The Gate of the Capital is a complex of hotels and offices. Not only has 4 times the slope of the Leaning Tower of Pisa, but also has a soft curve, giving a strong visual impact and enjoyment. In order to make the design feasible in the structure, the core of the building is inclined in the opposite direction, and the more straight to the top. It is based on 7 layers of concrete and is reinforced with dense mesh reinforcement. There are also 490 100-foot-deep piles to withstand gravity, wind and earthquake forces. It is one of the landscapes on Abu Dhabi's postcard.
