The church of Agias Kiriakis is in the bay of Vlichos, opposite Nydri. You can visit the church by small rented boats. According to the inscription in the church: "The holy temple was erected in 1906 and is owned by Cacon". Just next to the building (on the left), at a height of about 3-4 meters, there is also a small cave where there are icons, as well as a staircase leading as there.
