 
The hart of Jerusalem's water supply: the three Solomon's Pools, 5 km
 south-west of Bethlehem. Two supplying aqueducts enter from the south.
 The Low Level and the High Level aqueducts exit to the east. The dotted
 line at right / east represents the start of the aqueduct towards Herodion.
 Note the several additional springs ('Ain-s) including the one under
 the lower pool.
