Zanjan Rakhtshooy Khaneh edifice was built by two brothers whose name were Mashhadi Akbar (architect) and Mashhadi Ismaeil (the builder) by the architecture method of the late Qajar era and the early Pahlavi era with the order of municipal manager, Ali Akbar Tofiqi (the mayor of Zanjan in that time) in 1307 SH.
No other building has been identified by the same usage in the other regions of this city. The most significant reason to build this building was creating an appropriate, enclosed and safe place to wash the clothes and dishes by women.
This complex is divided into a management part of Rakhshooy Khane containing the yard, residential area and the main area for washing the clothes which is itself divided into four parts. This building of public utility is unique in the country which has been turned into the Zanjan anthropology museum, and visited by tourists and enthusiasts from 1377 AH to the present.
