For the past two years, LEGO has been working on its most ambitious project yet: a minifigure-scale model of Hogwarts Castle, made iconic by the Harry Potter series. The castle remains under construction and will eventually comprise a series of individual, interconnectable sets sold separately. The first major release, the Great Hall, launched in Fall 2024.
Hogwarts Castle: The Main Tower

The Main Tower, now available, is the second core set in this modular system. It joins a range of separate ancillary buildings and classrooms like Hogwarts Castle: Potions Class (Set #76431), Hogwarts Castle Owlery (Set #76430), Hogwarts Castle: Flying Lessons (Set #76447), and Hogwarts Castle Boathouse (Set #76426).
Nevertheless, the Main Tower also functions perfectly as a standalone playset, particularly for fans of the first book and film, Harry Potter and the Sorcerer's Stone.

Mirroring the Great Hall, the Main Tower's rear opens to reveal multiple rooms and dioramas depicting key movie moments. The lowest level, built first, features the underground chambers guarding the Sorcerer's Stone. From left to right, you'll find the Devil's Snare room, the Flying Keys chamber, and the giant Wizard's Chess board room.
Each room includes interactive, movable features. The Devil's Snare flips up or down from the ceiling via a cleverly concealed switch in the rock wall. The Flying Keys spin on a pedestal to simulate flight. The oversized chess pieces are fully independent and can be repositioned.
The set includes LEGO minifigures of Harry, Hermione, and Ron—essential for bringing these scenes to life as the trio interacts with the environments. This section prioritizes specific book accuracy over open-ended play; each room recreates a particular scene rather than serving as a generic role-play space. Beyond the trio, nine additional minifigures bring the total to twelve: Neville Longbottom, Dean Thomas, Marcus Flint, Percy Weasley, Ernie Macmillan, Lisa Turpin, Professor Dumbledore, Professor Kettleburn, and Nearly Headless Nick.
Directly above the Devil's Snare room lurks Fluffy, Hagrid's three-headed dog, guarding a trapdoor that leads to the chambers below. In the room's rear-right corner sits a harp, which Professor Quirrell uses to lull Fluffy to sleep. The harp's design is particularly inventive, with two separate builds joined by hinges to form the instrument's distinctive shape. A door on the right opens to a narrow hallway, which leads outside to a balcony offering an exterior view.
Above Fluffy's room is the Gryffindor common room, adorned in its signature scarlet and gold. It features a bedroom with two beds and, to the right, two armchairs beside a fireplace. The living area floor is sunken, creating a cozy, intimate nook.
These individual rooms are separate builds with their own instruction booklets. This allows for collaborative building—with a partner, friend, or as a parent-child team—as the completed modules easily connect. They stack via several connection points, remaining simple to detach. This modularity provides more space for posing scenes or playing with components individually. While sets of this complexity are often rated 18+, the Main Tower and related Hogwarts Castle sets are 10+, striking a better balance between play and display.
After capping these sections with a roof, you construct the Main Tower proper, stacking five rooms vertically. The first three floors house Hogwarts' iconic moving staircases, devised by Rowena Ravenclaw. Two staircases are on rotating platforms, allowing them to swivel. Walls are lined with portraits. The third floor features a guardian gargoyle for the hidden entrance to Professor Dumbledore's office.
That office occupies the fourth floor, crowded with portraits of past Headmasters and various magical curiosities seen in the films. To the right of Dumbledore's desk are the Sword of Godric Gryffindor and the Pensieve. To the left sits the Sorting Hat, complete with a mouth near its brim. Dumbledore's office is arguably the set's highlight, beautifully furnished and perfect for recreating Harry's evening lessons with the Headmaster.
Finally, you build the massive spire that crowns the tower. Inside is the fifth and topmost room, containing the Mirror of Erised. The mirror is on a rotating stand, letting you switch between two backed images: one showing Harry with his parents, the other showing him holding the Sorcerer's Stone.
The Main Tower's scale is striking, standing over two feet tall from the base rockwork to the spire's peak. Combined with the Great Hall, it's even more impressive, forming a seamless exterior. The combined interiors create a sensory overload of iconic Hogwarts scenes condensed into a relatively compact space.
Ultimately, there's little more to say except this: I want to see more. The last time LEGO created a massive Hogwarts Castle, it felt somewhat piecemeal, with no official assembly guide, leaving fans to puzzle it together from promotional images.
This time feels different. There seems to be a master plan; I strongly suspect a "complete" Hogwarts Castle exists somewhere at LEGO, whether physically or digitally. The designers aren't improvising—they are working toward a definitive final vision.
It will take years to complete. But if LEGO maintains this meticulous detail and sees the project through? It will be an unparalleled achievement. To be continued.
LEGO Hogwarts Castle: The Main Tower, Set #76454, has a retail price of $259.99 and contains 2,135 pieces. It is available now.
