text: MUD IS a versatile building material that has been used to make some extraordinary architectural marvels -- from 1,000-year-old ksars (forts) in Morocco and 6,000-year-old arches, vaults and domes in the Nile Valley to multi-storeyed houses of adobe, sun-baked bricks of mud and straw, which is the traditional building material throughout much of Latin America.
