The whole thing is just a hair over six and a half feet tall and made from over 50,000 bricks. That black box at the center (where half of the castle rests) makes it easier to transport and show off at different shows.
This is the work of Steve Price, who converted the entire battlestation to a peaceful palace using LEGO Friends pieces. The whole thing includes a pizza room, a dancefloor, salon, juice bar, and concert venue. And obviously that giant death ray has been converted to spread friendship and happiness around the universe. Because duh.
