Sidi Okba Mosque

The Sidi Okba Mosque, located in Sidi Okba, Biskra, Algeria, is one of the oldest mosques in the Maghreb, built in 686. Constructed from wood, palm trunks, stone, lime, and plaster, its interior features metal, wood, and ceramic decorations.

The mosque traces its origins to the 7th-century Muslim conquests. Oqba Ibn Nafaa, the Umayyad governor of Ifriqiya, died in 683 in present-day Sidi Okba, and his mausoleum became the foundation of the mosque in 684. Over time, it evolved into a cultural hub, inspiring scholars and showcasing Medinan architectural influences. It was expanded in 1025 by Zirid ruler Al-Muizz ben Badis.

Its prayer hall features seven parallel naves, an arrangement typical of Umayyad mosques. Horseshoe arches rest on palm trunk columns, a design inspired by Medina and later found in Central Asia and Anatolia. The mihrab, adorned with red and green paint, is topped with a fluted half-dome, a motif traced to early Islamic art. The adjacent minbar features intricate wood carvings.

The mausoleum of Oqba Ibn Nafaa was embellished during the Zirid era. Its Kufic-inscribed tombstone dates to the 11th century. The mosque’s square minaret, decorated with niches and arches, ends with merlons.

In 2009, the mosque became part of a modern Islamic complex with a new prayer hall, school, library, and conference center. The original structure, now enclosed by porticoes, serves as a site for reflection, honoring the legacy of Oqba Ibn Nafaa.

Masjid Sayyidi 'Uqba was constructed upon the gravesite of 'Uqbah ibn Nafi,' the Arab general who oversaw the Islamic conquest of the Maghreb in the first century of the Hijra, 20 kilometers from Biskra. It is Algeria's oldest mosque that is still in use.
