Vouno lies above the bay of Agios Nikolaos and the settlement of Avlemonas and was historically a place of worship. There are two Byzantine churches here. The eastern one is dedicated to Saint George; it is a simple, single-room vaulted temple with a mosaic floor dating from the 7th century. The mosaic depicts a hunting scene, with meandering birds and bears in a Hellenistic style. According to tradition, the church was built by the Byzantine Empress Theodora. The western church is a single-room domed church of the Kythira type, dedicated to Panagia Myrtidiotissa and Saint Nicholas. The dome stands on a square building, and there are two niches on the eastern side. There are many churches on the island that have a similar architectural design, such as those 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.
