Wentworth Woodhouse in Rotherham has been awarded £7.6 million by the chancellor of the exchequer in his Autumn Statement.
Philip Hammond awarded the historic Grade 1-listed building the grant to help towards urgent repairs. The mansion and its 82-acre estate is also facing a £50 million restoration bill.
The former home of the Fitzwilliam mining family had fallen into disrepair partly due to the number of old mining shafts in the area.
Conversation group Save Britain’s Heritage believes the mansion needs £50 million of investment to return it to its original state.
The Wentworth Woodhouse Preservation Trust (WWPT) has £7 million in place to buy the building from its current owners the Newbold family.
The building is one of Europe’s largest stately homes and was the inspiration for Pemberley in Jane Austin’s Pride and Prejudice. It has recently been the background for the BBC mini-series Jonathan Strange and Mr Norrell.
