The Bassin Souani, located in Meknes, Morocco, is a historic water reservoir built during the reign of Sultan Moulay Isma'il in the late 17th century. The massive structure, part of the larger Imperial City, served as a granary and water supply for the kasbah. Visitors can explore the vast open-air basin, the adjacent House of the Ten Norias, and the impressive hydraulic system that once distributed water throughout the palace. The site offers a glimpse into the advanced infrastructure and architectural prowess of the time.
