Lego Architecture – Eiffel Tower (21019) Review


Lego Architecture – Eiffel Tower (21019): Well I wouldn’t be properly back from a summer hiatus without doing another architecture set, and this time we go to Paris. This is without a doubt though the largest of the Architecture line that I’ve done so far. Also despite the intentional Leaning Tower of Pisa or the thinly Space Needle, this feels the most ‘unsecure’ due to it’s unique design which works great visually (and is a joy for those who love sub-assemblies), but lacks rigidity.

What Else? France as you may know was not originally pleased with Eiffel, and the ugly sculpture he placed upon the city. It was considered an unattractive iron latticework that would never be viewed as more than an industrial mess. Of course we know minds and hearts changes, but personally I’ve always loved Ironwork sculptures, and considering the size of this rather large architecture set I wanted to see how impractical an iron version would be at this scale.

So first the density of Wrought Iron is 7750 (kg/m3) whereas ABS plastic used in Lego is a measly 1.07 (g/m3). Now since we’ve already got the weight (which with no force gives us mass) we get an actual volume of 184.11 cm³ instead of the 321 above (because Lego’s are not exactly solid.)

Putting that into our p = M/V function we get an answer of 1426.86g which for those wondering is actually only a measure of 3.14 pounds. Now while that’s not absurd, it certainly makes one hell of a paper weight for your bookshelf.

In fact it’s about 240% stronger. Since our mini wrought-iron tower is about 50.25 oz, and despite there not being a study I could find about the average size of paper weights – Amazon is kind enough to help with a range. Most paperweights seem to fall between 6 and 25 ounces from the first page of results (I don’t count this 2.4 pound behemoth though) but we get an average of 14.75 oz, and hence our mini-Eiffel Tower is a 240% better paperweight than most of what you can get on Amazon


Remix: So for this weeks remix I took a bit longer than I normally do – mostly because I knew I wanted a Lunar/Planet lander, but because getting the scale was difficult. This lead to what is far away the weakest (structurally speaking) set I’ve made. There was no way adding 5 pieces would have helped (I did manage to use all the pieces though) so I simply did the best I can – and while I’m pleased with the looks, a simple table bump can destroy this.



Final Thoughts: Due to it’s size I feel like if you had to choose only 1 set of the line for your bookcase – you would still not pick this. In part because it’s height would simply not fit, but mostly because while the set is certainly visually interesting – it takes up a certain presence, and makes you wonder that maybe if the design was a bit simpler the scale could be a more manageable size, and whether such a tradeoff would be a good idea.

Final Score: 3 out of 5 Stars
