Vouno is located above the bay of Agios Nikolaos and the settlement of Avlemonas and has been historically a place of worship. There are two Byzantine churches here. The eastern one is dedicated to Saint George; it is a simple, single-space vaulted temple with a 7th century mosaic floor. The mosaic depicts a hunting scene, with birds and bears Hellenistic meanders. According to tradition, the church was built by the Byzantine Empress Theodora.
The western church is a single-space domed church of Kythira-type, dedicated to Panagia Myrtidiotissa and Saint Nicholas. The dome is placed on a square building and there are two niches in the eastern side. There are many churches on the island that have a similar architectural design, like that of Agios Dimitrios in Kampianika of Alexandradon, Agios Nikitas in Kalamos, Agia Kyriaki in Mitata, Agios Nikon in Zagklanikianika, Agios Ioannis Theologos in Chamili (Kalamos) and two of the churches of the Pourko complex.
