The Mashhad al-Husayn a free-standing structure sited in Aleppo. It was constructed in five phases spanning a period of 519 years, starting from the first building phase in 717-719. The Mashhad incorporates a rich variety of structural and ornamental features such as the domed chambers' transition zones that progress from four walls. One additional feature of particular note is the pyramidal ceiling in the kitchen. The restoration revived both the historic architectural features and the religious functions of the Mashhad. In the process of reconstruction, a team of skilled craftsmen were trained in restoration techniques.
