As part of its San Diego Comic-Con showcase, Lego has unveiled the next large-scale Batman building set for adults and collectors. Batman Arkham Asylum is a massive 2,953-piece Lego interpretation of the psychiatric hospital in Gotham City where many of the Caped Crusader’s longtime foes are often confined (before escaping again). This highly detailed recreation of Arkham Asylum comes with 16 minifigures and has a modular design that Lego says can double as a 24-day buildable Advent Calendar.
Lego DC Batman Arkham Asylum launches September 9 and is available to preorder for $300 exclusively at the Lego Store.
Lego DC Arkham Asylum (2,953 Pieces)
$300 | Releases September 9
Though Lego DC Arkham Asylum isn’t officially categorized as an Advent Calendar, the build is seemingly a great fit for one-piece-per-day setup of the popular holiday countdown calendars. You can build one chunk of the building each day for 24 days. Considering it comes with sprawling collection of 16 Batman heroes and villains as minifigures, you’ll get a new character most days, too.
Here’s the full list of minifigures included with Lego DC Batman Arkham Asylum:
- Batman
- Robin
- Batwoman
- Catwoman
- Batwing
- The Joker
- Harley Quinn
- The Riddler
- The Penguin
- Bane
- Mr. Freeze
- Poison Ivy
- Scarecrow
- Killer Croc
- Security Guard (x2)
Lego’s actual Advent Calendars are substantially smaller than this–the 2025 editions retail for $45 and release September 1–so this would be quite the lavish choice for your countdown this year.
You can, of course, completely ignore the Advent Calendar approach and build the entire set in one weekend. The full three-story asylum is 10.23 x 9.84 x 12.59 inches. If that sounds a bit small based on the piece count, it’s because this is more densely packed with a huge emphasis on the rooms inside. Plus, unlike some Lego sets that don’t have exterior walls around the sides and back, Arkham Asylum is a complete structure.
After finishing the build, you can separate the three floors to show off and make changes to the furnished rooms and holding cells. Sections on each floor are designed to be easily removable, too. Prison cell doors can swing open with the press of a button, and you can let the villains decorate their cells with 65 stickers pulled from Batman lore.
All of the minifigures come wit transparent stands that attach to the building or front yard. The stands are designed to create active poses, as if you paused a movie.
The build also comes with an Arkham Asylum inmate transport van. In the promotional images, the van is operated by Harley Quinn, who is clearly on the verge of successfully breaking Joker out of the hospital.
San Diego Comic-Con Lego Sets
Arkham Asylum is one of several exciting Lego sets making its debut at SDCC. Lego also unveiled its Game Boy building set, a 421-piece replica of the original Nintendo Game Boy. The Lego Game Boy releases October 1, the same day as the newly announced Stranger Things BrickHeadz. The four-pack of buildable figures is only the second Stranger Things Lego set–the first launched back in 2019–and arrives just in time for the long-awaited final season on Netflix. Lego will also expand its lineup of Wicked building sets with six new products, including display models for adults and playsets, on September 1.
