The Palais des Rais (Arabic: قصر الرياس), also known as Bastion 23, is a classified historical monument located in Algiers, Algeria. It is notable for its architecture and for being the last surviving quarter (houma) of the lower Casbah of Algiers, a UNESCO World Heritage Site. Consisting of three palaces and six houses, whose history began with the construction of Bordj-Ez-zoubia in 1576 by the Dey Ramdhan Pasha in order to reinforce the means of defence of this side of the Medina, this quarter ended up being detached, and even isolated from its traditional environment following the restructuring of the lower Casbah during the French period. It was not until 1909 that Bastion 23 was classified as a Historical Monument under the name Group of Moorish houses. The site was classified as a UNESCO World Heritage Site in 1992.

1. History

The history of the Palais des Rais dates back to 1576, when Dey Ramdan Pasha constructed Borj El-Rais (Tower of the Rais) to strengthen the defenses of the lower city. Over time, the site earned several names, including Qaa El-Sour, Sabaa El-Tabran, and Toubanet Arnaout, reflecting its defensive purpose and the artillery brought by Rais Yahia. During the French colonial era, the structure was renamed Fort 23 following the construction of the city's defensive walls. The numbering of the palace (e.g., Palace 16, Palace 17) and the adjacent "Fishermen's Houses" was introduced during the surveying efforts of the same period. The sole historical reference available pertains to Palace 18, which was built by Rais Mami Arnaout around 1750.

1. Colonial period

After 1830, the year of Algiers' occupation, Palace 18 underwent several changes in function. It initially served as the residence of the Commander of Civil Engineering. Subsequently, it became a boarding school for girls, followed by its use as the United States Consulate Office. Later, it was repurposed as the residence of the "Duke of Aumale" and finally transformed into the municipal library.

1. After independence

After Algeria's independence in 1962, Algerian families occupied the historic site, leading to certain alterations. While this occupation caused some damage to the structure, it also contributed to preserving specific wooden artifacts in relatively good condition. However, the building suffered from exposure to climatic factors and its proximity to the sea, resulting in harmful effects that eventually posed a risk of collapse. In 1980, the Ministry of Culture initiated a phased intervention to safeguard the historic landmark. The first step involved relocating residents to alternative housing, followed by conducting studies and restoration efforts. These measures aimed to transform the site into what would later become the Center for Arts and Culture at the Palais des Rais (Fort 23). The primary goal of the restoration project was to rehabilitate and adapt the structure for optimal use. Restoration work continued from 1987 to 1993, and the palace was officially opened to the public in 1994.

Voûtes de la basse Casbah d'Alger

Les voûtes de la basse Casbah d'Alger, appelées également voûtes de Khayr ad-Din en référence à l'amiral Khayr ad-Din Barberousse, désignent un ensemble de structures voûtées situées dans la partie basse de la Casbah d’Alger, à proximité du port d'Alger. Construites ou réaménagées sous la Régence d’Alger à partir du XVIe siècle, ces voûtes servaient de casemates, d’entrepôts et d’abris militaires en lien avec l'Amirauté d’Alger. Certaines portions de cet ensemble architectural pourraient toutefois remonter à des périodes antérieures, notamment à l'époque antique d'Icosium, en tant que soubassements ou fondations. Aujourd’hui, ces voûtes subsistent partiellement, et font l’objet de programmes de restauration et de réhabilitation dans le cadre de la préservation du patrimoine de la Casbah classée à l’UNESCO.
