22 LEGO Sets Are Retiring This Week, and the Falcon Leads With 7,541 Parts

LEGO.com Flags Twenty-Two Sets for Retirement This Week

Twenty-two sets carry the retiring soon flag on LEGO.com this week, and the spread is wider than usual. We pulled every one of them against our own parts database to see which exits actually matter and which are just seasonal clutter rotating out on schedule. The short version: five of the twenty-two break past 3,000 pieces, one of them has been on shelves since 2017, and at least one leaving now only arrived in 2025.

The theme breakdown tells its own story. LEGO Ideas and CUUSOO accounts for six of the twenty-two exits, more than any other line. Icons follows with five. Star Wars loses three sets, Marvel two, and Modular Buildings, Disney, Technic, Seasonal, Nike and Speed Champions each lose exactly one. That is not a random cull. It reads like a theme doing end of year housekeeping across its back catalogue rather than a single blockbuster being pulled.

We have full parts and minifigure data on twelve of the twenty-two, the ones large enough to matter for a display shelf or a serious collection. The other ten, mostly smaller sets from Technic, Seasonal, Nike and Speed Champions plus a few Icons and Marvel releases, are not detailed in our records against this week's flag, so we will not guess at their part counts. What follows is what we can back with numbers.

Star Wars Loses Its Two Biggest Ultimate Collector Builds

The Millennium Falcon, set 75192, is the heaviest hitter on the entire list at 7,541 pieces. It came out in 2017, which makes it the oldest set in this week's group by a wide margin, and it still ranks second by parts among the 814 Star Wars sets in our database. Only one Star Wars set has ever topped it. Ten minifigures ride along, including an aged, angry Han Solo variant and a black winged Porg, plus the usual Rey, Finn, Chewbacca and a gold C-3PO with printed legs. For anyone who has put off buying the 2017 Falcon because a reissue felt inevitable, this flag is the signal that the current version's run is ending.

The Venator-Class Republic Attack Cruiser, set 75367, is the other Ultimate Collector Series casualty. At 5,381 pieces it sits fifth by parts in the same 814-set Star Wars catalogue, and it is about 2,200 pieces lighter than the Falcon it retires alongside. It shipped in 2023 with just two minifigures, Admiral Wulf Yularen and Captain Rex, which tells you this set was built for the ship, not the crew. Losing two Ultimate Collector Series builds in the same week is unusual. The subline releases slowly and retires slowly, so seeing both go together suggests shelf space is being cleared ahead of new tooling.

LEGO Ideas Delivers Six Exits, More Than Any Other Theme

Ideas and CUUSOO is the biggest single contributor to this week's list with six sets leaving, and we have detail on five of them. The River Steamboat, set 21356, is the standout: 4,090 pieces, released in 2025, and the largest set the Ideas theme has ever produced in our 94-set record of that line. It carries no minifigures, which fits the theme's occasional habit of building for the model rather than the scene.

The Botanical Garden, set 21353, is close behind at 3,792 pieces with twelve minifigures, a full cast of visitors, gardeners, a barista and a photographer that turns it into more of a diorama than a single structure. It came out in 2024 and ranks third by parts among the 94 Ideas sets we track. The Starry Night, set 21333 from 2022, is smaller at 2,316 pieces but carries the theme's emotional weight: a single Vincent van Gogh minifigure and a design that turned a painting into a buildable object, something few other sets in the catalogue attempt.

Two more Ideas sets round out the group, and both are recent. Disney Tim Burton's The Nightmare Before Christmas, set 21351, has 2,193 pieces and eight minifigures including Jack Skellington, Sally and an unexpected Santa Claus figure. Willy Wonka and the Chocolate Factory, set 21360, arrived only in 2025 with 2,025 pieces and nine minifigures, and it is already flagged for retirement. A set leaving less than a year after launch is not the norm, and it is the single most surprising retirement on this week's list.

Icons Contributes Five Exits, but We Can Only Detail Two of the Big Ones

Icons matches Ideas closely with five sets leaving, and the two we can size up are both space builds with zero minifigures. The NASA Artemis Space Launch System, set 10341, packs 3,601 pieces and dates to 2024. It ranks twelfth by parts among the 86 Icons sets in our database, a reminder of just how many oversized builds that theme now carries.

The Endurance, set 10335, also from 2024, comes in at 3,011 pieces and ranks sixteenth in the same 86-set Icons list. Both sets skip minifigures entirely, which keeps the focus on scale and detail rather than a populated scene, and both will demand real shelf depth if you plan to display them assembled rather than boxed. The remaining three Icons sets on this week's retiring list are not detailed in our records, so we are not going to pretend we know their part counts. What we can say is that Icons, as a theme, is retiring proportionally more of its catalogue this week than Star Wars or Marvel.

Modular Buildings Retires Its Biggest Entry Yet

Modular Buildings only loses one set this week, but it is the theme's heavyweight. The Natural History Museum, set 10326, holds 4,015 pieces, the largest of the 22 Modular Buildings sets in our full database, ahead of even 2023's other release, the Jazz Club, by about 1,100 pieces. It shipped in 2023 with nine minifigures, including a curator, several museum staff, a window cleaner and two statue figures that double as display pieces inside the build itself.

For collectors who line the whole street up on a shelf, this is the one retirement worth planning around. Modular Buildings retires far less frequently than most themes, and the line rarely repeats a building once it is gone. A four thousand piece entry leaving after only two years on shelves is a shorter run than the theme usually gives its bigger releases.

Marvel and Disney Both Lose Their Biggest Recent Builds

Marvel loses two sets this week, and the one we can detail is unusually large for the theme. The X-Mansion, set 76294, runs to 3,093 pieces, which puts it fifth by parts among the 303 Marvel sets we track, a theme where most releases from its own launch year sit well under 300 pieces based on the comparable sets we hold. Ten minifigures come with it: a full classic X-Men roster including Rogue, Professor Xavier, Storm, Cyclops, Jean Grey, Iceman, Bishop, Gambit, Magneto and Wolverine. It is the kind of set that does not come around often in a theme built mostly around small vehicles and battle packs.

Disney's single exit is just as loaded. The Beauty and the Beast Castle, set 43263, has 2,916 pieces and twelve minifigures, tying it with the Botanical Garden for the richest minifigure lineup on this week's list. It ranks fifth by parts among the 257 Disney sets in our database and came out only in 2025. Belle, the Beast, Gaston, Lumière, Cogsworth and the rest of the household staff are all included, which makes this one of the few Disney castle builds with a genuinely full cast rather than two or three headline characters.

Technic, Seasonal, Nike and Speed Champions Each Lose One Set

The remaining four themes on this week's list each contribute a single retirement: one Technic set, one Seasonal set, one Nike set and one Speed Champions set. We do not have part counts or names for these four in our database against this flag, so we are not going to invent figures for them the way a press release might. What we can say from the pattern across the other eighteen sets is that this looks like a broad seasonal clearance rather than a handful of isolated decisions.

If you collect any of those four themes, treat this as a prompt to check your own local availability rather than wait for a restock. Small-theme retirements tend to move faster off shelves than the big showpieces, precisely because fewer units get stocked per store in the first place.

What These Part Counts Mean for Build Time and Shelf Space

Anything above 3,000 pieces on this list, and that covers eight of the twelve sets we can detail, means multiple evenings of building rather than an afternoon project. The Millennium Falcon at 7,541 pieces and the Venator at 5,381 sit in a different category entirely: these are sets you clear a weekend for, not a Tuesday night. The River Steamboat, the Natural History Museum and the Botanical Garden all fall in the 3,700 to 4,100 range, which in our experience translates to a build spread over several sessions if you pace yourself by bag.

Display space matters just as much as build time here. The Falcon needs a genuinely large shelf or stand once finished, the Natural History Museum sits in a Modular Buildings row that keeps growing, and the Botanical Garden's diorama format eats width rather than height. If your shelves are already full, this is a week to think about what comes down before anything new goes up, because several of these will not sit next to a mid-size set without dominating it.

The Full Ranking: Twelve Biggest Sets Leaving This Week, by Parts

Here is the complete order for the sets in this week's retiring flag that we can back with full data, ranked by piece count from highest to lowest.

1. 75192, Millennium Falcon, 2017, 7,541 pieces
2. 75367, Venator-Class Republic Attack Cruiser, 2023, 5,381 pieces
3. 21356, River Steamboat, 2025, 4,090 pieces
4. 10326, Natural History Museum, 2023, 4,015 pieces
5. 21353, The Botanical Garden, 2024, 3,792 pieces
6. 10341, NASA Artemis Space Launch System, 2024, 3,601 pieces
7. 76294, The X-Mansion, 2024, 3,093 pieces
8. 10335, The Endurance, 2024, 3,011 pieces
9. 43263, Beauty and the Beast Castle, 2025, 2,916 pieces
10. 21333, The Starry Night, 2022, 2,316 pieces
11. 21351, Disney Tim Burton's The Nightmare Before Christmas, 2024, 2,193 pieces
12. 21360, Willy Wonka and the Chocolate Factory, 2025, 2,025 pieces

Ten more sets carry the same retiring flag across Icons, Marvel, Ideas, Technic, Seasonal, Nike and Speed Champions, bringing the week's total to twenty-two. We have left them off the numbered ranking because we cannot confirm their part counts against our own records, and we would rather give you twelve confirmed entries than pad the list with guesses.

Our Priority Order for Collectors Who Cannot Grab All Twelve

If you can only chase a handful before they disappear, prioritise by scarcity of return, not just size. The Millennium Falcon is the obvious first pick since it is the oldest design here and the least likely to be reissued in this exact form. The Natural History Museum comes second: Modular Buildings retires slowly and rarely repeats a building, so a two-year-old entry leaving this early is worth moving on quickly.

Willy Wonka and the Chocolate Factory deserves a higher spot on your list than its 2,025 pieces might suggest, purely because of how fast it is retiring. A 2025 release leaving before its first birthday is not typical, and it suggests demand or licensing pressure we cannot see from the outside. The Venator and the Botanical Garden follow for the same reason as the Falcon: large licensed builds in mature theme lines rarely get a straightforward second run.

The two Icons space sets and the X-Mansion sit lower on our list, not because they are lesser builds, but because Icons and Marvel both cycle their catalogues more frequently, so a similar scale or theme is more likely to resurface within a year or two.
