The Top 10 Biggest LEGO® Sets Ever

Last update: November 2021

On the 13th November 2020, we… sorry… let’s try that again…

On the XIII November MMXX, we released the LEGO® Colosseum. And it turned out to be the largest LEGO® set ever made, of all time – EVER – in the history of everything… EVER!

BUT since then, we’ve gone on to release sets that are even bigger like...*drumroll* ...the LEGO Titanic.

Yup, the most famous ship in the world now has its own LEGO brick version!


But exactly how big is this latest LEGO set? What are our other massive LEGO sets? What is the meaning of life? The answer to virtually all of these questions can be found below.

1. LEGO® Art World Map

With over 11,000 pieces, the LEGO Art World Map is not only our biggest LEGO set (in terms of piece count), but also a beautiful piece of wall art.

Put your own stamp on the world and create patterns in the oceans, get creative with the bright colors and choose which continent will be at the center.

Once built, you can track your travels, create your own bucket list using small, colored pins or simply just admire it as a unique piece of home decor. There’s no other world map out there that’s quite like it.

2. LEGO Titanic

Measuring 53 in. (135cm) long, the LEGO Titanic is currently our biggest LEGO set in terms of size. This 1:200 scale model of the historic ship makes it the ultimate building project with 9,090 pieces. It’s a whopper!

Packed with authentic details, inside and out, the set honors the original ship featuring a grand staircase, a boiler room, different cabins, lifeboats and even the first-class dining room.

Any history lover will enjoy recreating details like the promenade deck and swimming pool. You can even watch the piston engines turn inside as you turn the propellers.

The main question is...where do you put it? If you need some tips, here’s how to display huge LEGO sets at home...

3. LEGO Colosseum

A mere two millennia after the original was built, there is finally a Colosseum made of LEGO bricks. This incredible model is packed with fascinating details worthy of the most iconic amphitheater in history.

With 9,036 pieces in this set, making it our second largest ever, our designer Rok Zgalin Kobe explained that “the more the model was being perfected, the more pieces went into capturing its details.”

If you’re looking for a showstopping display piece for your home, this set could very well be it.

4. UCS LEGO Star Wars Millennium Falcon™

Now, we were going to make a joke about how funny it was that we used to think 7,541 pieces was actually *big*, but Chewbacca just walked into the room and seems to be indicating that we don’t write that. Either that or he’s hungry – we don’t speak Wookiee.

Chewy is one of seven minifigures in this eye-popping set that stands at 33 in. (83cm) long and 22 in. (60cm) wide. And (you won’t believe this), it can do the Kessel Run in 12 parsecs!

Be sure to check out the video from our Designer Video series, where two of the set’s designers go through its numerous features, in minute detail.

5. LEGO Harry Potter™ Hogwarts™ Castle

Despite containing 6,020 pieces, this castle still is able to surprise with the sheer amount of detail it fits in. From the guardian trials of the Sorcerer’s Stone, to the Chamber of Secrets™, all the way up to the unmissable office of Dolores Umbridge™ (literally unmissable…it’s bright pink).Fun fact: The designer curated the building experience to mirror that of Harry Potter™ when he first entered Hogwarts™, starting with the boats and the Great Hall before exploring the rest of the castle.

6. LEGO Creator Expert Taj Mahal

A landmark in the real world, a landmark in the LEGO world. This set was such a fan favorite that we re-released it in 2017 – a full 9 years after its initial release!

It contains 5,923 pieces and stands at over 16 in. (43cm) tall thanks to the stunningly rendered central dome. Who said mausoleums had to be depressing…?

7. LEGO Harry Potter Diagon Alley™

Stock up on potions, brooms, and (most importantly) everything in Weasleys’ Wizard Wheezes… The 5,544 pieces of this set produce a full meter-wide long version of the most famous magical shopping street this side of Hogsmeade™.

Combined with the 14 minifigures that this set comes with, there’s a real danger you might get lost in the crowd. If we get separated, meet us by Hagrid™.

8. LEGO Camp Nou – FC Barcelona

FC Barcelona fans and football lovers everywhere will appreciate this LEGO set of the iconic Camp Nou stadium – and not just because of its size!

With 5,509 pieces, this set is an authentic replica of the stadium featuring all the details any FC Barcelona fan would want to see in a collectible. From the impressive structure of the stadium, the field, to more intricate details like the players’ tunnel, stands, the VIP entrance and the Barça team bus, there’s plenty to look at every angle.

It even features the iconic “Més Que Un Club” motto on the Lateral stand.

9. Ultimate Collector’s LEGO Star Wars Millennium Falcon

The second-largest hunk of junk in our LEGO galaxy. This 2007 edition of the Millennium Falcon™ was made of 5,197 pieces, making it the first LEGO set to surpass the hallowed 5,000-piece mark. Perhaps in a few years’ time, it might be a Millennium Falcon set that breaks the 10,000-brick mark. Perhaps it won’t. Perhaps this writer has no clue.

We’ll never know.


While this multi-level vertical city set from THE LEGO NINJAGO® MOVIE™ might not top the list of most bricks, it’s got a strong case for being the most fun. Hidden compartments, moving mechanisms, 19 minifigures… Although its 4,867 pieces offered a pleasantly difficult building challenge, far more challenging was having to lie to your friends to say you bought this set for your kids.
