70437

LEGO set 70437, Mystery Castle, depicts a haunted castle within the Hidden Side theme. Released in 2020, it includes 1035 pieces and belongs to the theme’s paranormal setting, where physical building is paired with ghost themed storytelling.

Mystery Castle is a prominent location based model in Hidden Side. Rather than focusing on a vehicle or a small urban scene, it presents a haunted fortress that suits the theme’s ghost hunting stories, supernatural opponents and eerie locations.

The set contains 1035 pieces and 5 named minifigures: Parker L. Jackson, Jack Davids, Shadow Walker with Helmet, Nehmaar Reem and Vaughn Geist. The build is centred on a castle silhouette, with areas for character placement and play scenes. The confirmed information supports a general description of the model’s haunted setting, figures and theme identity, without adding unverified mechanical details.

It is relevant to Hidden Side collectors looking for a central display setting, and to builders who prefer fantasy architecture with a darker tone. Within the theme, it stands out through its castle subject and through the mix of heroes, antagonists and spectral figures gathered in one location.
