Angkor Wat 19
Himeji Castle 18 - 3 = 15 (I am surprised this castle made it thus far. While the castle is known for its story of a legendary defense, there's nothing about this structure that screams world wonder to me. It is similar to many other castles, including Osaka castle and other samurai castles. As such, it is not quite as unique as the other two rival wonders.)
Taj Mahal 27 + 1 = 28 (Sorry, but this is either the best one remaining, or Angkor Wat is, both in terms of size and unique story. But I'm a bit of a romantic so I'll go with the Taj in this case)
