We saw very different structures over the last couple of days in Western Libya, in the Berber communities of Nalut and Yefren. All of these are essentially a community bank vault, food storage facility, and architectural wonder in mud brick. Each was built in the best defensive position in the area - high up over the town, or backing onto a cliff edge. They all possess a great sense of humanity in their design - clay smoothed back by human hands, based entirely on human proportions, unadorned and rough at the edges but beautiful for their simplicity, purpose, and the nature of their materials.
