Ayia Sofia is a settlement in the province of Kynouria in the prefecture of Arcadia.
It is located on the road that links Astros with Tripoli, 20 kilometers from the first.
It is a secondary castle-like settlement with settlers from Karatoula and originally served as a winter settlement.
Northwest of the settlement is the bridge of Armaka.
A traditional one-arched bridge supposedly built in the 1900s by Castrite masters and still standing as an authentic example of the folk architecture of the area.
