The Palais du Bey, in the historic Sidi El Houari quarter, is the most important piece of Ottoman architecture in western Algeria. The complex of courtyards, reception halls, and private apartments was built in the 1790s when Oran briefly served as the residence of the Bey of the West. Long neglected, the palace has been undergoing a slow restoration; some sections are open to visitors, others remain off-limits.
The standout interiors are the marble-tiled courtyards, the cedar-wood ceilings of the bey's reception rooms, and the small hammam complex. Guided visits — when available — are organised through the Sidi El Houari restoration association.
