LEGO builder Michał Kaźmierczak found the best place for grey LEGO pieces. He built a huge version of the dwarven fortress Erebor from The Hobbit and The Lord of the Rings series.
The project consumed 55,000 bricks, and it took seven months to complete it. But as you can see the 1.5m tall result is truly awesome.
Bard the Bowman and the dwarves meet in front of the gates of Erebor, right before the battle begins of the five armies begins.
Here's a pic with the creator, just to show how big this set really is.
There's also an interior, and it's just as incredible as the front.
According to the creator, a single dwarf statue weights more than 6kg, and it's bigger than the official LEGO Death Star set.
