Recognizing "plan spatial organization" and "construction techniques" in the historical buildings of Hozdar City of Sistan with Reference to Historical Sources and Archeological Studies

The vastness of Iran and the climatic zoning in its different regions have made it possible to create architectures with different characteristics during different historical periods in different places, which are valuable for further study and recognition. Unfortunately, these valuable models of native architecture are being lost and destroyed in many parts of the country due to erosion caused by natural and human factors. Due to the lack of study and recognition of these native architectural values, no effort has been made to preserve and revive these works; Therefore, research in these fields and understanding its patterns will help to preserve and revive the valuable native architecture of these regions. Examining the native and historical architecture of different region, especially the unknown regions of Iran, reveals valuable and distinctive features of the country's architecture. Sistan is one of the regions that has many valuable historical buildings in terms of architecture, especially related to the Sassanid and Safavid eras. The city of Hozdar that is located in the northern part of Sistan, has many historical buildings, which, unfortunately, due to being located on the way of river, have been completely damaged and most of them have been destroyed and in only a few of the remaining important buildings of this city, protective measures have been taken to prevent further destruction; therefore, the preservation and revival of these works, which require study, investigation and complete recognition; it is necessary and worthy of attention. There are different settlements related to different historical periods in this city but the prosperity and construction of a huge part of it happened in the Safavid period. In the previous researches, the focus of the researcher was on the landmark building of this region and conducting quantitative climate research on the cooling spaces of this complex.
