Amazing structures that remain a dream

The world is dotted with amazing structures, but some projects have failed to become a reality.

Here we take a look at structures that have remained a dream, according to Business Insider.

The Chicago Spire

Chicago, Illinois, United States

With only the foundation work completed, the construction to build the 2,000-foot skyscraper was halted in 2008 because of the recession.

After its initial financing problems and a few re-designs, the project was officially axed.

The Illinois/Mile High

Chicago, Illinois, United States

In 1956, Frank Lloyd Wright envisioned a skyscraper that would shoot a mile-high into the sky. The conception of the building would have vastly expanded the urban sprawl of Chicago, but the project was never truly financially achievable.

The Illinois was never built.

Nakheel Harbour and Tower

Dubai, United Arab Emirates

The Nakheel Harbour and Tower project had ambitions to serve as the new, unofficial capital of Dubai. The tower's plans would have made it the tallest structure in the world at nearly 4,600 feet.

As the world had an economic downturn in the 2000s, by January 2009 the project was put on hold, and 18 months later cancelled.

The Russia Tower

Moscow, Russia

The Russia Tower remains partially built in the Moscow International Business Centre. The project began in 2007 and was scheduled to be completed in 2011.

The credit crisis of 2008 hindered the developer from securing finances for the building. It was officially cancelled in June 2009.

Shimizu Mega-City Pyramid

Tokyo Bay, Japan

This planned structure was a huge pyramid that would just sit over Tokyo Bay. This pyramid would have been 14 times higher than the Great Pyramid at Giza.

The project was doomed from the start because the materials needed to build the structure have yet to be invented.

...

Tatlin's Tower

St Petersburg, Russia

Vladmir Tatlin designed Tatlin's Tower in 1919, intending it to be a Utopian project that dwarfed the Eiffel Tower. The structure would be made from iron, glass and steel. Vladmir Tatlin also wanted the tower to be rotated once a year.

The structure would have served for conferences, lectures and legislative meetings, but it was never built.

Fourth Grace

Liverpool, England

The project's namesake comes from the location of three historic buildings in the Pier Head site in Liverpool, which are known as "The Three Graces".

Difficulties plagued the project from Day 1 and costs began to escalate. Fourth Grace was cancelled in 2004 and since has been relocated to Toronto, Canada, where construction is slowly under way.
