A symbol of engineering prowess, the Capital Gate tower hotel is starting to take form in Abu Dhabi. Designed as the most inclined tower in the world, the 35 storey, gravity-defying feature tower will lean westward 18 degrees, 4 times as far as the Leaning Tower of Pisa which currently leans 3.97 degrees.

Designed by RMJM, the tower relies on a diagrid exoskeleton constructed on top of a 7-foot-deep concrete base to hold the structure in place. 490 piles that have been drilled 100 feet underground will hold the structure still accommodating the gravitational, wind and seismic pressures caused by the lean of the building.
