Büyük Valide Han hides Istanbul's most spectacular secret view. The 16th-century building requires finding Mr. Mehdi who controls access. Climb unmarked stairs with extreme caution—unprotected edges everywhere. Recent structural damage restricted entry. Artists with studios inside maintain the relationships that grant access.

Mehmet, last master of this school, binds books with methods that exist nowhere else—accidental cultural preservation.

Crafted in Istanbul documents vanishing workshops. Glassworker Selahattin Usta remembers when Paşabahçe factory employed 200 masters. Now scattered workshops struggle alone.

Named for crows gathering on roof.

Sirän Collective creates temporary freedom through electronic music. Y.unan and Nene H's female-led collective shares locations only through trusted networks. In restrictive environment, underground parties become survival strategy. The secrecy protects community. Music carries messages that cannot be spoken elsewhere.
