Didyma is a small town in the south of the prefecture of Argolis near Kranidi, built at the foot of the mountain Didyma. The cultivation of olives and the production of olive oil are important occupations for the locals. Livestock farming and the production of dairy products also employ many of the people of the area.
The origin of the name is explained in two ways, firstly that it originated from Mount Didymos or that it was adopted from the Didyma caves just outside the village. During the Greek Revolution the residents of didyma took part in the struggles for liberation.
Outside the village there are two large crater-shaped caves, the caves are impressive because of their size; the first one can be seen from a distance, the second cave is more impressive, as entering it through a small cavernous entrance we find a completely different vegetation compared to the surrounding area. Still inside the cave there are two small churches, St. George of the 13th century and the church of the Transfiguration (Metamorfosi), with a short walk you can see them up close.
