Muscat sits wedged between mountains and the Gulf of Oman, a capital that grew up around forts, souks, and whitewashed low-rise neighborhoods rather than the glass towers common to its Gulf neighbors. This episode of the ARTE series on emerging megacities follows the city as Oman opens further to tourism and foreign investment, tracking how planners try to expand a modern port and business hub without erasing the older fabric of the place. Footage moves between the old quarter of Muttrah, its historic harbor and market, and the newer developments rising along the coast, with residents, workers, and officials describing daily life inside a city that regulates its own growth more tightly than most in the region. The film treats Muscat's traditions, from architecture codes to family and religious customs, as active forces shaping urban planning rather than background color. It is a portrait of a metropolis trying to modernize on its own terms.
