Be still, our anglophilic hearts. According to the British TV publication the Radio Times, the Downton Abbey lot will leave Hampshire’s Highclere Castle—the Jacobethan country manor that doubles as the Crawley’s fictional estate—for Alnwick Castle. For those of you who aren’t Harry Potter trivia buffs, Alnwick Castle, the stately seat of the Duke and Duchess of Northumberland, is better known as friggin’ Hogwarts School of Witchcraft and Wizardry in the film adaptions of J.K. Rowling’s books.

The Radio Times notes that Downton Abbey is filming at Alnwick through August 8—a report that seems to be substantiated on Alnwick’s official Web site, which alerts potential visitors that “various areas of Alnwick Castle will be closed or have limited access on 28th July – 8th August (inclusive), due to the filming of a major ITV period drama.” The Duke of Northumberland also seems to confirm the speculation in a statement issued to his local newspaper: “As we know from experience, filming somewhere like Alnwick Castle can be very disruptive, but when we received ITV’s enquiry, my wife and I felt that we could not miss the opportunity for the castle and town to be associated with such a hugely popular drama series, and we consider it a great honour to be asked to participate.”

Meanwhile, the blabbermouths over at Sovereign Taxis seem to have outed the whole covert operation on July 29, with the blunt tweet: “Start of another busy day with the Downton abbey crew. — at Alnwick Castle.”

There are no current reports of what exactly might be filmed on Alnwick’s expansive property—the exteriors of which (witch!) have been used for many a Quidditch match. But Broadway World speculates that since much of the series’ fifth season has already been filmed, the castle could be the setting for the drama’s fifth annual Christmas special.

If we’re lucky, maybe Hogwarts’ residue witchcraft will rub off on Lady Edith. We’d love to see the ill-fated Crawley sister use sorcery to even the score with Mary.
