1. Windsor Castle
What is it? The Queen’s weekend gaff and the venue for Prince Harry and Meghan Markle’s wedding. It was founded by William the Conqueror in the eleventh century and is now the oldest and largest inhabited castle in the world.
Why go? To immerse yourself in royal history and be dazzled by the lavishly gilded interiors. Don’t miss Queen Mary’s Dolls’ House, a miniature replica of a 1920s mansion complete with electricity and running water.
