A handsome 12th-century building in the southern part of the Old City, originally a hospital and medical school founded by Nur ad-Din. The arched entrance and stalactite half-dome above the door are early masterpieces of Syrian Islamic architecture. Inside, the central courtyard has a basin, an iwan (vaulted hall) on each side, and rooms that once held patients now occupied by a small medical museum.
Exhibits cover the development of Arab medicine — surgical instruments, an early apothecary, manuscripts of Ibn Sina and al-Razi. The museum is small and rarely crowded. Find it just south of the Hamidiyah Souq, in the lanes off Madhat Pasha Street.
