It was a complex of buildings, built on the bases of an Enetic construction (1687-1715) in order to accommodate the Sisters’ of Mercy hospital. J. Kapodistrias constructed them to lodge cavalry’s barracks. During Turkish domination, it changed to an agora and lodged the Post Office. The government of 1824 voted the creation of University of Argos and purchase of a big building site, in which Kapodistrias built the cavalry’s barracks later on.
