Pirenium was the most remarkable fountain in Ancient Corinth, a place of mettings, relaxation, recreation and discussions. “The water around Pirenium is wise” says Pausanias sententiously.

    In that source Vellerefontis broke in Pigasos with a bridle Athena gave to him and that is why in Ancient Corinth people call the goddes of wise “Halinitis”.

    The water of Pirenium was collected from the area around with four tunnels and flow in three reservoirs from where was piped in six domed chambers.

    In front of the chambers there was a parapet from the 5^th century BC, which they used to support their pitchers on, so as to fill them with water, the specialist water-carriers. The fountain had a Doric porch in front which underwent modifications in 2^nd century BC. The new form, however changed again during the 2^nd century AC when Herod the Attic embellished it by spending a respectable covering and a sculpting-painted decoration.

    In the hollows they placed statues and inside the chambers there were portrayals of fish in the sea as we can even today confirm in the 4^th chamber of the fountain.

    In Byzantine period, the sight of Pirenium changed again. The Byzantines took from the Apollo’s temple yard a few pillars and modified the external reservoir in an arched colonnade.

    In the middle ages, the yard of Pirenium was used as a cemetery. In the South-West corner of it a Christian chapel was also built.
