Photograph of Florence Nightingale's tower at the Selimiye Barracks at Scutari, Constantinople (modern-day Istanbul). The barracks are seen from the side, with one seven storey tower in the forefront and another visible behind. There is a flagpole on each tower.

The Selimiye Barracks were used by the British as a military hospital during the Crimean War. Florence Nightingale, the pioneering nurse, lived in a tower of the barracks whilst working in the hospital. It is likely that James Robertson, who was living in Constantinople, photographed the tower knowing the growing interest the British public had in her work.
