Today I visited the Topkapi Palace, a massive complex just behind the Aya Sofya. The material palette is magnificent and most of the rooms within the palace have stunning ceilings. My favorite part of the palace was the harem, not because of its programmatic implications, but simply because its spaces were seductive.
This form of natural lighting occurs numerous times throughout the harem. It caught my attention not just because it's formally interesting, but it's rather effective and projects unique patterns on the lit surfaces. These small openings provide a nice, warm, soft light that enables the space to glow.
