The Maassilo in Rotterdam is known for its grain storage in the twentieth century, but turned into an event venue in the beginning of the 2000s. In this thesis, the architectural and urban transformations to the Maassilo and its surroundings are being investigated. It appears that the silo has been of great impact in the bigger network of silo's, but it also has contributed to the image of Rotterdam. Structural, internal and external changes have shaped the silo as it is right now, causing a new way of looking at the reuse of heritage buildings.
