The Windsor Castle Stakes, a Listed race over 5 furlongs, is staged on the final day of the Royal meeting. It was first run at the Royal meeting in 1880, although prior to that a similarly named race was contested at Egham, and during the Second World War Windsor hosted a race called the 'Windsor Castle Stakes'. Furthermore, The Windsor Castle Stakes at Royal Ascot over the New Mile was first run in 1839 and is included in this section.
