The construction of Khosro Abad dates back to the Qajar era and the year 1808. Amanullah Khan Ardalan Vali, the then governor of Kurdistan, ordered the construction of this building in a space with 6000 square meters. Some believe that the eastern part of the building called the Palace was built during the Zand ear and its development is attributed to Amanullah Khan Ardalan Vali. Although the building was used from time to time as the headquarters of the political government or a military base, most of the time it functioned as a place to perform ceremonies and hailing kings.
