Amsterdam Central Station is the transport hub of Amsterdam. The station was built between 1881 and 1889, and was designed by the architect P.J.H. Cuypers. The station has 6 platforms and is built over three islands in the IJ-lake. Just like most buildings in Amsterdam, the station was built on wooden poles - 8687 of them, to be precise. The station is the busiest of the Netherlands, with more than 300,000 travellers daily.
