Report about AmsterdamAmsterdam's houses are built above waterproof foundations so this way the houses don't sink in the mud.

The actual railway station in Amsterdam is a vital center and it is built above 9.000 foundations in an artificial island but centuries ago there was a harbour over there.The city was inside of a sea and its harbour gave a lot of richness but the harbour wasn't deep enough and because of this they always had to keep it open.

It is always cold but during the night they cool the water and there is a competition about swimming through the channels. Even the queen has participated!

Amsterdam has three bridges that make a belt and beside the bridges there are three types of houses:1-Houses for rich people2-Houses for middle class people3-Houses for poor peopleAnyway the houses for rich people were built with stones to make them look bigger and fancier. But nowadays the houses are very expensives and most of the buildings are banks or business.

There is an extension project which consists in add three channels and this way we can count more than 100km of channels in Amsterdam. People call it as "Venice of the North". The most important channels are:-Herengracht-Keizersgracht-Prinsengracht
