Description

A lighthouse with two faces

Hidden Side sets were known for giving many builds a normal look and a haunted one, and The Lighthouse of Darkness follows that same idea with a tower that feels threatening and abandoned. With 548 pieces and 223 unique elements, it's one of the more detailed builds in the range, shown in the many small structural and decorative pieces that give the tower its distinctive, slightly morbid look. Anyone who prefers building a structure with a backstory rather than a simple vehicle will find an unusual subject here.

Five minifigures for a chase

Five minifigures leave plenty of room for small stories involving ghost hunters and the supernatural opponents Hidden Side was known for. That means both the human characters and several enemy figures can be used at once, rather than leaving one side of the story out. In a horror theme like this, the number of figures makes a real difference, since it allows genuine chases and confrontations around the lighthouse to be acted out.

Greys, detail and the parts list

The light bluish grey, dark bluish grey, white and black palette deliberately creates a stark, slightly eerie stone look that suits the night-time setting and stands out clearly from the bright colours of more conventional themes. The parts list on this page details exactly which of the 223 unique pieces were used, which is especially helpful for a now-discontinued theme like Hidden Side, where individual pieces can be hard to source for repairs or custom builds.

A model for collectors of retired sets

Since Hidden Side was retired after only a few years, The Lighthouse of Darkness now counts among the sets no longer sold new, which adds to its appeal for collectors. The high count of 223 unique pieces also makes it interesting beyond the theme itself, as a source of parts for other custom horror builds or dark-toned structures. For anyone who already owns the set, the parts list here is a solid reference for tracking down missing or damaged pieces.
