In 1905, archaeologists found artefacts here from the Neolithic period. Researchers from the University of Amsterdam in 1997 found clay seals and coins from the Early Helladic era. There is also evidence of a Mycenaean city about 1800 BC until when the Dorians arrived. Geraki (or Ancient Geronthres) has an acropolis that is guarded with a wall, even if there are archaeological finds dating from Neolithic times, i.e. from around 6000 B.C. In Christian times the area was built up with Byzantine churches decorated with frescoes and bas relief, as well as a Frankish castle built on a hill overlooking all of the plateau of Geraki.
