Chatsworth House in Derbyshire is starting its anual deep clean today after the festive period.
Every year a team take down the last of their Christmas decorations and begin their cleaning process.
This is the last of the 30 trees to be taken down, which have been up since the beginning of November.
30,000 books have to be dusted in the library and the crystals on their huge chandeliers have to be cleaned.
The house has 300 rooms, hundreds of windows, miles of carpet and dozens of curtains.
