The mosque bears the name of Sidi Ramadan, one of the troops who took part in Uqba ibn Nafi’s early Muslim conquests of North Africa. Ramadan was named the city’s chief by Uqba when Algiers was taken over. After passing away, he was interred inside the mosque’s pillar. According to a different story about the origin of the name, Sidi Ramadan was a kind-hearted wali of Biskra. The mosque was actually known as Al-Qaid Ramadan Mosque, according to Sheikh Abdurrahman al-Gilani. He also mentions Ibn al-Mufta, who made significant contributions to the mosque’s foundation.

With a hypostyle prayer hall split by rows of arches supported by columns, the mosque has a very straightforward shape. Elevated galleries or balconies that serve as the women’s prayer area are located along the hall’s three outside sides. The minaret that is connected to the mosque contains sebka carvings on its exteriors. Next to the mosque is a modest, independent mausoleum where Sidi Ramadan’s remains are kept.
