a reproduction of Michelangelo's Sistine Chapel:

Strolling past the opulent corridors of faux frescoes and through the clanging action of the Venetian's casino prepares you for a rather breathtaking encounter with the Guggenheim Las Vegas - a gargantuan, 64,000-square-foot, 70-foot-high, "Big Box" museum with a reproduction of Michelangelo's Sistine Chapel painting on the translucent ceiling.

So, is the answer, the Guggenheim at the Venetian (not the Guggenheim Hermitage)?
