Tour Hassan and the unfinished grand mosque of Rabat

In Rabat, Tour Hassan rises above the Bou Regreg as an unfinished Almohad minaret surrounded by a vast mosque platform that never reached completion.

On a rise above the Bou Regreg estuary in Rabat, Tour Hassan stands as an unfinished Almohad minaret surrounded by the traces of a vast mosque that was never completed. Commissioned by the Almohad caliph Abu Yusuf Yaqub al-Mansur in the late twelfth century, the project left a monumental footprint even in its incomplete state, with the tower reaching 44 m (144 ft) and a wide prayer hall marked by hundreds of stubby columns.the minaret of an incomplete mosque

An Almohad ambition frozen in stone

The architecture of Tour Hassan and its mosque platform

The tower follows the Almohad minaret type, built in warm-coloured stone with a square plan and robust walls articulated by shallow surface reliefs and ornamental panels.a red stone minaret of Almohad date Inside the minaret, a gently rising ramp curls upwards, wide enough for a rider on horseback, which reflects a pattern also seen in other great Almohad towers such as the Koutoubia minaret in Marrakesh and the Giralda in Seville.an internal ramp for the muezzin

At the base, Tour Hassan stands on a broad terrace that accommodated the projected mosque, whose prayer hall and courtyard were laid out on a large rectangular plan. Only the lower parts of the mosque survive, in the form of fragments of sandstone walls and rows of short column stubs that map out the intended bays of the hall.the minaret of an incomplete mosque Many sources note around 200 to more than 300 column fragments across the platform, marking a forest of supports that never carried its full roof.columns from the unfinished hall

From earthquake damage to a ceremonial landscape

In the eighteenth century, an earthquake associated with the Lisbon event of 1755 caused considerable damage to structures across the western seaboard, and accounts describe the mosque at Tour Hassan among the buildings that lost much of their standing fabric.earthquake damage in 1755 The minaret remained upright on its platform, surrounded by broken columns and partial walls, which gave the site its distinctive ruin-like appearance framed by later landscaping.

In the twentieth century, the area around Tour Hassan was reshaped into a ceremonial ensemble when the Mausoleum of Mohammed V was built on the edge of the platform, creating a composition in which the Almohad tower and the modern mausoleum face one another across a paved expanse.a monumental ensemble with Mohammed V’s mausoleum The ensemble, including the tower and mausoleum, is recognised as part of the heritage zone of Rabat that was inscribed on the UNESCO World Heritage List in the 1990s.listed on the UNESCO World Heritage List
