Petronas Twin Tower Description
The design of the floor-plate of the building is being based on geometric patterns that are very common in the Islamic heritage architecture. It is made up of two rotated and overlaid squares with small spherical infills. The architects of the building described these geometric patterns to be a symbol of harmony, unity, rationality, and stability. All of these virtues are significant in the principles of Islam belief.
