For 40 years before they purchased the deeds from the de Baglion family, the chateau was completely vacant with no electricity, heating or running water.
As the couple have opened up their home to the public, they charge a fee for visitors to stay at the property or to host an event there.
A wedding package ranges from £19,000 and £38,000 but to stay there would set you back around £5,000 to £6,000.
However, prices and availability do tend to change and if visitors want a night under the stars, they can hire out one of the geodesic domes installed on the land for a cost of £350 a night.
Escape to the Chateau is available to stream on All4.
