Mimar Sinan House (House of Architect Sinan) The birthplace of Architect Sinan, a stone house in the Ağırnas District of Kayseri, has become a popular attraction due to its historical significance and impressive architecture. Sinan served as the "chief architect" during the reigns of Sultan Suleiman the Magnificent (1520-66), Selim II (1566-74), and Murad III (1574-95). The house was made of volcanic stone, which was abundant in the region, and was where Sinan spent the first 23 years of his life. The house also features an arched area, or gallery, that could accommodate up to 150 people at once, as well as a stove and hearth in one room that provided both heating and cooking capabilities. A chimney located on top served for ventilation and lighting purposes. The house is divided into different sections, including areas for people and animals, warehouses, storage rooms, a cellar, and cedar storage spaces. Its stone insulation made it cool in the summer and warm in the winter, which inspired Sinan in his architectural designs. The house was converted into a museum in 2006 and is open to visitors every day from 9 A.M to 4 P.M.
