Taza is the home of two 12th century mosques, the Andalous Mosque and the Grand Mosque. The latter is the most important of the two, possibly being the oldest Almohad structure in existence, founded by Sultan Abd el-Moumen. It is believed to predate the mosque at Tin Mal.
Both mosques are hard to take in while walking the streets, they belong to a period when houses were built as close to mosques as possible. The minaret of the Grand Mosque stands out clearly from the silhuette of Taza, seen from a distance.
The interior of both are interesting and attractive, but since this is Morocco, closed for non-Muslims.
