North Korea's vast Ryugyong Hotel not opening yet after all
Il Labirinto Stra, Italy Outside Venice. Labyrinth of the Villa Pisani, created in 1720, has a rep for being the most difficult in the world to solve. Even Napoleon was floored by the challenge. The hedges are too high for anyone to peek over. You get a perfect view only once you’ve figured your way through to the center and ascended a spiral staircase to a turret. Fight your way out again to enjoy the beautiful 18th century palazzo overlooking a canal.
