There are few historical references to Castle Kiveri. Pausanias (2nd century AD) reports that on the top of the Pontinos hill were the ruins of the Temple of Athena Saitis, and the foundations of the house of Ippomedon.
Many centuries later, during the period of Frankish rule, comes the first mention of the castle: Gautier de Brienne II, heir to the Duchy of Athens and Lord of Argos and Nauplia, mentions in his will in 1347 the castles of Kiveri (Chamires or Chameres) and of Thermisia (Tremis). It is there stated that the sixty hyperpyra (gold Byzantine coin, called the bezant in the West), the income from renting premises at Argos for the sale of fabrics, is to be given by the executors of the will to the castle priest, providing he stays there continuously and conducts a daily liturgy.
The successor to Gautier de Brienne was his nephew Guy d'Enghien. His daughter, Maria d'Enghien, Lady of the castles of Argos, Nauplia and Kiveri, sold her lands to Venice in 1388. But before the Governor (provveditore) Perazzo Malipiero could take over their administration, the Despot of Mystras, Theodore Palaeologos, captured Argos and Kiveri.
Kiveri castle did not survive the VenetianTurkish war of 14631479. In 1481 the Treaty between the Turks and the Venetians states that the latter could keep it, but could not rebuild it.
Around 1715 the settlement at the foot of the Pontinos hill was referred to as Tsiveri; today Myloi is there located.
Before 1841 the famous traveller and historian JeanAlexandre Buchon wrote that the central tower was preserved to a height of several storeys.
