The oldest examples in Marrakesh date to the Saadian period (16th-17th centuries), such as the Dar Cherifa (formerly known as Dar Ijimi), the Dar al-Mas'udiyyin, and the Dar al-Masluhiyyin (known also as Ksour Agafay).[52] The Mouassine Museum also contains an example of preserved Saadian-era douiria, or upper-floor guest apartment.[62][63]
