Visitors have been getting a first- hand glimpse at how the many historic trinkets and treasures are maintained at one of the county's stately homes.
The Store has been opened at Calke Abbey to show people some of the techniques used to maintain the building.
One of the more unusual items on show is a taxidermy pine marten – similar to a weasel – which was used as a purse.
Assistant house manager Emma Seymour said she did not know who the purse had belonged to.
She said: "It was made at the time when it was perfectly acceptable to have taxidermy hanging round your neck."
The Store has now been opened to the public and Ms Seymour said it was a great way to begin a tour of the house.
She said: "It is filled with clutter and things and it is a good introduction to the rest of the house.
"When we had it as the study before, it was 'too clean'.
"Now being a jumble of bits and pieces of collections it sets the scene for the rest of the building."
The house was built sometime between 1701 and 1704 and is a grade one-listed building. The estate, in Ticknall, is currently in the care of the National Trust.
It was owned by the Harpur family for almost 300 years before it was handed to the trust in 1985.
The Store room was designed to portray how the house would have looked in the 18th century.
Ms Seymour said many people had already enjoyed what the room has to offer so far and expected many others to visit in the future.
She added: "It does give you an insight into how we look after different collections at the National Trust.
"The volunteers show you through the bits and pieces we would use at Calke, you get to have a proper look at them."
