It is bounded by Arcadia to the west and southwest, Corinthia to the north, the Saronic Gulf, the Attica prefecture and the Troezen area to the east and southeast over water, and the Argolic Gulf to the south. (The Argolid of ancient times included Troezen.)
From 1833 to 1899, the prefecture was part Argolidocorinthia, which included Hydra, Spetses and Kythira. It joined Corinthia to form Argolidocorinthia again in 1909. Forty years later, in 1949, the prefecture was finally separated from Corinthia. See also Argolidocorinthia.
In early 1998, a flash flood carrying muddy water swept through the valley near Argos and devastated citrus crops and other area agriculture, including olives and other crops, and grazing areas. Damages were several million drachmas, then still the currency of Greece.
