Windsor CastleNestled atop a hill in a charming market town, Windsor Castle was founded by William the Conqueror in the 11th century. Over the centuries this 900-year old site has been extensively rebuilt and remodelled thanks to the 39 monarchs who have lived there. To this day it is still a working palace, as well as Queen Elizabeth II’s favourite weekend residence. Remember to look out for the Royal Standard flag - if it’s flying over the castle, it’ll mean Her Majesty is at home. Will you be lucky enough to get a wave from the Queen?There is so much to see at Windsor Castle - from the stunning State Apartments to the gigantic, incredibly detailed Queen Mary’s Dolls’ House and St George’s Chapel (the resting place of Henry VIII and other monarchs), this royal venue promises to be an unforgettable experience.
