Inside Margaritsano gorge we meet the Byzantine church of Agia Paraskevi, which can be accessed Pigouniana via a dirt track. This is a small single-nave barrel-vaulted temple with its interior adorned by frescoes of the Venetian era.
Most temples dedicated to Agia Paraskevi, which is the patroness of the eyes, should be built next to springs of clean water. Thus people who suffered with vision problems had to rinse their eyes with water from the spring next the church. Indeed, even in here, next to the church there is a spring and a few meters later we come across a ruined watermill.
