The water was raised into an aqueduct via a huge noria (waterwheel) measuring 26 metres in diameter and 2 metres wide.[1][2][3]:68 The noria, sometimes referred to as the "Grand Noria", was located next to Bab Dekkakin.[4][4] Its enormous wheel was made of wood, reportedly covered in copper, and held up on a stone base.[3][7] From Bab Dekkakin, the aqueduct then carried the water to Bab Segma further north, and from there it was carried further into three large square basins spread across the gardens.[4][5] According to one historical source, at least three other norias operated inside the gardens and were crucial to their existence.[7] Also located inside the gardens was a msalla, an open-air prayer area, known as the Msalla of the Sultan or the Msalla of Bab Segma.[5]
