Add a striking landmark to your Blaustein castle!

Especially large parts (e.g., rock elements), parts in large overall quantities, or special parts (e.g., single studs, double-sloped bricks) are often packed separately. These may be located in different building steps.
There are color differences between the Castle Keep V1 and Blaustein Castle. The Update Kit follows the color scheme of Castle Keep V1. Castle Keep V2, however, includes subdivided building steps and matches the color scheme of the base castle.
