LEGO Harry Potter 6644876 Micro Castle

LEGO set 6644876 Micro Castle, released in 2026 as part of the Harry Potter line, has 43 pieces. Its inventory breaks down into 16 different lots, across 6 colors.

Micro Castle sits within the Harry Potter theme as a small architectural interpretation of a castle associated with the license.

The build is therefore centered on brick-built forms that suggest a castle at a reduced scale.

This set is suited to Harry Potter collectors who want a small display item for an existing shelf or themed arrangement. It can also work as a modest companion piece alongside other sets from the same theme. Within the wider range, its defining points are the micro format and the absence of minifigures, which separate it from sets built around scenes and character interaction.
