Christie's main London saleroom is on King Street in St. James's, where it has been based since 1823. It had a second London saleroom in South Kensington which opened in 1975 and primarily handled the middle market. Christie's permanently closed the South Kensington saleroom in July 2017 as part of their restructuring plans announced March 2017. The closure was due in part to a considerable decrease in sales between 2015 and 2016 in addition to the company expanding its online sales presence.
