Phyllis Court is a building that currently houses a private members club in Henley-on-Thames, Oxfordshire, England, situated by the River Thames.
[citation needed] In the mid 17th century, Phillis Court was the home of Sir Bulstrode Whitelocke (1605–1675), parliamentarian and Lord Keeper of the Great Seal, who before his death gave it up to his son William Whitelock, later Tory member of parliament for the University of Oxford.
Later it housed a top-secret unit making important photographic mosaics and models of the future Allied landing beaches in France and planning many raids including the "Dambusters".
The clubhouse ended the war on a more peaceful note being used by the American Red Cross as a rest centre for war-weary airmen.
[citation needed] On 6 November 1998, Queen Elizabeth II visited the Club before travelling upriver by boat to open the River and Rowing Museum.
