LEGO Harry Potter: Mini Hogwarts Castle (40975) on pre-order (August 2026)

LEGO has revealed the Mini Hogwarts Castle, a 700-piece set joining the Harry Potter range at the very end of August. Its release is timed for the start of term at Hogwarts, a date the licence marks every year. The idea is simple: the whole school of witchcraft and wizardry in a single microscale model, mounted on a black display base, for ages 10 and up.

The model brings together the most recognisable parts of the castle: the Great Hall with its tall colonnades, the main tower, the East Wing and the Astronomy Tower, set on rocky ground edged by the water of the lake. Two secrets are built into the structure, which lifts off in sections: the Chamber of Secrets is hidden under the East Wing, and a small concealed room holds the Mirror of Erised. The model measures 5.5 in (14 cm) high and 6.7 in (17 cm) wide, a shelf-friendly size that no previous version of Hogwarts has come this close to.

For characters, the box includes a Harry Potter minifigure in Gryffindor robes, with his wand and a broomstick, plus a large white Hedwig on a transparent stand so she can fly above the towers. The set is due on 29 August 2026 and is already available to pre-order on the LEGO Shop. Availability at partner shops will be announced once it is confirmed.
