Prastos was a small town located in the region of Arcadia in the Peloponnese, Greece. The town was founded in the early 4th century BC by settlers from the island of Rhodes. Prastos became an important center for trade and commerce due to its location on the Via Egnatia, a major Roman road that ran through the area. The town flourished during the Roman period, but began to decline after the Empire fell in the 5th century AD. By the early 21st century, only a few hundred people remained in Prastos and most of its buildings were in ruins.
