Royal children tour HBO's Harry Potter set at Windsor Great Park

The Prince and Princess of Wales’s youngest children visited the set of HBO’s upcoming Harry Potter television series this week at Windsor Great Park, where they toured a Hogsmeade Station set and watched night filming, officials said. Princess Catherine accompanied Prince George, Princess Charlotte and Prince Louis to the woodland site; Prince William was in Scotland visiting King Charles III at the time. During a return visit on Friday night the children met members of the young cast and the series director, and Prince Louis was given a short ride on a Hogwarts Express locomotive running along about half a mile of track through the woods.

Production on the television adaptation began in July and has been filming at multiple locations around the United Kingdom, with the first season shooting this year. The series is expected to debut on HBO in early 2027 and is planned as a long-running project. The Hogsmeade Station set built at Windsor Great Park sits a short distance from the royal family’s residence in Forest Lodge, allowing relatively quick access for the royal visit.

The young actors cast in the main roles include Dominic McLaughlin as Harry Potter, Alastair Stout as Ron...
