It is situated west of Argos and tradition has it that it took its name after the daughter of Pelasgos, Larissa. It was constructed in the 6th century BC and it is there that the foundations of the temple of Athena Poliada and Zeus of Larisa were discovered. In the 10th century AD the Acropolis was replaced by a medieval castle (the Castle of Larissa), now dominating on the hill, which played a great part in the 1821 Greek War of Independence.
