It is the person who makes the space meaningful. The space that exists together with people gains meaning together with them. People direct their attitudes and behaviors within the space they are in. The design and design language of the space they are in are effective in directing their attitudes and behaviors. The design language is formed with the design elements that form the design. Structures that are in the society and have a place in the collective memory of the city are recognized by the society. The culture and lifestyle that affect the culture as a whole of values that the society has also affect the recognition of the structure that has an important place in the city's memory. The person who experiences the structure will inevitably be affected by the atmosphere of the structure and will direct their behaviors thanks to the architectural language it has. Knowing this architectural language will make the communication stronger by ensuring that the structure is perceived and the messages given by the structure are perceived more clearly. Historical places give certain messages to their users with the architectural language they gain thanks to the architectural style they have. For this reason, in the study, the extent to which the gains created by architectural education affect the communication established with the structure has been discussed together with the analyses made. (This study was carried out by applying the method developed in the author's master's thesis titled "Legibility of the church and the complex structures in Turkey", completed in 2018 under the supervision of Mehmet İnceoğlu.)
