The two-part series will follow the castles as they get ready for their biggest time of year, Christmas.

Highclere is famous for featuring as the family house in Downton Abbey and is home to the Earl and Countess of Carnarvon. 

Viewers will discover what life is really like at the castle and go behind the scenes with the small team who keep everything running as they prepare for the festive period.

Warwick Castle dates all the way back to 1068 and was built on the order of William the Conqueror. 

As soon as Halloween is over, Warwick Castle begins transforming into a winter wonderland, which has been especially challenging this year with the November lockdown and introduction of the tier system. 

Despite the challenges, the staff still plan to impress visitors with stunning decorations, a 745-metre square ice rink, a real-life Santa experience and a new light trail snaking through the castle grounds. 

Commissioning editor at Channel 4, Becky Cadman, said: “Highclere Castle and Warwick Castle are a pair of stunning locations where Christmas celebrations are truly spectacular. 

“Our exclusive access to these historic sites will offer a fascinating insight into both the traditions and more modern approaches of each, as well as revealing how they’ve adapted for a very different Christmas this year.”

Christmas at Highclere Castle will air at 9pm Wednesday 16 December and Christmas at Warwick Castle will air at 9pm on Tuesday 22 December.
