There are no historical accounts on the founding of the castle. Nor have any of the studies come up with an exact time of its construction. We know, however, that was repaired by the Venetians. However, one can observe that the components of the castle are reminiscent of those of the late Byzantine castle of Mouchli and the Frankish ones of Passava and Tis Orias (Estella). Because there are no mentions in the historical sources of nearby settlements which it would have protected, perhaps the castle was built to monitor a larger area. It is likely to have been the residence of a Frankish feudal lord, a seat of one of the 24 fiefdoms that make up the Barony of Akova. Situated in the area of the medieval Skorta, its role would have been to control these unruly residents and to curb their descents to the west, as far as Eleia, where lay the seat of the principality.
In 1320 the entire barony passed to the Byzantines, to Andronikos Palaeologus Asan; in whose hands it remained until 1460 when the Peloponnesus was conquered by the Ottomans, apart from a few castles. The Venetian lists referred to it as Argiro Castro vel Agnocastro (1463) and Arzirocastro (1467). In 1469 it is reported as damaged and in 1470 the Turks occupied it. In the 18th century, the castle is referred to either on maps or in the repairs carried out by the Venetians (1685-1715). The castle is mentioned in the title of the Archdiocese of Dimitsana and Argyrokastro during the Turkish occupation.
