Lego Architecture – The Leaning Tower of Pisa (21015) Review


Lego Architecture – The Leaning Tower of Pisa (21015): Well here goes this crazy review thing. I couldn’t think to start with a better model though. I’ve always been a fan of the Lego Architecture series, and I’m a bit surprised by the Tower of Pisa model. Partly for how sturdy it actually is (haha bad jokes), but on how much it’s a great size to capture it’s essence. Any bigger and it’d feel off trying to replicate, and smaller just couldn’t give you the details as effectively, anyway onto the build.


Time to Knoll: 13 Minutes


Time to Build: 28 Minutes




  • Pieces: 345 and 65 Steps – Manual
  • Price: $34.99 on Lego and $31.26 on Amazon
  • Volume (Based on Blob length/width/height): 64mm x 96mm x 89.6mm or 550.5 cm³




  • Uniqueness: 5 out of 5 Stars
  • Aesthetics: 4.5 out of 5 Stars
  • Fun to Build: 2.5 out of 5 Stars
  • Hoarding: 3 out of 5 Stars


What Else?

So then looking into the dimensions of the Leaning Tower of Pisa from here and here, we can see that the outer diameter is 15.484m, and the inner diameter is 7.368m. Then based on the height (including foundation) of 58.36m (of which I’ve assumed the wall height to be akin to the ceiling height) we get an outer volume of 10,989.3m3 and an inner volume 2,315.29m3 of giving us a total volume of ~8,674.01m3

From there we have this. Which gives us that to recreate the real leaning tower with the sets of just this Lego set would be about ~15,757,000. Which in truth 15.7 million isn’t actually that much. However this doesn’t account for structural needs, and note there are a lot of flat-top pieces of which there would be a lot of need, but likely not this much.

Anyway I made a mountainside processing plant for something like chemicals and such. Keeping with the remix rules (see About page) I added nothing to this build, and actually only kept out the single piece with the name.





Final Thoughts: Overall I’m happy signing up for the Pley service because while I like sets like this, I don’t see this as something I’d like to buy and keep around (there’s a lot of other architectural sites I’d rather have), but it’s a neat build.

Final Score: 3 out of 5 Stars
