LEGO set 21137, The Mountain Cave, represents a large rocky and underground Minecraft scene within the Minecraft theme. Released in 2017, it contains 2863 pieces and brings together a selection of characters and creatures from the game.

The Mountain Cave belongs to the LEGO Minecraft range, which translates the game’s block based visual language into physical construction. Its subject is a mountain and cave environment, presented as a broad setting rather than a single standalone structure.

This selection combines player characters, hostile mobs and the kind of setting associated with exploration in Minecraft.

It is suited to builders who want a substantial Minecraft display piece as well as a basis for role play. Within the theme, it sits among sets focused on caves, mining and encounters with creatures, making it a clear environment based entry in a Minecraft collection.
