Soltani's House is one of the historic houses of southern Khorasan, which is located in Qa'in's Janbazan Street. The building of the old Soltani house belonged to the Soltani family of landlords and elders of Qa'inat. The ground floor of the Soltani Qa'in home has now become the Museum of Anthropology and is visited by tourists.
The house of Soltani of Ghaen is made at the same time as the old building of the real house (Mir), and due to the many similarities (in terms of architectural design and decorating) between the two buildings, one may have been the architect of both buildings.
The principle of the building of Soltani-Qein's house belongs to the Zandieh period and changes have been made during the Qajar period on the winter porch. In the early days of the Pahlavi period on the southern side of the building and on the south porch (summer), a small porch and a few living spaces were built. In the next periods, the walls are stretched between the two rooms to make the room smaller. This action has made the remaining space behind the exterior walls turn into a warehouse and reduce the beauty of the original space.
