Liodora is part of the Municipal Unit of Iraia, which belongs to the Municipality of Gortynia. It is situated on a low hill near the left bank of the river Ladon, 5 km northeast of Tripotamia, 8 km west of Paloumpa and 17 km northwest of Dimitsana, the capital of the Municipality.
Liodora is situated in a hilly plateau and features several hills. The view to the south are blocked by a mountain slope. Kryonero has several valleys around the area, which also contains forests, grasslands, farmlands and bushes.
The name Liodora was probably derived from Heliodorus (Greek: Ηλιόδωρος) or Leodorus (Greek: Λεόδωρος), an ancient ruler or nobleman of the area, or it is a derivative of the word "Herodora" (Greek: Ηροδώρα), denoting Hera, the wife of Zeus, giving gifts. About 5 km to the south of the contemporary village was Ancient Irea, a city built next to the Alfeios River, close to Ancient Olympia. In the Middle Ages, the village was the capital of the entire region, which also bared its name.
The location of the lost ancient city of Melaneai (Greek: Μελανεαί) is believed to be in the vicinity of contemporary Liodora. Outside the village there is also an ancient cheese factory.
The permanent population of Liodora is currently around 50 people, a number which is more than doubled during holiday seasons. Following is the evolution of the official census figures on the village's population.
