Prince Harry will marry Meghan Markle this weekend against the stunning backdrop of Windsor Castle. It's the Queen's favourite home, surrounded by the greenery of Windsor great park. But did you know the royal town - like Meghan - has connections 5,000 miles away in California?
So, while the world's media heads to Berkshire for the royal wedding, we sent Sangeeta to Windsor USA to find out more about its unofficial twin.
Sangeeta talked to Steve Lehmann of Windsor Historical Society; Jim Du Vander, resident; Amy Whiteley, teacher; and Mark Elcombe, Sonama-Cutrer Vineyard.
