuries ago.”
