The stone-built monumental bridge of Mavrozoumena was constructed on the road that connected Arcadia and eastern Messenia with ancient Messene. It stands ca. 5 km from the Arcadian gate, at the point where two rivers join into one, which southwards flows into the Pamisos River. It is a unique example of a three-way bridge, designed by pioneering ancient architects. It consists of nine arches and has three arms, joining in an inverted Y-shape at the confluence of the rivers. Each of the arms corresponds to one of the three roads that join here.

Its foundation and lower part are built with large rectangular blocks, much like the fortification walls of ancient Messene dating back to Hellenistic times. The surviving arched upper part shows more than one building phase, which includes large-scale repairs that could be dated over a wide period of time between the 12th and 15th centuries. According to tradition its construction is attributed to Mavrozoumena, the wife of a Mavrozomis, a lord of the region during the Middle Ages, hence the name ‘Mavrozoumaina Bridge’. It was repaired in the years of the First Ottoman occupation (15th-17th century), as evidenced by the surviving engraved inscription above the arch of the south-western arm.
