Photo by George Steinmetz @geosteinmetz | The 16th-century walled city of Shibam provides a remarkable skyline amid the flat, arid backdrop of the Arabian Peninsula’s Empty Quarter. About 500 multistoried mud buildings are clustered together, some interlinked by midair passageways. The towers are constructed with sunbaked bricks of soil, hay, water, and palm wood, making this weathered metropolis a living monument to medieval ingenuity. The city endures as one of the earliest and grandest urban models to use vertical architecture.
