Broad daylight pours in through large-scale arched windows, illuminating a hall that proudly presents itself as a cathedral of technology. The control desks appear to be altars, some of them as large as cupboards, others arranged in a semi-circle as if imitating a sacred choir. From here the eyes wander over a broad engine room containing four huge as well as ancient turbine generators made by AEG, Brown Boveri, Siemens and Thomson Houston. The former Ottoman power plant Silahtarağa on the Golden Horn of Istanbul owes much of its intact appearance to its meticulous restoration. Today it houses the santralistanbulMuseum of Energy. The museum's basement features interactive exhibits offering fun-meets-science experiments that focus on electricity and power generation.
