You once built a Lego pirate ship? That's sweet.

Here's something just a little more difficult: A Lego construction that emerges from a flat pack into a 3D Japanese castle.

Posted by YouTube user talapz, the castle is a fairly accurate recreation of a UNESCO heritage-listed building, Himeji-jo, which was built in the early 17th-century and lasts to this day in the Hyogo Prefecture.

According to talapz, the building took 15 months to create and uses no adhesives, which makes the whole thing even more impressive, if true. If you're ready to graduate from the Lego Death Star to something more advanced, consider the gauntlet thrown.
