Mansourah | Tlemcen

Mansourah (Tlemcen, Algeria)

Overview

Mansourah is a historic fortified city located near Tlemcen, Algeria. It was built in the late 13th century by the Marinid dynasty, specifically by Sultan Abu Yaqub Yusuf an-Nasr during his siege of Tlemcen. The site is famous for its massive city walls, a grand mosque, and the imposing minaret, which still stands today as a landmark of medieval Islamic military architecture in North Africa.

Historical Background

Founded: 1299 CE

Founder: Sultan Abu Yaqub Yusuf an-Nasr (Marinid dynasty)

Purpose: Built as a military base to besiege Tlemcen

Abandoned: Early 14th century after Marinid withdrawal

The Marinids, a Moroccan Berber dynasty, sought to expand their rule into western Algeria, which was controlled by the Zayyanid dynasty. In 1299, Sultan Abu Yaqub Yusuf launched a long siege against the Kingdom of Tlemcen. To support his campaign, he built Mansourah, a vast military city just outside Tlemcen’s walls.

For over eight years, Mansourah served as the Marinid military capital, complete with fortifications, a grand mosque, palaces, and military barracks. However, the siege ended in 1307, when Abu Yaqub Yusuf was assassinated, leading to the eventual Marinid retreat. After their withdrawal, Mansourah was abandoned, leaving behind its impressive ruins.

Architectural Features

1. The City Walls

Mansourah was surrounded by massive walls stretching 5 kilometers, designed to protect the Marinid forces.

The walls were reinforced with towers and gates, reflecting the military Andalusian-Maghrebi architectural style.

Built with mud bricks and stone, the fortifications were designed to withstand long sieges.

2. The Great Mosque of Mansourah

The mosque was built in 1303 CE by Sultan Abu Yaqub Yusuf and remains one of the most important structures of the site.

It followed the traditional hypostyle plan, with a large courtyard and rows of horseshoe arches supported by columns.

The mihrab (prayer niche) was highly decorated with stucco and inscriptions.

Although much of the mosque is in ruins today, its tall minaret remains standing.

3. The Minaret of Mansourah

Height: Originally 38 meters (about 125 feet); today, only a portion remains.

The minaret is built in the Andalusian-Maghrebi style, similar to the Koutoubia Mosque in Marrakesh and the Hassan Tower in Rabat.

It features intricate geometric carvings and decorative calligraphy, showcasing Marinid craftsmanship.

4. The Royal Palace

The Marinid rulers built a luxurious royal palace inside Mansourah, complete with gardens and water features.

The palace followed the Andalusian architectural style, reflecting influences from Seville, Cordoba, and Granada.

Like most of the city, the palace is now in ruins.

Decline and Abandonment

After the assassination of Abu Yaqub Yusuf in 1307, the Marinids withdrew from Tlemcen, abandoning Mansourah. The Zayyanids regained control and never reoccupied the city, preferring their existing capital in Tlemcen. Over the centuries, the site fell into ruin, though its minaret and parts of the walls remain standing.
