Amsterdam Central Station has been operated since 1889. It is not only a station but it is one of beautiful buildings in amsterdam. Up to now, people are still busy building a tunnel as underwater as underground that connect north amsterdam to the centre of amsterdam, special for the bicycle. Also a subway tunnel from north to the centre. It will be finished in 2017.Not only from outside how beautiful the architecture is, inside you can find more. Look up to the ceiling of the cuypershall (from the main entrance) and also the grand cafe and the waiting room of the royal family. Once in a while there is an open day visiting the tunnel (still in construction) and get information of it.
