Architecture can be used to communicate wealth or power. An example in the history of The Netherlands are the canal houses in Amsterdam. A more modern ‘show off’ of wealth is the ING House on the A10 in Amsterdam. A rather small Head Office on a very expensive piece of land. And building high risings is another example where (not only) Dutch cities build literally their image and show off economic power. This is Delftse Poort, til 2009 the highest building in The Netherlands. The five highest buildings in The Netherlands are all in Rotterdam (this is the ranking).
