The user made this replica in a 1/5 scale, in a private Minecraft server. This is his building log:
Idea and Design
The idea for this project came me as I was thinking of my LEGO models, and which ones might be fun to replicate in Minecraft. One such model is indeed the Eiffel Tower (LEGO #10181). Since it is composed mostly of 1x1x1 bricks, I thought I could duplicate it in Minecraft easily just by following the LEGO instructions. However, I found that it is about 110 bricks tall, which would be difficult to build in a Minecraft world. Minecraft allows blocks to be placed up to 64 blocks above and below "sea level," where the world below sea level is almost entirely solid blocks. So while I could laboriously dig down and build a structure up to 128 blocks tall, the bottom half would likely be obscured by surrounding terrain.
I abandoned the idea of basing it on the LEGO model, but the structure still appealed to me because it is has roughly square and symmetrical cross sections along its vertical extent, making it easy to represent with cubes. (Round shapes are harder to faithfully represent.) I decided I would build a replica that sat at sea level, and reach the ceiling, thus being exactly 64 blocks tall. This picture illustrates how I went from the original plans at the Eiffel Tower web site to a set of blocks I could replicate in Minecraft.
The main goal was getting it to look right (form), but a secondary goal was making it accessible in the game (function). To that end, there is a series of internal ladders that you can take all the way to the top floor, and each of the three viewing platforms were adjusted to accommodate players. In particular, in order to support the two-meter player height, the top floor is larger in the model that it otherwise would be.
The Minecraft world I play in is called "Voxelia," which is hosted on a private server with about a dozen players. Voxelia is filled with a number of interesting attractions, many of which are documented in this photo album and these video tours on YouTube. I wanted to build the tower where it would be likely to be seen, ideally near the spawn point where characters first appear. The hard part was finding an area that was also near sea level and that wasn't very obscured, as noted above.
Before I joined the world, a large sand pit near the spawn point had been mined clean in order to make a giant glass dome (another attraction), and this otherwise unused space made for a perfect location.
It should first be noted that this was built without any cheating or automation. Whatever is possible in the unmodified multiplayer alpha "survival" mode is what I used: mining, crafting, and assembly is all done by hand. Due to bugs (or features?) of the multiplayer mode, characters are invulnerable and tools don't get damaged, unlike the single-player mode.
I used a local copy of the world to build a prototype. The prototype was used to validate the design, and only about a quarter of the full tower was built. I originally used cobblestone as the main material. After building the prototype, I decided that steps (half-blocks) would look much better and allow for more subtle adjustments to the shape. However, it would require twice as much stone: two pieces of stone to make a full-size block.
See below for an early construction picture and site maps before and after construction.
Most of the stone was mined from a smooth, vertical pit I developed below the tower plaza. Based on the volume of the pit, I estimate that about 3,000 stone blocks were mined to build the tower.
Last but not least, I decided to call this "L'Effie Tower." (read it backwards)
Thanks for reading! You can reply to the thread at the Minecraft forums if you have any questions or comments about this.
We can all agree that this is the kind of thing that makes us play Minecraft. Make something that makes us proud, with our hard virtual work and an original idea. Seeing such amazing projects gives us inspiration and willpower to start our own. It's great how the Minecraft community keeps surprising us, even after everything we've seen. Congratulations, Mauricio, for your achievement. Keep bringing more of that quality material. :)
