Kew Palace is a British royal palace within the grounds of Kew Gardens on the banks of the River Thames. Originally a large complex, few elements of it survive. Dating to 1631 but built atop the undercroft of an earlier building, the main survivor is known as the Dutch House. Its royal occupation lasted from around 1728 until 1818, with a final short-lived occupation in 1844. The Dutch House is Grade I listed, and open to visitors.
