The LEGO Lion Knights' Castle (10305) is worth buying if you want the castle itself, and pointless if you want an appreciating asset. Brickset lists it at $399.99 for 4,514 pieces, retired on 31 December 2025, and Brick Ranker has sealed copies at $400.55, which is 0.1 percent above retail. Eight months off shelves have moved it almost nowhere.
What $399.99 bought
Brickset lists 10305 with 4,514 pieces at $399.99 in the US and £344.99 in the UK, released on 3 August 2022 for LEGO's 90th anniversary. It carries an 18+ rating and lands at 8.9 cents per piece. It was designed by Carl Merriam, Mike Psiaki and Milan Madge, and it holds 4.6 out of 5 from 668 Brickset ratings, one of the higher scores in the Icons line.
It comes with 22 minifigures, 19 of them unique. That figure count is the single biggest difference between this and most sets in its price band, and it is a large part of why the castle still reads as good value even now.
The model is 38 by 44 by 33 cm. For 4,514 pieces that is compact, because the castle builds upward on a rocky outcrop instead of spreading flat across a baseplate. It fits on a normal shelf, which cannot be said of most sets this size.
The build is the reason to own it
Jay's Brick Blog scored it 5 out of 5 and called it "the Castle set of your dreams," describing "clever technique after clever technique" through the build. Two details from that review carry real weight for a buyer.
First, there are no stickers. At 4,514 pieces that is close to unheard of, and it removes the single most common long-term complaint about large display sets. Second, the set ships with two instruction books, so two people can build it at once. The reviewer built it across three days and suggested taking a week or more.
The play features "work incredibly well" according to the same review, and the minifigure roster is called superb, with Queen Lionne singled out as one of the most-loved Castle characters and a genuine addition to the theme's lore rather than a repackaged knight.
Where it falls short
The criticisms are narrow. Magisto, the wizard, "doesn't have printing" on his torso, which the reviewer flagged as a miss on a figure that should have been a highlight. The reviewer also wished for more animals, naming chickens, rats and goats as absences.
The bigger objection is the one you would expect. Jay's Brick Blog called the set "quite expensive and might be out of reach for some people," and $399.99 for a set with no licence attached is a lot of money. Critics collected by other outlets made the same point, arguing that $50 less would have moved the verdict from recommended to essential.
The value has gone nowhere
Brick Ranker valued sealed copies at $400.55 using sales logged between February and August 2026, and reports growth of 0.1 percent since retirement. That is flat. Brickset's own set page is more pessimistic, showing a new-condition value nearer $380, so the two trackers sit about $20 apart, which is itself a useful reminder that a single valuation is an estimate rather than a price.
Either way the conclusion holds. Eight months after leaving shelves, 10305 has not started to climb. That is not unusual this early, since retailer stock takes time to clear, but it does mean anyone buying now for resale is paying full retail for a set with no proven momentum. Flat is easy to miss when nobody is measuring, which is the argument for keeping a collection valued somewhere like Stud Vault.
Castle against castle
Hogwarts Castle (71043) is the obvious comparison and it flatters the Lion Knights' Castle. Hogwarts is $469.99 for 6,020 pieces, a better 7.8 cents per piece, but it is still in production and Brick Ranker has it 18.4 percent below retail. The Lion Knights' Castle costs less, holds its price, gives you 22 minifigure-scale figures instead of microscale trophy figures, and comes with no stickers at all.
For a different flavour of Icons flagship at a similar price, the LEGO Eiffel Tower 10307 review covers the same question from the architecture side.
Build it, do not bank it
Buy it if you want a castle you will look at for a decade and you can find a sealed copy at or near $400. The 8 here reflects a genuinely excellent build let down only by a price that reviewers flagged at launch and by a resale market that has so far ignored it.
Skip it if the plan is to store the box and sell in two years. Flat is flat, and unlike a licensed set there is no film or series schedule to push demand. Buy this one to build it.
