Noah Schnapp revisits Castle Byers in aStranger Thingsseason 5 behind-the-scenes video. Introduced in season 1, Castle Byers was a fort that Will (Schnapp) and his brother, Jonathan (Charlie Heaton), had made. When Will was trapped in the Upside Down,he hid from the Demogorgon in the alternate dimension’s version of Castle Byers. Will has gone through a great deal since then, with his story poised to conclude inStranger Thingsseason 5, which is still filming.
On X,Ross Duffershared a video ofSchnapp bidding farewell to the last day of filming on the Castle Byers set,which included providing a behind-the-scenes tour of the iconic location. Check out the video below:

Schnapp refers to it as"the last day forever"and reminisces about how he first filmed scenes in Castle Byers when he was 10 years old and how he is now filming there a decade later. He emphasizes that this is the Upside Down version of Castle Byers and points out Will’s drawings on the walls.

While Schnapp’s video is nostalgic, it is also an intriguing tease for season 5. Will destroyed Castle Byers in Hawkins, Indiana when he was upset, but Schnapp points out that this is the Upside Down version of the location. This aligns with a previous behind-the-scenes photo that was shared by him and a younger version of his character both being inside Castle Byers. It seems thatWill needs to return to the place where he hid for most of season 1, with this location potentially proving useful in the quest to defeat Vecna (Jamie Campbell Bower).
