PHOTO GALLERY: KRAFTWERK CHARLOTTENBURG
Built at the turn of the 20th century, when Charlottenburg was still independent from Berlin, the Kraftwerk Charlottenburg sought to meet the robust electrical needs of the wealthy, growing city. Large pipes transported most of the power across the Spree, which built into the structure of an elaborately-ornamented stone-and-metal footbridge, the Siemens-Steg. Over the following century, its output expanded to include hot water and natural gas, and was able to emerge relatively unscathed from the Second World War.
