If the Lego King’s Castle (70404) is just not big or detailed enough then this Blue Lion Castle might be what you are looking for. This classic looking castle is made up of tens of thousands of Lego pieces. The whole things sticks to a gray and blue color scheme that works extremely well. These Lion Knights and Soldiers are protecting one of the most epic Lego castles ever built. The detailing in the walls, the stained glass, the grand entrance, and the huge tower make this thing a work of art.
The Lego Blue Lion Castle was inspired by the famous Hohenzollern Castle. Which is located on the top of Berg (Mount) Hohenzollern in Germany. The iconic Hohenzollern Castle shares the blue and gray design, and overall floor plan with the Blue Lion Castle. The Lego version though seems to be much more ornate then the real life inspiration.
