Monastery of Timios Prodromos

At the northeast side of Kastri you will find the canyon of Tanos river. The monastery of St. John the Baptist is built on a steep cliff, probably in the 12th century. Due to its inaccessible position, it was used during the war of 1821 as a base of operations against Ibrahim and as a shelter during the raids. The watermill that can be found there used to grind gunpowder at that time. Ibrahim and his troops sieged the monastery twice without success.
