Temple of Artemis
In ancient times it was one of the Seven Wonders of the Ancient World, but today the Temple of Artemis is represented by a single column standing in a swamp.
House of the Virgin
Discovered in a vision by a bedridden German nun in 1812, this stone building is believed by many Catholics and Muslims to be where the Virgin Mary lived her last years. There is also a healing fountain.
Cathedral of the Holy Cross
The Church of the Holy Cross on Akdamar Island is a ruined Armenian cathedral dating from 921 AD. Beautifully situated on Lake Van, the church is famed for its fascinating medieval sculptures.
This Roman market town was an early center of Christianity and one of the Seven Churches of Revelation. In the 4th century, Apollinaris of Laodicea taught the heresy of Apollinarianism.
Kariye Camii (St. Savior in Chora)
This 11th-century church (later a mosque and now a museum) contains one of the finest preserved galleries of Byzantine mosaics anywhere.
St. Polycarp Church
Although reconstructed in 1620, this church is the oldest in Izmir. It honors St. Polycarp, who was bishop of Smyrna and was martyred on a nearby hill in 155 AD.
Göreme Cave Churches
Cappadocia's most famous attraction, for good reason, is the Göreme Open Air Museum, a complex of medieval cave churches carved out and painted by Orthodox monks.
Cave Church of St. Peter
This ancient cave church is believed to have been dug by St. Peter himself. Fronted by a Crusader-era facade, it still hosts worship services and attracts pilgrims.
