Located in the Upper Casbah of Algiers, the Sidi Ramdane Mosque is among the oldest religious monuments in the capital. Built before the Ottoman period, it stands out for its simple Maghreb architectural style, featuring stone columns and a square minaret.
The Sidi Ramdane Mosque is one of Algiers' oldest religious landmarks. Traditionally dated to the 10th century during the Zirid period, it reflects the medieval origins of the Casbah. Its prayer hall, supported by stone columns, tiled roofs, and square minaret, exemplifies the sobriety of Maghreb religious architecture.
The mosque complex once included barracks, bastions, a gunpowder storehouse, reserves, and all necessary facilities for its operation. Due to its location and organization, it functioned as a fortified city, relatively autonomous above Algiers.

History and Architecture
The Sidi Ramdane Mosque is situated in the heart of the Upper Casbah, a historic district of narrow alleys, steep passages, and traditional houses.
According to Algeria’s Cultural Heritage Map, its construction dates back to the 10th century during the reign of Bologhine Ibn Ziri. Thus, it was built well before the Ottoman conquest of Algiers in the 16th century.
The mosque is a rare testament to medieval Algiers, then known as El Djazaïr Beni Mezghana. Its location and age help illuminate the early stages of the city’s urban development.
Before adopting the name Sidi Ramdane, the building was called Djamâa El Casba El Kedima—meaning “Mosque of the Old Casbah.” This name reflects its proximity to the ancient Zirid citadel, which once occupied the heights before the construction of the current Ottoman fortress.
The mosque likely marked one of the boundaries of medieval Algiers, reminding us that the history of the Casbah predates Ottoman rule and extends much further back.
The current name is associated with Sidi Ramdane, a pious figure around whom various traditions developed. However, his precise identity and the period in which he lived remain uncertain. Some traditions portray him as a local saint, while others suggest an older origin.
Given the lack of definitive historical documentation, it is best to note that the memory of this figure gradually became linked to the mosque, eventually giving it its current name.
Despite successive transformations in the Casbah, the Sidi Ramdane Mosque has retained its religious function. It was classified as a national heritage site in 1967, and restoration work was carried out to preserve its structure and architecture. According to the Cultural Heritage Map of Algeria, these works were completed in 2011.
The mosque is also part of the protected sector of the Casbah of Algiers, inscribed on the UNESCO World Heritage List since 1992.
Architecture
The Sidi Ramdane Mosque is distinguished by its simple, functional architecture. Unlike many Algiers mosques built or transformed during the Ottoman period, it does not seek monumentality.
Its prayer hall is organized by two rows of nine undecorated stone columns. These supports divide the space into different bays and bear the weight of the tiled roof.
The sloping roofs are covered with tiles, while the minaret has a square plan characteristic of Maghreb religious architecture.
This simplicity is precisely one of the mosque’s main attractions. It allows visitors to observe an architectural tradition predating the Ottoman influences that later shaped many of Algiers’ mosques.
Visiting Tips
The Sidi Ramdane Mosque is not merely a tourist site—it remains an active place of worship and should be visited with respect for worshippers and religious practices.
Its location in the Upper Casbah makes it easy to include in a walking tour connecting historic monuments and neighborhoods around the old medina.
Even when interior access is not possible, observing the facade, minaret, roofs, and the mosque’s integration into its neighborhood is highly worthwhile.
