Context: Amsterdam Centraal was designed by Pierre Cuypers, who is also known for his design of the Rijksmuseum in Amsterdam. While Cuypers was the principal architect, it is believed that he focused mostly on the decoration of the station building and left the structural design to railway engineers. The station was built by contractor Philipp Holzmann. The new central station replaced Amsterdam Willemspoort Station, which had closed in 1878, as well as the temporary Westerdok Station used from 1878 to 1889. The idea for a central station came from Johan Rudolph Thorbecke, then the Netherlands Minister of the Interior and responsible for the national railways, who, in 1884, laid two proposals before the Amsterdam municipal council. In the first proposal, the station would be situated between the Leidseplein and the Amstel river. In the other, it would be built in the open harbour front allowing for the station to be connected to the existing main lines in the area to the west and the south, but also to a projected new northern line.
