We all have fond memories from our younger years putting together fun LEGO sets like cars, planes, houses, and more. But if you were especially lucky (or especially wealthy), you might have had the opportunity to construct truly massive LEGO sets like the Taj Majal, Shield Helicarrier, or even the fabled Death Star Itself.

#11: SHIELD Helicarrier

Pieces: 2996

MSRP: $349.99

See the SHIELD Helicarrier on Amazon

Below are the 11 biggest pre-made sets the LEGO company has ever released, sorted by number of pieces. We've included Amazon links if you want to check out any set further, but keep in mind that most are either intended to be Lego.com exclusives or are out-of-print, so don't expect to nab them for their MSRP. All data in this list was pulled from independent LEGO site Brickset.com

#10: Imperial Star Destroyer

Pieces: 3096

MSRP: $2,649

See the Imperial Star Destroyer on Amazon

For the ultimate Marvel Cinematic Universe fan, the Shield Helicarrier comes with five Avengers minifigures, a big bunch of manofigures, and functioning turbines powered by AAA batteries with a special add-on. Along with a few thousand other tiny details.

#9: Super Star Destroyer

Pieces: 3152

MSRP: $130

See the Super Star Destroyer on Amazon

The Ultimate Collector Series version of the Imperial Star Destroyer is full of interior detail that doesn't actually show up when the entire beast is assembled. But the most impressive thing about this set is its sheer size - it's over three feet long! Long out of production, it now routinely sells for over $2,000.

#8: Grand Carousel

Pieces: 3263

MSRP: $249.99

See The Grand Carousel on Amazon

Did we say the Imperial Star Destroyer was big? If you want to build this Super Star Destroyer, you're going to need an even bigger table - this massive model is more than four feet long when fully assembled. Its custom minifigs are a nice touch.

#7: Sandcrawler

Pieces: 3296

MSRP: $299.99

See the LEGO Star Wars Sandcrawler on Amazon

The Grand Carousel is an epic set for its detail, not for its sheer size. Its complex, colorful, and is (of course) fully motorized.

#6: Eiffel Tower

Pieces: 3428

MSRP: $199.99

See The LEGO Eiffel Tower on Amazon

If you're a big Star Wars fan, these probably are the droid you're looking for. In addition to several fun droid minifigs (Gonk Droid!), this 2014 version of the Sandcrawler model comes with functioning treads, and of course a ridiculous amount of internal detail. It's also got nearly twice as many pieces as the original 2005 UCS edition.

#5: Death Star II

Pieces: 3441

MSRP: $269.99

See the Death Star II on Amazon

After its fully assembled, this Eiffel Tower stands over four feet tall! It's a challenging build, making it perfect for LEGO pros. Newbies might want to pick a set that isn't almost all grey pieces.

#4: Death Star

Pieces: 3803

MSRP: $399.99

See The LEGO Death Star on Amazon

The Death Star II, like every model on this list, is absolutely massive, of course. But it includes a lot of neat smaller details, too. I'm especially found of the physical lasers.

#3: Tower Bridge

Pieces: 4287

MSRP: $239.99

See Tower Bridge on Amazon

LEGO's 2008 Death Star is a different kind of LEGO set. Plenty of these massive models have interior detail, but it's usually hidden away. This Death Star takes a diorama approach, allowing you to see lots of movie scenes all in one model. This set is rumored to end its long run and go out of production soon.

#2: Ultimate Collector's Edition Millennium Falcon

Some hardcore LEGO fans dislike the Tower Bridge build since you basically have to build the same tower twice, but it's still a hugely impressive and aesthetically pleasing model.

#1: Taj Majal

Pieces: 5922

MSRP: $399.99

See the Taj Mahal on Amazon

What is there left to say about the Ultimate Collector's Millennium Falcon? It's just plain awesome, all-around. Fantastic build experience, epic scope, nice minifigs, and great detail. If you didn't snag one when it came out in 2007, expect to shell out as much as $6,000 to buy it in-box now. Reprint, please!

LEGO's Taj Mahal set clocks in at almost 6,000 pieces, making it the biggest individual LEGO set ever made. The finished model is over 20 inches wide and over 16 inches tall, making it an imposing model to say the least.
