The Nymphaeum, a semi-circular public fountain, sits near the junction of Wadi Musa and Wadi al-Mataha. Six Nabataean columns adorned its facade, and it received water from a tank located on the opposite side of the valley. This structure, named after the nymphs of classical mythology, served as a public drinking fountain in Petra. The Nymphaeum also served as a gathering place for locals and travelers to socialize and cool off from the desert heat. Its intricate design and strategic location made it a prominent feature in the ancient city of Petra. Although only the lowest levels of its masonry remain, it was once a lively meeting place for the city's populace. Elevated upon a stepped podium, it featured a freestanding wall with porticos and a large central exedra containing the fountain, whose waters flowed into a shallow pool below. Additionally, the water tunnel that diverted water into the city from the Siq passed behind this nymphaeum. The structure is shaded by a 450-year-old wild pistachio tree, adding to its charm and historical ambiance.
