This 115-piece building mosaic captures a recognizable castle outline with towers and wall sections that are easy to follow on the color grid. It is a solid mid-size castle build for kids and adults alike.

Rated as medium difficulty with an estimated build time of around 10 minutes, the instructions guide you through the base structure first, then the towers and upper details. The piece count keeps the project engaging without becoming overwhelming.
