This is the custom made crane that they use to lift the blocks. It was unfortunately impossible to get it up any way but by hand - i.e. they carried it, piece by piece, all the way to the temple and had to put it together it manually.
Here you see the north side where most of the work is going on right now. They estimate that they'll need another 50 years [sic] to finish the work.
