The Taj Mahal in Agra India, including the grounds/garden, the gatehouse, guest house, mosque, and some side buildings.

This was built on the Shacknews multiplayer server and involved punching thousands of sheep. It's done at 2/3d scale. 1:1 would fit between sea level and skybox if it wasn't for the elevated platform the taj sits on. If I were to do it today, I'd MCedit a world with enough height, but oh well.

Not done (and who knows if it will be) as the gardens need some vegetation, the taj needs some more work on the outside (some woodwork in the arches) and possibly the interior

The schematics attached are cleaned up from the world it was built in (no sky canal in the background, corner where someone else had a building filled in) There are two versions, an all in one schematic and a split up version (paste them all from the same place). The split version is because my minecraft+worldedit chokes on the all in one, but the all in one is probably usable with MCEdit
