After Palangan, Khosro Abad was chosen as the government seat by Ardalans. The complex that is known as Khosro Abad, is made of two major parts: 1) the royal palace with columned entrance, and 2) the eastern buildings with columned iwans, baths, and guards room. The buildings are surrounded by gardens with streets that pass through them and resembles Isfahan’s Chahar Bagh. Some believe they were first built in the Zand era but were reconstructed and completed by Qajars. At the entrance of the complex, there is an inscription, a poem in Farsi, explaining that the garden was made by the behest of Fath-Ali Shah, the Qajar king, and Amman Allah Khan, the ruler of Sanandaj and dedicated to Amman’s son, Khosro, who the garden is named after. Later the function of the mansion changes and it is used for ceremonial occasions, such as weddings (Fath-Ali Shah’s daughter married Amman’s son in this place) or as a temporary residence of Kings and high-rank officials that visited Sanandaj. the main palace is built in three stories; the second story is accessible through a staircase in the yard. The interesting thing is that the size of the floors decreases as you go up, so the third floor is smaller than the second floor and the second floor is smaller than the first one.
