Biggest Lego sets

1. World Map

World Map Lego biggest set

Set no: 31203
Pieces: 11695

Release date: 2021
Age: 18+

Adult Lego builders looking for the ultimate large-scale Lego project will get a kick out of this one-of-a-kind World Map set — it’s currently the biggest Lego set (by piece count) and contains a total of 11,695 pieces!

This Lego Art set measures over 25.5 inches (65 cm) high and 40.5 inches (104 cm) wide, offering AFOLs, map illustrators, and travelers a challenging brick-building experience. It’s an incredibly creative take on your classic world map!

Unlike standard Lego sets, this Lego Art edition features rounded, mosaic-like bricks, which is also an excellent way for Lego hobbyists 18+ to experience something a little different. Due to its large size, it’s also the ideal venture to take on with family and friends, much like your traditional puzzle!

In addition to vibrant colors and a stunning layout, this set allows you to create different configurations. It also includes a hanging hook to display on your wall, a QR code to access a custom soundtrack to listen to as you build your project, and special pins to track places you’ve been or dream of going to.

2. Eiffel Tower

Eiffel Tower Biggest Lego set

Set no: 10307
Pieces: 10001

Release date: 2022
Age: 18+

Lego has developed several Eiffel Tower sets over the years, but I can tell you, none of them have been quite like this! The jaw-dropping 360º Lego Icons Eiffel Tower is one of the biggest Lego sets ever made and is officially the tallest.

Measuring over 58.5 inches (149 cm) high, 22.5 inches (57 cm) wide, and 22.5 inches (57 cm) deep, your final display will consist of 10,001 bricks. It’s a dream come true for travelers and fans of classic European landmarks and cities — not to mention a fantastic gift for challenge-seeking AFOLs.

This is definitely a step up from smaller Lego Architecture sets! You’ll get a real-life feel of this Parisian masterpiece thanks to all of the incredible features in this set: arches, railings, observation platforms, and elevators, as well as scenic details like picturesque French lamposts, benches, and charming shrubs and trees.

Instructions for this set have also been sequenced to match Gustave Eiffel’s original building process: the cherry on top for anyone fascinated by the legendary engineer. This is (unsurprisingly) a pretty expensive set, but well worth the buy if you’re looking for one-and-only Lego show-stoppers!

3. Titanic

Titanic Lego biggest set

Set no: 10294
Pieces: 9090

Release date: 2021
Age: 18+

Another set history buffs will fall head over heels for is the 9,090-piece Titanic Lego Icons edition. It’s one of the biggest Lego sets ever made and, to this day, the longest. 

Suitable for hobbyists ages 18+, this brick ship measures approximately 53 inches (135 cm) long, 17.5 inches (44 cm) high, and 6 inches (16 cm) wide. It’s designed in three sections and packed with detail to faithfully recreate the “Ship of Dreams.”

Features like the grand staircase, smoking lounge, boiler room, pool, promenade, and dynamic pieces like adjustable masts and propellers are only some of the special components to appreciate in this set. A stand and a nameplate are also included to ensure your model is showcased with the brilliance it deserves. 

Lego has a few tips for displaying big sets you might find helpful! There is also a Lego alternative of a Titanic model that’s smaller and much cheaper if you’re not ready to take to leap. However, if you’re looking for days of brick-building fun and an epic addition to your Lego collection, this Titanic model is definitely it. 

4. Colosseum

Colosseum biggest Lego set

Set no: 10276
Pieces: 9036

Release date: 2020
Age: 18+

The Roman Colosseum is one of the greatest architectural wonders of the world, and this 9,036-brick Lego set is a creative way to bring a little bit of its innovative structural beauty to your home or office.

Listed as one of the biggest Lego sets, this model measures 10.5 inches (27cm) high, 20.5 inches (52cm) wide, and 23.5 inches (59cm) deep. What I love about this set is that while large and complex, it’s relatively lightweight and easy to transport; you won’t have the same space-seeking dilemma as with other big Lego sets!

This is the perfect gift for anyone who loves travel and holds particular intrigue for ancient Rome and history. Or hey, maybe you’re just a huge fan of the Gladiator movie! Fun fact: scenes from the movie were filmed in a small replica of the iconic Italian amphitheater in Malta.

The model features three stories packed with detail, including everything from an exquisite façade to columns of the Doric, Ionic, and Corinthian orders. Since it’s slightly smaller than the sets listed above, it’s a great pick for adult beginners to segue into more elaborate brick-building ventures.

5. Millennium Falcon™

Millennium Falcon biggest Lego set

Pieces: 7541

Release date: 2019
Age: 16+

In case you’ve been wondering when we were going to mention a Star Wars Lego set, rest assured, that moment has arrived — and you’re going to love it. Much like Lego’s Eiffel Tower sets, there have been multiple versions of Star Wars’ emblematic Millennium Falcon, but this one takes the cake regarding size and piece count.

Measuring over 8 inches (21cm) high, 33 inches (84cm) long, and 23 inches (60cm) wide, this is the largest Lego set for the franchise and will guarantee AFOLs hours of brick-building leisure: 7541 bricks included.

This set stands out for its sublime design, resulting in an epic collector item every Star Wars fan will dream of owning. It’s the perfect model for an impactful display and one of the best Lego sets for ambitious adults on the hunt for an exceptional brick-building adventure. 

Representing a central reference in the Battle of Hoth in Star Wars: The Empire Strikes Back, this AT-AT model features posable legs, opening hatches, rotating cannons, a bomb-drop hatch, and more. The set also contains nine superbly crafted minifigures, some of which include Luke Skywalker, four Snowtroopers, and two AT-AT drivers.

Unsurprisingly, this is not only one of the biggest Lego sets ever but also one of the most expensive, costing slightly under $900. While it’s not everyone’s cup of tea — regarding theme or price(!) — it’s undoubtedly the ultimate Star Wars model to own if you’re a die-hard fan of the legendary sci-fi franchise.  

7. The Lord of the Rings: Rivendell™


Set no: 10316
Pieces: 6167

While we’re on the movie and fantasy theme, next up is one of Lego’s most recent releases, the 2023 The Lord of the Rings: Rivendell Lego set for adults. This exclusive building kit contains 6167 bricks and makes the cut in the top 10 largest Lego sets ever.

Completed layouts measure over 5 inches (39 cm) high, 28.5 inches (72 cm) wide, and 19.5 inches (50 cm) deep. Too large to display as a whole? You can divide this model into three sections: the council ring, the tower, and the gazebo with a river and bridge. It’s the perfect set if building and display versatility is what you’re after.

This set is packed with impeccably designed elements to build and recreate iconic scenes taking place in J. R. R. Tolkien’s mythological Middle-earth world. In addition to features such as Frodo’s bedroom, Elrond’s study, an elven forge, and a stunning Elven house and valley, this set includes 15 minifigures.

And they aren’t your standard minifigures! Instead, these pieces feature detachable legs so you can seat them around the table to recreate the iconic Council of Elrond™ scene! While pricey at almost $500, this is a must-have for any LOTR fan looking for exciting memorabilia and collectible Lego models.

8. Hogwarts™ Castle

Harry Potter Lego sets are some of the most sought-after editions, featuring a stunning catalog of beautifully designed sets for hobbyists of all ages. Hogwarts Castle is the collection’s largest Lego set, standing out for its sublime modular design.

Featuring 6020 pieces, final displays will measure over 22 inches (58cm) high, 27 inches (69cm) wide, and 16 inches (43cm) deep. Unlike most big Lego sets, this one is suitable for fans ages 16+ and is bursting with imaginative elements to recreate classic Harry Potter settings: the Great Hall, Chamber of Secrets, and Whomping Willow.

House banners, moving staircases, benches, and stained glass windows are only a few key features in this set. However, what makes this set particularly exceptional is its total of four minifigures and 24 microfigures!

This modular Lego set is a premium pick to start building up your Harry Potter brick-building collection. Contrary to most sets for AFOLs, this edition offers both play and display potential, making it more dynamic and therefore, suitable across more age groups than most big Lego sets.

It’s the perfect present for anyone wanting to add to their existing Lego stadium collection —  Old Trafford – Manchester United and Camp NOU – FC Barcelona — or interested in experimenting with brick building for the first time. Although a large-scale project, this is a great beginner’s set for adults as it isn’t overly complex.

Where to find and buy retired big Lego sets

Although there are what seems to be an endless amount of Lego sets to choose from, every so often, it’s common to be in a position where the one you really want, well, has been discontinued by the brand.

In the case of the biggest Lego sets, unfortunately, there are a few pretty cool models that are either hard to find or no longer available on the company’s official website — but there are other places to look!

Currently, the most convenient place to purchase retired big Lego sets online is Amazon. We’ve listed the top retired giant Lego sets still available on the online retailer, below.

What to know about the biggest Lego sets

Working through big Lego sets takes your typical brick-building experience to a whole other level. These editions are packed with thousands of pieces to assemble larger-than-life displays, and although there are a few models for young adults, these are all complex sets.

The biggest Lego sets can be found under various themes and categories, whether Lego Art, Lego Creator, Lego Harry Potter, Lego Technic, and others. 

While fascinating to build and gratifying to showcase, there are a few things to know before taking the plunge and purchasing one of the biggest Lego sets ever.  

Whether big Lego sets have more or fewer pieces, they’ve been built with complexity in mind. That said, if you’re taking your first strides into brick building, there are better, easier ways to get started than with a large Lego set.

We advise hobbyists 18+ just starting to explore this creative hobby to look into more straightforward Lego sets for adults first! 

Also, know that there are a variety of themes to choose from when looking into the big Lego sets, from landmarks to sci-fi motifs, movie-inspired models, and historical references: there’s something for everyone. 

If you like a specific theme or subject matter but aren’t quite ready for a hefty investment, whether of cash or time, remember you can also look into smaller Lego sets inspired by the same/similar themes. For example, Lego Architecture sets!

That said, let’s talk about cost. This is one of the greatest deal-breakers regarding the biggest Lego sets because, I’m not going to lie, price tags can get pretty over the top. Therefore, don’t expect to find inexpensive options here: sets are curated for the hardcore Lego fan and longtime collector. 

You can find editions costing anywhere from $200 to over $900. Either way, investing in a giant Lego set will require splashing the cash, so keep this in mind whenever perusing our guide. On the other hand, they sure are worth every penny! 

For more affordable options, we recommend checking out Lego alternatives; there are many quality sets and similar themes to the ones developed by Lego. 

Lastly, it’s important to point out that, like Lego sets for adults, these big models are explicitly designed for display. So, be mindful of your space — even if you have a large Lego table!

That’s it for this comprehensive guide to the biggest Lego sets! Do you have a favorite set, past or present? Let us know in the comments below!
