De Rotterdam is a three high rise building complex located by the river bank at the heart of the city downtown. The three buildings are all connected in the base but they are shifted a bit to each other in upper floors which make the look quite amazing. This ultra-modern landmark of the city of Rotterdam was designed by Rem Koolhaas. While the look of the shifted tall towers is amazing, what is even more amazing is such shifted design of tall towers enhances stability of the buildings against wind. Added perk is to provide terraces in high rise buildings. It is quite fascinating buildings and one of the most impressive that I have seen in my life.
