At the end of the twentieth century, race to build the tallest buildings in the world reached its peak. American buildings started to “give up“, and most world projects were planned in Europe and Asia. Petronas Towers or Malaysia’s Twin, as many call them, are still the highest commercial-residential buildings in the world. They are 452 meters high and their construction was completed in 1988. Both towers have 88 floors. They consist mainly of various metals and glass. At 41st and 42nd floor these building are connected by “air floor”. Petronas towers are located in the capital of Malaysia, Kuala Lumpur. The center of the city is the so-called “golden triangle” dominated by tall buildings and among them, these two huge buildings attract the most attention. They are designed by the architect Cesar Peli, who designed several large constructions projects such as buildings, airport terminals and bridges. Towers project was based on traditional Malaysian-Islamic cultural elements.
