Overview
In 1195, Almohad Sultan Yacoub al-Mansour ordered the construction of what was intended to be the largest mosque in the Islamic world, with a minaret rivaling any building on Earth. When al-Mansour died in 1199, construction halted abruptly. The minaret, known as the Hassan Tower (Tour Hassan), reached only 44 meters of its planned 86-meter height. The mosque's 348 columns were left standing without walls or roof. A 1755 earthquake damaged much further. Today, 200 of those stub columns still march in rows across the elevated platform, and the incomplete sandstone tower stands as Rabat's most recognizable landmark.
Adjacent stands the Mausoleum of Mohammed V, completed in 1971 to house the tombs of the modern monarchy's founder and his sons, Hassan II and Prince Abdallah. A guide connects the Hassan Tower to its Almohad architectural siblings — the Koutoubia in Marrakech and the Giralda in Seville — all three designed with the same proportions and decorative vocabulary. Combine with the Kasbah of the Udayas (15-minute walk) and Chellah for a complete Rabat day.
Visitor Etiquette
The Hassan Tower esplanade and the column field are open to all visitors without dress code restrictions, as the mosque itself was never completed and no active place of worship stands on the main platform. However, the Mausoleum of Mohammed V adjacent to the tower is a royal tomb and active religious site — different rules apply there. To enter the mausoleum: dress conservatively (shoulders and knees covered for both men and women; women should cover their hair as a mark of respect, though this is not always enforced for foreign visitors), speak quietly, and follow the clockwise circumambulation direction around the central sarcophagi. Photography inside the mausoleum is not permitted — the Royal Guards who stand watch will intervene if cameras are raised. Non-Muslim visitors are welcome inside the mausoleum. Do not touch the ornamental railings or lean over the interior balustrades. On the tower esplanade itself, photography is unrestricted and the atmosphere is relaxed; the changing of the guard at the mausoleum entrance is a formal ceremony observed from a respectful distance.
Spiritual Significance
The Hassan Tower encodes one of the most audacious religious ambitions in Islamic history. When Sultan Yacoub al-Mansour commissioned it in 1195 CE, fresh from his crushing victory over the Castilian army at the Battle of Alarcos, he envisioned a mosque that would hold 40,000 worshippers and a minaret that would be the tallest structure in the Islamic world at a planned 86 meters — surpassing even the Koutoubia in Marrakech and the Giralda in Seville, the two Almohad minarets that served as its architectural siblings. The unfinished tower stands at 44 meters, frozen at the moment of al-Mansour's death in 1199: a monument to both the reach of Almohad imperial theology and its sudden collapse.
The Almohad dynasty grounded its political legitimacy in a rigorous Islamic reform movement, and this mosque was intended as the physical statement of that ideology — the qibla encoded in its precise orientation toward Mecca, the decorative geometric tracery on each face of the minaret expressing the dynasty's theological rejection of figural representation. The 200 column stubs that still march across the platform are the footprint of a prayer hall that was never roofed, making the entire esplanade an accidental open-air mosque of extraordinary scale.
The adjacent Mausoleum of Mohammed V — completed in 1971 to house Morocco's first post-independence king — deliberately anchors the Alaoui dynasty's modern legitimacy to this medieval Islamic monument, fusing the country's ancient faith with its national sovereignty in a single sacred precinct that remains active today.
