10 Largest LEGO Sets Available for Purchase in 2025

LEGO sets with high piece counts often come with hefty price tags. Historically, LEGO pricing averaged around 10 cents per brick, so a 5,000-piece set typically cost about $500. However, modern pricing varies due to factors like third-party partnerships (e.g., Disney), which can increase costs, or the use of common pieces, which may lower them.

While this list shares some entries with our roundup of the priciest LEGO sets, it’s not identical. Below, in ascending order of piece count, are the 10 largest LEGO sets available for purchase. We’ll keep this list updated, but it may be some time before a set surpasses 10,000 pieces.

Harry Potter: Diagon Alley

LEGO Harry Potter: Diagon Alley

The LEGO Harry Potter partnership is exceptionally rich. Like the expansive Hogwarts Castle, Diagon Alley can be built by collecting multiple sets. This set kickstarts the journey with four large buildings housing seven iconic shops: Ollivanders Wand Shop, Scribbulus Writing Implements, Quality Quidditch Supplies, Florean Fortescue’s Ice Cream Parlor, Flourish & Blotts, Weasleys’ Wizard Wheezes, and the Daily Prophet.

Harry Potter: Hogwarts Castle

This microfigure-scale Hogwarts Castle stands over two feet tall and nearly two feet wide. Launched in 2018, it remains a staple despite its age in LEGO terms. It includes 27 microfigures and full-size minifigures of the Hogwarts Founders: Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw, and Salazar Slytherin, delighting Harry Potter enthusiasts.

Ninjago: City Markets

LEGO Ninjago: City Markets

LEGO Ninjago fans can dive into the bustling City Markets, packed with 22 minifigures and vibrant urban energy. Unlike the nostalgic modular buildings, this set captures a crowded cityscape. Across four floors, you can enjoy karaoke, savor sushi, ride a cable car, shop for sweets, or play pool in a lively half-block.

The Lord of the Rings: Rivendell

LEGO The Lord of the Rings: Rivendell

Rivendell stands out as one of the largest and most beautifully designed LEGO sets for adults. Its delicate elven architecture, from the iconic gazebo to the Council of Elrond, feels almost ethereal.

Star Wars: Razor Crest

Though destroyed in The Mandalorian’s second season, the Razor Crest remains an iconic starship from the post-Lucas Star Wars era. With a Mandalorian movie on the horizon, its popularity endures. The set includes a carbonite freezing chamber, weapons cabinet, and escape pod, all in minifigure scale.

Star Wars: Millennium Falcon

LEGO Star Wars: Millennium Falcon

Available since 2017, the Millennium Falcon is a timeless LEGO set, proving its appeal among adult collectors. Nearly three feet long and two feet wide, it mounts on a stand for a dynamic ‘flying’ display, cementing its status as a landmark in LEGO’s adult-focused offerings.

Titanic

Eiffel Tower

LEGO Eiffel Tower

With 10,001 pieces, the LEGO Eiffel Tower is the largest set by piece count in LEGO’s history, surpassing the retired 9,036-piece Roman Colosseum. Nearly five feet tall, it features observation decks and cable-operated elevators, offering remarkable value at $629.99.

How to Find Discounts on LEGO Sets

High piece counts often mean high prices. So, how can you score these massive LEGO sets at a lower cost?

Join the LEGO Insiders program to earn points on every LEGO Store purchase, which can be redeemed for discounts on pricey sets. Look out for promotions like Star Wars Day, which often double your points on select sets.

Additionally, browse retailers like Amazon, Walmart, Target, or Barnes & Noble. Surplus inventory, especially for retiring sets, often leads to discounts. Events like Amazon Prime Days can also offer significant savings on sets typically sold at full price.
