The city of Old Gümü?hane was founded on a sloping ground with rich silver mines in the Eastern Black Sea Region. Because of the loss of its socio-economic power in time, it moved to a valley of 1150 m altitude which is 4 kilometres away from its original place of foundation and which is close to the express way. In its place of foundation, the city was called as Argyropolis and Canca respectively. After the onset of the migration of the population from the city, it was called Eski?ehir and Old Gümü?hane respectively; and when it lost its status as a city and reduced to the status of a neighbourhood it was called as Süleymaniye. A close look at the architectural character of the city which transformed into a neighborhood showed that especially a certain mansion among the civil architectural examples had some different characteristics from other historical buildings and had a considerable effect on the civil architectural examples that were built after it. However, it is well-known that the mansion shows the characteristics of buildings in other cities. In other words, it is an imitation of a house in another city (it was found that the house by which it was affected is in one of the cities on the route of the Silk Road). It is interesting that such a building affected other buildings which were built after it especially in terms of the façades and that its identity is so dominant. The main aims of this study are to identify the characteristics of the mansion that affected other buildings, the characteristics of other historical buildings, and the common and different characteristics of the buildings. Furtheremore, the fact that it still maintains its effect although the city transformed into a neighborhood in the historical process, and that the mansion still stands while most of similar examples disappeared in time reveal its importance more clearly. The mansion has come down to the present day but has now been in a very poor condition. It is necessary that the building survey, reconstitution and restoration projects of the mansion be made and the house be handed down the next generations in the context of sustainability.
