Whenever you approach Noord by ferry from Central Amsterdam this striking office building is usually the first thing one notices in the area. Once the tallest building in Amsterdam, it now has to settle for having a beautiful location on the IJ. For more than three decades this was the Dutch headquarters of oil giant Shell, but now it's occupied by a cluster of younger and much smaller enterprises. The Overhoeks Tower and its adjacent pavilion were designed by architect Arthur Staal in 1971. The building is actually for sale for the bargain basement price of only €10 million.
