Illuminating History with Fiberli We are proud to have designed the exterior lighting for the T.C. İş Bankası Museum, a historical gem located in Istanbul’s Eminönü district. Originally built as a post office in 1890, this iconic building served as a T.C. İş Bankası branch from 1927 to 2004 and reopened as a museum in 2007. Now beautifully illuminated with Fiberli fixtures, it stands out as a landmark of the historical Eminönü Peninsula both by day and by night.
