And that’s a wrap! After 140 days of shooting, filming has officially concluded on Season 4 of Downton Abbey. Jon East, the BAFTA-award winning English director heading the finale, was kind enough to share the good news via his personal Twitter with a series of messages that have us all kinds of excited.

“Early start for last day shooting Downton Abbey 4. We finish as we started, with a huge set piece, dozens of extras, vast set, crane etc!” Jon wrote on Friday, August 16.

That “vast set” for at least part of the Christmas special is believed to be Royal Holloway, University of London — a gorgeous 135-acre campus opened by Queen Victoria back in 1886.

Two lucky bystanders on campus actually snapped photos of the cast filming in Founders Quad. @Matt_Willis6 and Kindle-the-Stars our gratefulness knows no bounds.

Although we can’t see much in the shots, at least no wayward delivery trucks are in this year’s Christmas special...

At least, that’s what we thought until we saw this tweet from our new BFF, Director Jon: “Ealing Film Studios, where we have just finished shooting series 4 of Downton Abbey.”

It’s hardly the scenic (or historically accurate) locale judging from the photo below. And so the plot thickens.

So when will we finally get to see the show? The UK premiere is set for September, and seeing as Jon tweeted that editing on the Christmas Special just started on Wednesday, August 21, we’re guessing the first episode of a predicted nine can’t be far off.
