Mohamed el-Hajj is a man of vision, the most grandiose of which came to fruition some thirty years ago, when he built seven mosques in his hometown on a shoestring budget. Six of the mosques were built at the top of Bani’s main hill. They are directed not toward Mecca, but instead face a larger mosque in the center. Erected in the early nineteen-eighties, the crumbling adobe mosques have prematurely weathered for lack of maintenance, making them look much older than they actually are. In a country with little or no heritage sites, the controversial mosques put the small town of Bani on the map.

Mosque of the Setting Sun is currently in degradation, even though it is still used on Special religious occasions. The original form, openings, and even ornamentation can be seen on exterior facades.

The mosque is 11 meters in length, 7,5 meters in breadth, and 6 meters in height. The minaret was 17 meters tall when it fell in 2010.
