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 world comes with a bundled resource pack which is applied automatically when you load the world. The textures are an edited version of Steelfeathers' pack and is and distributed with permission from Steelfeathers. Steelfeathers gets all the credit for the texture pack, and anything that looks bad is probably something I edited.
To play,
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.
