Beit al-Tutunji is an early 19th-century merchant's house in the Old City of Mosul and one of the best surviving examples of Moslawi Ottoman vernacular architecture. The house was built by a prominent local trading family and features the characteristic features of the style: a central courtyard with an iwan (vaulted reception hall), elaborate carved plasterwork, and mashrabiya lattice screens on the upper windows that allowed women of the household to see the street without being seen.
Houses of this type were the urban fabric of the old Tigris cities — Baghdad, Mosul, Basra — before modernisation tore most of them down. In Mosul, war and decades of neglect have destroyed most of the remaining examples, making Beit al-Tutunji all the more valuable. Conservation efforts have kept the structure in reasonable shape, and it serves as a reference point for the wider Old City restoration project.
