Description

A scene from the Black Lake

The set captures the second Triwizard task, where champions dive into the Hogwarts lake to rescue hostages held by merpeople. Rather than a full building, 76420 focuses on a landscape-style build with rock formations and underwater elements standing in for the lake itself, giving it a different feel from the castle and classroom sets in the same range. At 349 pieces it's a mid-sized build, detailed enough to hold a scene together without demanding a full weekend.

Five minifigures tell the story

Five minifigures make this one of the more populated sets in its piece-count bracket, which fits the scene it's recreating: a task with multiple champions and hostages rather than a single hero. That figure count gives plenty of scope for reenacting the underwater rescue or simply building a varied Harry Potter minifigure collection. For anyone assembling the wider Triwizard or Goblet of Fire story across several sets, this is one of the figure-richest entries.

Sand green and reddish brown set the mood

Sand green dominates the build, giving the lake surroundings a murky, weedy tone rather than the bright colours used in most other Harry Potter sets, while reddish brown adds rock and earth texture around the water's edge. Black grounds the darker underwater areas, and dark blue reads as the lake water itself, completing a palette built specifically for this one scene rather than reused from a generic Hogwarts set.

137 unique parts across the build

With 137 unique parts making up 349 pieces, the set leans heavily on specialised rock, water and foliage elements rather than basic bricks, which matches its landscape-style design and its focus on scenery over structure. The parts list on this page runs through the whole set piece by piece, useful for checking which specific elements create the lake effect, spotting pieces that could work in other outdoor or fantasy builds, or for confirming everything is present if you're buying 76420 second-hand.
