In this article, I will list and briefly review my selection of the 18 biggest Lego sets that you can buy. Please note that there are more Lego models that consist of high number of pieces but I have tried to choose something from different Lego categories.

This Lego set was inspired by Star Wars and it was made in cooperation with Disney. With 3,187 Lego pieces, you can build an epic cantina, the hub of underworld activity, which was introduce to the audience in the movie Star Wars: A New Hope. This building kit does not contain only the cantina but also 21 minifigures including the main characters like Luke Skywalker. Han Solo or C-3PO. There are Dewback figure and two Landspeeders inside so you can recreate many scenes.

You can role-play and recreate many of the important scenes – the dark dealings at the bar, action bar scenes, the scene when Han Solo and Greedo met for the last time and much more. I like that the cantina building can be closed and opened so if you close it, you can recreate scenes from the exterior and if you open the building you are able to see the tables and the bar which is perfectly detailed, including glasses or beer tap.

Wrapping Up

Hopefully, this article was helpful for you to choose a large Lego set for you or for your kids. And if you wonder which one I would buy, it would be definitely the Lamborghini Sián model, as Technic is my favorite Lego theme and I love sport cars. However, I’m also a Harry Potter fan, so I would seriously consider the Hogwarts Castle set as well. These big Legos look very nice illuminated with Lego light kits, so you can consider adding one to your purchase, too.
