Le han est un type architectural lié au commerce et au logement qui s’est développé dans l’ensemble du monde islamique. Le han traditionnel présente un plan à cour intérieure bordée d’un portique à l’arrière duquel sont disposées les cellules. A Istanbul, ce type d’édifice s’est surtout développé dans le quartier commerçant principal de la péninsule historique et dans le Grand Bazar. Son évolution a suivi celle de la ville. Cette étude se concentre sur les han construits entre le début du XVIIIe s. et le milieu du XIXe s. Durant cette période, les échanges entre l’Empire ottoman et l’Occident s’intensifient. En architecture, l’influence occidentale se manifeste d’abord dans le décor puis dans la typologie, tendance observée également dans les han. Par ailleurs, d’autres transformations, liées cette fois-ci à l’évolution interne de l’architecture ottomane, y sont perceptibles. Enfin, le modèle architectural du han traditionnel se transforme peu à peu et à partir du milieu du XIXe s. apparaît un type de han proche de modèles occidentaux. Les divers remaniements dans la ville d’Istanbul, notamment ceux qui ont suivi incendies et tremblements de terre, ont eu pour conséquence la disparition de nombreux han ou leur réfection. L’exploitation d’une documentation très variée (sources d’archives ottomanes, documents graphiques anciens, relevés, plans de restitutions, photographies et autres) et le croisement des différentes données permettent de combler certaines lacunes relatives à la commande, à la construction, aux réparations, aux diverses transformations ainsi qu’aux fonctions des han. / The han is an architectural structure related to trade and housing which developed throughout the Islamic world. The traditional han consisted of an inner courtyard surrounded by a portico that gave access to rooms. In Istanbul, this kind of buildings is mostly located in the main commercial area of the historical peninsula and in the Grand Bazaar. The evolution of the han is linked to the development of the city. This study focuses on the han built between the early 18th century and the mid 19th century. During this period, there was an increasing exchange between the Ottoman and Western worlds. In the field of architecture, the western influence was at first noticed in the decorative elements and later in the architectural typology, a trend that is also valid for the han. In addition, one can observe further changes linked to the evolution of the ottoman architecture itself. Consequently, the architectural model of the traditional han gradually changed through time and by the middle of the 19th century, a type of han very similar to western buildings could be seen. Various changes in the cityscape of Istanbul, particularly after great fires and earthquakes led to the disappearance or restructuring of many han. This work is based on research of a wide range of documents (Ottoman archival documents, historical graphics, plans, restoration projects, photographs etc.) and the cross examination of these data made it possible to find unedited informations concerning patrons, original constructions, repairs, various transformations as well as the uses of the han.

This thesis focuses on the late period mosques of architect Sinan in terms of their structural systems, the relation with their environment, and the identities of their patrons. The links amongst the role of the patron, his or her status in the state, materials used in the mosques, location choice and the spatial distribution of the mosques are researched on the bases of these six late period mosques of Sinan. In this perspective, the social background of the Ottoman Empire in the sixteenth century is the first focal point of the thesis. The relations between the decadence of the institutions, the political conditions of the Ottoman Empire and the architectural production during the last quarter of the sixteenth century are examined in the second chapter of this thesis. In the third chapter these six late period mosques as the sampling case are described in detail and evaluated in terms of their bearing systems, construction materials, the site features and the relation with their patrons. Though, being one of the favorite subjects in the Ottoman architectural history, there are many research and interpretations on Sinan&amp / #8217 / s architectural style, works on late period mosques are limited and not specifically focused. In the fourth chapter of the study these limited interpretations are brought together and evaluated in the light of the background information supplied in the previous chapter of the thesis. In this framework, the aim of this study is not only to assess the late period works of Sinan as a tool to trace his architectural process, but also to unveil the relations with the identities of the patrons and locational and structural features of the mosques.

In this study the Ottoman built environmet in the last period of the nineteenth century Anatolian city is examined. The study aims to explain the construction of new buildings as well as the transformation of earlier types during the process of contemporary modernization and centralization in the Empire. The main frame of the study is formed of the public and the private spaces that formed the urban built environment, and the transformation of these spaces. The city of Tokat has been chosen as the area of study, which still conserves built structures of the Ottoman as well as the earlier periods that are typical of an Anatolian city of the nineteenth century. Examining the transformation of public buildings and residential architecture in this city, this study emphasizes differences in degress of changes in public and private spaces, and the relation of such transformation with the central authority.
