If you played LEGO® when you were a kid, you know how challenging it is to assemble some of the LEGO models that include thousands of pieces. While you may have started building LEGO sets made specifically for kids, you have no doubt advanced into more complex builds just for the fun of it.

If you are anything like us, you have probably brought your love for building LEGO models well into adulthood. We get it, spending hours poring through the pages of the instruction book, and seeing the result of your hard work is one of the best feelings in the world.

Because we love all things LEGO, and are always on the lookout for the next LEGO model release, we compiled this list of the most immersive LEGO models that every adult will want to get their hands on.
