The Arsinoe Fountain, located between the Theatre and the northern stoa of the Agora of Messene, is identified with the fountain described by Pausanias. It was named after Arsinoe, daughter of Leucippus and mother of Asclepius. It was constructed at the end of the 3rd century BC and underwent repairs during the 1st and 3rd centuries AD. The monument consists of an elongated reservoir approximately 40 metres long, with a semicircular base for bronze statues in its centre, as well as two lower reservoirs symmetrically arranged around a paved courtyard. During its first phase, at the end of the 3rd century BC, the façade featured a Doric colonnade. During the reign of Nero, bronze statues of the family of Augustus were added. At the end of the 3rd century AD, modifications were carried out with the addition of two square projections, using material from the theatre of Diocletian. The fountain followed the fate of the other public buildings of the city and was abandoned around 360/370 AD. However, part of it continued to be used during the Early Christian period, and it was later reoccupied from the 10th century AD onwards. The water supply came from the Klepsydra spring, which was associated with the myth of the abduction of the infant Zeus. The ancient Klepsydra had monumental dimensions, with a 6 × 12 metre prostyle structure, a pavement made of limestone blocks and a retaining wall. Today, however, its architectural elements have been incorporated into more recent constructions. In the same area there was also a sanctuary dedicated to Achelous, dating from the 9th/8th century BC.
