Watkin's Folly: In 1890s London, British politician and railway tycoon Edward Watkin had a vision to build a gigantic structure that would eclipse the Eiffel Tower. It would stand 1,200 feet above the northwestern suburb of Wembley.

Railway to the sky: Watkins held a contest to design the tower, offering a prize equivalent to $80,000 in today's money. One proposal had a train running up a spiraling railway on the outside of a 2,000-foot-tall tower.

Pyramid power: Another unrealistic proposal had a 1:12 scale replica of the Great Pyramid of Giza on its summit.

The winner: Designed by London architects Stewart, McLaren and Dunn, the winning proposal was similar in structure to the Eiffel Tower, albeit more slender.

First leg: Construction began in 1892, and the first stage -- approximately 150 feet tall -- was finished three years later.

Opened to the public: Once completed and fitted with elevators, the first stage was opened to the public, but there was something wrong with it.

Sinking feeling: It transpired that the tower was starting to subside and any attempts to built it higher, adding to its weight, could have been disastrous.

Shut down: When Watkins died in 1901, so did his grand vision. A year later the tower was declared unsafe and closed down. England's national football and rugby stadium now stands on the same spot.
