In this study, the assumption that each period is in a constant interaction with the previous and following periods was investigated. The locality of this study, Trabzon, was occupied by different societies having different religions, languages, cultures, etc., which created diverse architectural styles but which mutually influenced each other. When we looked at the architectural history of the city, four different styles were found. These styles can be classified into some subheadings: Anatolian Greek-Greek (Roman-Byzantine) Architecture, Ottoman-Turkish architecture, Transition Period architecture and Modern Architecture. The houses examined in this study belong to Anatolian Greek-Greek (Roman-Byzantine) Architecture and Otoman-Turkish architecture (a total of 30 houses). Because the weight of this study is on the facades of the buildings, the planning typology was ignored. The study contains four sections: Introduction, The locality of the study, Method and Results. In the Method section, the sample houses were shown in a table in two main groups as General Characteristics and Facade Elements. The general characteristics consist of. the number of floors, and symmetry. Facade elements consist of. horizontal-vertical bands, eaves, entrance positions, bay windows, and windows.
