*EDIT* I'll need to redo this for 1.13 and beyond to get the included resource pack working. Will do at some point

Santa Maria del Fiore, the cathedral in Florence Italy (and Assassin's Creed 2). I built it in 1:2 scale on a multiplayer server in October 2010, and ever since I have wanted to do it in 1:1 scale.

New for 1.8: the bundled resource pack is applied automatically when you load the world. It also includes old style fences in some places (this build was created before fences attached to blocks, and counts on that behavior in some places), tie rods and statues all of which needed mods before. The textures are an edited version of Steelfeathers' pack. Steelfeathers gets all the credit for the texture pack, and anything that looks bad is probably something I edited.

To play,

1. put the Duomo folder inside the %appdata%.minecraftsaves folder
   
2. If you are using Optifine, Minecraft's auto switching to a resource pack bundled with a world is slightly buggy: the stained glass will not take on the appearance of the custom resource pack. You'll need to copy the resource pack into your resource pack folder and switch to it manually for everything to look right.
   

TODO: modern accurate interior is done, maybe a second version more geared towards Assassin's Creed-like parkour puzzling, and with details appropriate to that era / game (the old choir, chandeliers, old facade maybe). Would love to see it if anyone else makes some better parkour goodness out of this.
