The Devonshire Collection Archives stored at Chatsworth include 450 years of documents about the family and their two main estates. In 2019, the Duke and Duchess visited Sotheby's to view "Treasures From Chatsworth": art and artifacts from Chatsworth House that would be displayed in New York. During the 2022 European heatwaves, a section of the Great Parterre that formerly occupied Chatsworth's South Lawn were revealed as the grass and soil dried out, showing the patterns of earthworks that had been used to construct it. As the lawn's grass has shorter roots, it dried out faster, creating a contrast that allows the structure to be viewed with the naked eye.

The façade is dramatic and sculptural with ionic pilasters and a heavy entablature and balustrade. The existing heavy and angular stone stairs from the first floor down to the garden are a 19th-century replacement of an elegant curved double staircase. The east front is the quietest of the four on the main block. Like the south front it is unusual in having an
