Bimaristan Arghun Al-Kamli or Bimaristan al-Arghuni, also known as Argun Bimaristan or Arghun al-Kamili Bimaristan, is a historic medieval hospital located in Aleppo, Syria. It was built in 1354 by the deputy sultan Arghun Al-Kamli who represented the Mamluk sultanate in Aleppo. The bimaristan consists of three main wards, the first one is for critical cases, the second one is for ordinary disease cases, and the third one is allocated for women and also includes a section for convalescence. The Bimaristan of Arghun Al-Kamli, which is considered one of the most important hospitals built in the Islamic world, was inscribed as a UNESCO World Heritage Site in 1986 as part of the ancient city of Aleppo.
