This tower is (loosely) inspired by Dante's Divine Comedy trilogy, specifically purgatorio. In the original poem, purgatory is envisioned as terraces on a mountain, where people not yet good enough for heaven have to overcome their sins. In the poem, there are terraces for the 7 deadly sins, 2 for special cases, and the garden of eden, making 10.

I liked the idea of a spiral tower that reduces in width over time, like many pictures of the mountain. My tower might have sections named after each of the sins, but the purgatory theme is not necessary to the build. The coloured sections are where it increases, at a rate of half. Gray is the wall, light gray is for the flat parts around corners. The top part is considered the 7th layer. Yellow represents doors into the separate sections. From the interior, different sections will be isolated from one another. If you want to go from the bottom to the middle, you have to go outside and around the tower. Sections can occupy multiple floors, since the bottom sections are pretty tall.

The total height is 180 blocks (that means you can build it starting at sea level and have about 10 blocks to spare). Width and length of the tower are 45 (through the middle).
Anyone can use the picture and this description to build it for themselves. I'll be posting progress with the project as time goes on.

For now, this project is going to happen in creative, because it's pretty huge, and I want to be able to show everyone pregress quickly. That said, I do hope to create it in survival one day.
