The history of the two islands is evident in the archaelogical sites and the historical and religious monuments of the area…
Archaeological site of Vroukounta (north of Avlona): Vroukounta was one of the four ancient cities of the island. Currently only parts of the city’s wall, burial chambers, dug in the hellenistic rocks, three paleochristian churches and some tombs of the same period are salvaged.
Saria, Palatia bay: Scattered in the area are numerous pieces of pottery and a stone neolithic axe, copper age weapons and tools. Visitors may also see an ancient (probably hellenistic) carved tomb, a paleochristian settlement, including four basilicas and a bath, medieval
structures with unique domed roofs, that are related to the Arabic raids between the 7th and 10th centuries AD.
Saria, Kastelos: A hill close to the south of Palatia, where visitors can see an ancient (probably hellenistic) wallprotected acropolis, a carved burial chamber in the foots of the hill, and a paleochristian basilica in its peak.
Saria, Argos: Abandoned traditional settlement.
Kimisi Theotokou church (Olympos): The central cathedral of the village. The inner walls are covered by fresco paintings dated from the Ottoman period. It is worth mentioning the wooden carved temple made during the 17th century.
Other major churches and chapels: St. Zacharias (Saria), a small white chapel on the peak of the mountain, just after a path made of boulders. In Olympos there are also important
single spaced chapels, such as St. Anna the Catholic, decorated in an abstract manner, probably from the Byzantine period of iconoclasts (8th to 9th centuries AD), adjacent to the latter is
the chapel of St. Saranta, decorated with 11th century frescos. Lastly, abstract decorations were also used in the now ruined chapel of St. Onoufrios in the entrance of the village.
