Bastion 23 was the final remaining part of the lower Casbah neighborhood after the French colonial demolition campaigns of the 19th century.
The complex takes its name from the 'Raïs' or pirate captains who historically resided in these palaces during the Regency of Algiers.
The buildings include a unique subterranean system designed for ventilation and defense against naval bombardment.
Archaeological restoration in the late 20th century uncovered original Ottoman-era plumbing and drainage systems still visible today.
The interior courtyards were designed with a 'sqifa' (bent entrance) to ensure privacy from the street, a hallmark of traditional North African domestic architecture.
Raïs Palace, known locally as Palais des Raïs or Bastion 23, is a complex of three Ottoman-era palaces and several residential houses constructed between the 16th and 18th centuries in the Casbah of Algiers. It is one of the few surviving historical structures in Algiers that demonstrates the transition from Ottoman-style residential architecture to the colonial period. The site was originally situated on the waterfront, serving as a defensive bastion before the French colonial authorities reclaimed the sea and built the current harbor frontage. It currently functions as a Centre for Arts and Culture, hosting exhibitions and workshops within its preserved interiors. The architecture features traditional ceramic tiling, carved cedar wood, and intricate plasterwork typical of Moorish design. The buildings are interconnected by a network of narrow passages and courtyards, showcasing the dense urban planning of the pre-colonial Casbah.
The arched windows and balconies overlooking the Mediterranean sea offer the most iconic views of the coast against the traditional white stucco walls.
Wear comfortable, flat walking shoes as the floors are made of uneven, historic ceramic tiles and stone.
Bring a portable battery for your phone, as the thick masonry walls can drain devices faster than usual.
Coordinate your visit with a local guide to access rooms that are occasionally closed to the general public during private exhibitions.
Avoid driving directly to the site, as the surrounding streets in the Casbah are extremely narrow, congested, and difficult to navigate for non-local vehicles.
Closed on Fridays and public holidays.
Maintain a quiet demeanor as the site often hosts delicate art exhibitions; shoulders and knees should be covered out of respect for local cultural customs.
