The Petronas Towers also known as the Petronas twin towers are in Kuala Lumpur, Malaysia.  These were the largest buildings in the world from 1998 to 2004 and remain to be the tallest twin towers in the world.  They are a postmodern Islamic architecture, with elements of religious styles influenced my Roam and Persian architecture but also very modern. You can see the religious style at the top of the towers.  There are 93 floors total, 5 are underground.  This building is made of reinforced concrete with steel and glass façade to resemble Islamic art. Another cool part of this is the cross sections of the towers it is influnced by the Rub el Hizb, a Islamic symbol.  Overall, cool building and very pretty to look at, this kind of reminds me of the Burj Khalifa.
