The Larabanga Mosque is built in the Sudanese architectural style in the village of Larabanga, Ghana. It is the oldest mosque in the country and one of the oldest in West Africa. The Larabanga Mosque and has been referred to as the "Mecca of West Africa".
Originally founded in 1421, it has undergone restoration several times since. The World Monuments Fund (WMF) lists it as one of the 100 Most Endangered Sites. The restoration works have revived the knowledge of mud-plaster maintenance.
The mosque has an old Quran, believed by the locals to have been given as a gift from heaven in 1650 to Yidan Barimah Bramah, the Imam at the time, as a result of his prayers.
The mosque, built with mud and reeds, has two tall towers in pyramidal shape, one for the mihrab which faces towards Mecca forming the facade on the east and the other as a minaret in the northeast corner. These are buttressed by twelve bulbous shaped structures, which are fitted with timber elements.
Unlike mosques situated in urban surroundings in West Africa, the Larabanga Mosque is comparatively small. Rural mosques, like Larabanga's, were usually conceived by a single marabout and loosely based on styles seen elsewhere such as in the Great Mosque of Djenné. In order to achieve a physical resemblance to the architecture used elsewhere, the Larabanga Mosque had to incorporate large buttresses in order to compensate for the poorer quality of building materials.
Larabanga is one of eight ancient and highly revered mosques in Ghana, and is also the oldest. It is a place of pilgrimage and is considered the Mecca of West Africa.
In the 1970s, a mixture of sand and cement was applied to the external faces of the mosque with the intention of protecting the mosque from wind and rain damage. However, this treatment resulted in substantial damage to the building as moisture became trapped in the walls built of mud and started a deterioration process of the structure, with termites infesting the wooden supports under humid conditions. This resulted in part of the mosque collapsing and during the repair work it caused some distortions of the structural elements and the exterior of the mosque.
Owing to the effect of prevailing winds and rains on the walls, the mosque has needed several renovations and restoration work which over the years have altered some of its exterior designs. In September 2002, a severe storm destroyed the mihrab and the minaret.
The Ghana Museums and Monuments Board decided to restore the mosque and sought advice from CRAterre, an architectural firm based in Grenoble, France with expertise in building earthen structures. The conservation process involved removal of the earlier cement plaster from the surfaces of the mosque, the wooden structural components were replaced, the minaret and the mihrab were reconstructed, the portal was redone, and the interior and exterior surfaces were plastered in the traditional way.
