For centuries, the valley beneath Jerusalem’s Old City held water that sustained the city above. Today, on warm summer nights, the same place fills with music, light, and thousands of people gathered for concerts and festivals. The Sultan’s Pool began its life as a vital piece of Jerusalem’s water system, a reservoir designed to collect and store precious rainwater for the city above. Over time, the pool’s purpose has shifted dramatically. What once sustained life in Jerusalem now sustains its cultural life, transforming an ancient infrastructure into one of the city’s most remarkable open-air venues.
