(CNN) -- Gaze across the Riyadh skyline and one building immediately demands your attention. Towering high above the city, with its distinctive inverted arch, is the 992 ft Kingdom Center -- owned by the richest man in Saudi Arabia, if not the Middle East. Prince Alwaleed Bin Talal Al Saud's wealth has been estimated at anywhere between just over $20 billion by Forbes and more than $30 billion by Bloomberg. Whichever way you look at it, it's a lot of money -- could it be set to grow? Inside His Majesty's striking skyscraper is the headquarters of Kingdom Holding, one of the largest investment companies on the country's stock exchange.
