Sidi Abderrahmane is a mosque and mausoleum named after the city’s patron saint. The main building was constructed in 1627, and the mosque where locals pray was added in 1696. The mosque also has a small graveyard, where some very notable people are buried, including Sidi Abderrahmane himself.
It was decided in 1020 H/1611 that the sepulchre of Sidi Abdarrahman al-Thaalibi, the patron saint of Al-Djazair, who died in AH 877/AD 1470, should be covered with a qubba (dome). Later on, in AH 1108/AD 1696, Dey al-Hadj Ahmad al-Atchi ordered the square mausoleum to be transformed into a prayer hall, notably through the introduction of a mihrab. Four pairs of columns that are semi-engaged in the walls enable the transition from a square layout to an octagonal one, to accommodate the dome that covers the hall. As well as the two marble columns that flank it on either side, the mihrab is decorated with faïence tiles. The qubba encloses a certain number of sepulchres, including those of Sidi Abdarrahman and Sidi Boudjemaa, and the function and living quarters and buildings could have been constructed with the revenues from the zawiya. Within the enclosure, a small cemetery holds the tombs of illustrious or notable persons such as Sidi Boudouma, Sidi Ouaddah or Dey ‘Umar.
