Fountain of Peirene. In the sunken rectangular area, built in the second century A.D., jugs could be filled at water spouts. Behind the sunken pool, arches provide access to a series of underground reservoirs where, in the early first century A.D., water was drawn. A statue of the nymph Peirene originally presided over this fountain; according to legend, Peirene was turned into a spring of water by the tears she cried when her son was killed.
