Topkapı Palace was the main residence of the sultan and his court. It was initially the seat of government as well as the imperial residence. Even though access was strictly regulated, inhabitants of the palace rarely had to venture out since the palace functioned almost as an autonomous entity, a city within a city. Audience and consultation chambers and areas served for the political workings of the empire. For the residents and visitors, the palace had its own water supply through underground cisterns and the great kitchens provided for nourishment on a daily basis. Dormitories, gardens, libraries, schools, even mosques, were at the service of the court. Attached to the palace were diverse imperial societies of artists and craftsmen collectively called the Ehl-i Hiref (Community of the Talented), which produced some of the finest work in the whole empire.
A strict, ceremonial, codified daily life ensured imperial seclusion from the rest of world. One of the central tenets was the observation of silence in the inner courtyards. The principle of imperial seclusion is a tradition that was probably continued from the Byzantine court. It was codified by Mehmed II in 1477 and 1481 in the Kanunname Code, which regulated the rank order of court officials, the administrative hierarchy, and protocol matters. This principle of increased seclusion over time was reflected in the construction style and arrangements of various halls and buildings. The architects had to ensure that even within the palace, the sultan and his family could enjoy a maximum of privacy and discretion, making use of grilled windows and building secret passageways.
