LEGO sets come in just about every shape, size and licensed theme you can dream up. But some sets stand out for their sheer enormity. Not only are they impressive to display, but they've also got a lot of bricks if you're up for the challenge. Anyone can do them, but they tend to gravitate towards LEGO collectors eager to take on the task of building sets of up to 10,000 individual pieces.

Unfortunately, the biggest LEGO set ever made — the Art World Map — is retired, but you may get lucky and find it on the resale market in limited stock. But other crazy large sets, like a nearly 5-foot-tall Eiffel Tower, are still sold by LEGO.

Note that since most LEGO pricing is pretty much based on the amount of pieces (and other special features, like minifigures), these tend to be a bit pricey. But if you want a good challenge or set to impress, these large builds would make a standout gift or family project you can work on together.

LEGO Eiffel Tower

Eiffel Tower

The largest set currently available, and the tallest set LEGO has ever made, this replica stands at 4 feet and 11 inches tall when completed. It's built in four sections that snap together, and there is an esplanade underneath with trees and lamps, to make it feel like the real deal.

It's a limited item, so it's often on backorder, but you can still pre-order one now that will ship when it returns to stock.

LEGO Disney Castle

Disney Castle

Nothing can quite capture the feeling of walking into a Disney Park and seeing the castle, but this almost 3-foot-tall castle can give you a little bit of the magic when you walk into your house. This Princess-filled dream comes with Tiana, Cinderella, Snow White and Rapunzel and their significant others. And there are magical fireworks that jut out of the building for a little extra sparkle.

LEGO Titanic

Titanic

At over 4 feet long, this ship features all of the elements that make it so famous. Once finished, it opens into three sections so you can see inside to the boiler room and grand staircase. The pistons even have a button to make the propellers turn. It's a 1:200 scale ship model of the vessel that set sail on that fateful night in 1912. Jack and Rose are not included.

LEGO has made some pretty spectacular Star Wars sets over the decades, but none more magnificent than this nearly 8,000-piece Millennium Falcon. The ship that made the Kessel Run in less than twelve parsecs is fully realized, and can be configured to showcase the classic and recent crews.

This set comes with minifigures of Han Solo, Chewbacca, Princess Leia and C-3PO, along with an older Han Solo, Rey and Finn. The set also has a buildable BB-8, Mynock and several Porgs, so you can reenact scenes on the fastest hunk of junk in the galaxy.

    This might not look that big, but at over 6,000 pieces, this is an impressively accurate build of The Mandalorian ship. The model has side hatches that open and cargo storage, along with a cockpit where the minifigures of Mando and Grogu can hang out. It's over 2 feet long, and in addition to the two minifigures, also the Mythrol, Kuiil and a Blurrg are included.

    LEGO 'The Lord of the Rings' Rivendell

    'The Lord of the Rings' Rivendell

    I'm an avid LEGO builder and have put together some large sets, and this is one of most challenging I've attempted. The level of detail is truly unmatched, because you feel like you are building Rivendell with a colorful tile roof, a gazebo and delicate trees. Other standout features include statues on the outside of the tower and the table with all the fellowship. Plus it comes with 15 minifigures to really make the movie scenes a reality.

    • Dimensions: 16" x 29" x 20"
    • Pieces: 6,167

    LEGO 'Harry Potter' Gringotts Wizarding Bank

    'Harry Potter' Gringotts Wizarding Bank

    While the Hogwarts Castle may be the most distinctive silhouette in the Harry Potter universe, Gringotts with it's watchful dragon is probably a close second. The bank stands on a platform that looks precariously balanced (but is surprisingly sturdy) so you can see the vault beneath. You can put Hagrid and Harry in a cart that moves down a spiral track.

    • Dimensions: 32" x 13" x 10"

    LEGO NINJAGO City Workshops

    NINJAGO City Workshops

NINJAGO is a LEGO-themed and corresponding TV series, and this playset comes with 10 minifigures and a buildable mech figure that can be placed about this four-story apartment complex. It includes moving elements like working cranes and individual stores and apartments for acting out favorite scenes and battles.

    One does not simply walk into Mordor, but one could build the dark tower that looms over Middle Earth. The Eye of Sauron stands at the top of the nearly 3-foot structure, and it comes with a light brick to give it an eerie glow. An automated black gate opens and closes, and inside the structure there is a throne room, prison and weapons forge.

    LEGO NASA Artemis Space Launch System

    NASA Artemis Space Launch System

This isn't just the Artemis rocket or Orion capsule, but both, and also includes the retractable launch tower. Completed, it stands an impressive 27.5 inches tall, and has a separate stand for display.

    Our Senior Parenting Editor Marisa LaScala had a great time putting this set together with her family. "It’s full of great little details, like different objects and accessories that belong to the different X-Men," she says. "My husband and 9-year-old enjoyed figuring out who owned the boom box, the bubble gum or the issue of the X-Men comic that came with the set."

    She adds that once the set was built, "It has all these fun touches, like a dome that pops off so you can pretend a Sentinal destroyed it. It also comes with a TON of minifigures and pieces that make them look like they’re flying or using powers."

    • Dimensions: 11" x 16" x 10"
    • Pieces: 3,093
    • Minifigures: 10
