Work on the first season of HBO's Harry Potter—adapting The Philosopher's Stone—will continue into next year, and sets are still being constructed, including one very familiar location.

Thanks to The Sun, we have a first look at the all-new Diagon Alley, though it's likely to be familiar to many of you. Much of the signage differs, and the buildings aren't exactly the same, but at first glance, this doesn't look all that different from what we saw in the movies.

The tabloid spoke with the source who took these photos, and they promised that there will be elements of Diagon Alley that are new to viewers.

"There is a whole new part that wasn’t in the first films. It’s completely different and it has a different feel," they shared. "The street is two layers. The wand shop is a little different but the main difference is the bank."

"I don’t think they’re allowed to do the same as the films, apart from the general Harry Potter story, so the design will be very different," they continued. "The joke shop is in a different place and does not look anything like the original."

Ultimately, the Harry Potter TV series is based on the same J.K. Rowling novels as the movies, so expecting anything drastically new would be foolish. We've already seen that the Hogwarts Express is identical. However, enough subtle changes—including a deeper dive into the characters and stories from books glossed over or missed in theaters due to time constraints—should help make the show feel entirely its own.

It's interesting that changes have been made to the layout of Diagon Alley, and the new Gringotts sounds intriguing, given what an iconic structure it was on the big screen.

We still don't know when an official look at the series will be revealed, but even with set photos like these finding their way online, it likely won't be until next year.
