Büyük Valide Han, one of Istanbul’s oldest inns, was commissioned in the 17th century by Kösem Sultan, wife of Sultan Ahmed I, to serve as a key trading hub in MahmutPasha Çakmakçılar Yokuşu. Its central Shia Mosque reflects its historical role in hosting Iranian merchants. Over time, irregular modifications by workshop owners created a fragmented structure with over 400 proprietors, complicating restoration. Despite its faded grandeur, the han remains culturally significant, with historic courtyards and a rooftop offering panoramic city views. However, rising tourism, especially after Skyfall, has led to structural damage and now it is fully restored with a restricted access to the top of the building.
