Historical sites are structures, monuments, or areas that carry the traces of the past and hold significant importance in the collective memory of society. The cultural, historical, and architectural value of historic places is important for visual perception. Visual quality analysis aims to assess the physical condition and appearance of these historic places and to identify their conservation and maintenance needs. This analysis plays an important role in the decisions to be taken for the preservation of the place. The parameters that influence visual quality reflect the preservation and maintenance of the place, the visitor experience, the importance of cultural heritage for conservation, tourism and economy, and social awareness. Visual perception of historic places refers to how people perceive these places and how this perception is associated with the historical, cultural, and architectural features of the place. The visual perception of historic places may vary depending on various factors. The visual perception of historic places is important for their preservation, visitor experience and the continuation of cultural heritage. While a positive visual perception of historic places can make them more valuable and important in society, a negative perception can damage their reputation and make it difficult to preserve them.
