This is where the bridge and lock maintenance department of the city was housed from 1957 till 2014. After that, it became the main location for Mediamatic. At that time the main building had only two storeys and the "portakabin" annex was only one layer high.
The water on the bottom right is the Oosterdok and at the bottom left, there is the "Oosterdoksdoorgang", the passage onder the train bridge and De Ruyterkade that connects Oosterdok to the IJ-river.
On the bottom left you see the current location of cafe Hanneke's Boom.
