Acrocorinth castle: fountain situated outside of the third Gate between the two towers (Google earth).
The fountain is situated between the two towers flanking the southern facade of third Gate, which leads to the 3rd enceinte. The general form of the fountain’s structure shows the characteristic features, which are applied to a common Turkish çeşme: it presents a square shaped form of general dimensions 3,10×2,90 m., and is covered with a stone vault. Its façade was decorated with an arch -as evidenced by the surviving imposts, which has though been damaged in great extent and only the remains of the internal “tympanon” may detect its initial semicircular or segmented form. A small niche 0,30×0,35 m. is placed at the central façade.
Its collective tank is covered by a lowered barrel vault, which is though hardly evident by the side facades. A small opening is found at the western flank.
Water was channeled into a basin (kurna), which is now hidden by the vegetation that covers the fountain’s base, as a small hole- spout was set over the basin.
