In the Yakup Aga Complex (Külliye), built by Yakup Ağa in 1547, the treasury chief of Sultan Süleyman the Magnificent, there were a mosque, a madrasah, an imaret (soup-kitchen), a guesthouse and an infants’ school. He sat in the complex and was watched the scenery while sipping his tea. The rising sound of the call to prayer was reflecting the character of the city. She witnessed the beauty of the mother-of-pearl and carving art while she half-opened the door of the mosque. On his wings it was written: “Always open the door of this mosque with joy. I witness to the unity of God.” Adjacent to the imaret, there were domed rooms with porticos and five-domed porticoes used as guesthouses. At the time, religious education and literacy were taught to girls and boys between 5 and 10 years old in infants’ school. In addition, everyone who came to the Complex was regarded as a guest of God, held in high esteem and served with soup at every hour of the day. When he took a deep breath and looked again, he realized that the complex was also a point of meeting and resting for the residents of the city.
