The Mansourah Ruins: A Monument to a Siege
Discover the captivating history of Mansourah, a vast city built solely to besiege Tlemcen, and marvel at its towering solitary minaret.
A few kilometers west of Tlemcen lie the imposing ruins of Mansourah (“The Victorious”). Unlike most ancient cities that grew organically over centuries, Mansourah was born out of a single, highly ambitious military objective: to lay siege to the seemingly impregnable Zianid capital of Tlemcen.
A City Built for War
In 1299, the Merinid Sultan Abu Yaqub Yusuf of Fez arrived with his army, determined to conquer Tlemcen. Finding the city’s defenses too strong to breach quickly, he settled in for what would become one of the longest sieges in history, lasting eight years.
Instead of a temporary military camp, Abu Yaqub Yusuf ordered the construction of a permanent, fully-functioning city. Mansourah was built with massive protective walls, a royal palace, bathhouses, caravanserais, and a magnificent central mosque. It became a thriving metropolis, minting its own coins and attracting merchants from across the Mediterranean, all while its soldiers continuously besieged Tlemcen just down the road.
The Grand Minaret
The siege ended abruptly in 1307 with the assassination of Abu Yaqub Yusuf, and the Merinids abandoned Mansourah. Though they returned decades later for another siege, the city was eventually left to ruin.
Today, the most striking feature of Mansourah is the remains of its great mosque, specifically its towering minaret. Standing at nearly 40 meters high, the minaret of Mansourah is a masterpiece of Moorish architecture, often compared to the Giralda in Seville or the Koutoubia in Marrakech.
What makes it truly unique is that it is sliced perfectly in half vertically. The front facade, adorned with exquisite carved arches and geometric patterns, stands tall and defiant, while the back half has completely collapsed. This striking silhouette has become one of the most iconic symbols of Tlemcen.
A Walk Through History
Walking along the remaining stretches of Mansourah’s massive adobe walls, which once enclosed over 100 hectares, you can’t help but feel the immense scale of the Merinid ambition. The ruins are surrounded by tranquil olive groves today, offering a stark contrast to the violent purpose for which the city was built.
A visit to Mansourah is a powerful reminder of the turbulent history of the Maghreb, where empires clashed, and stones still bear witness to their epic struggles.
