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.

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.

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.

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.

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.

The "New Mosque" is not so new - it was built in the 1600s. Designed by Da'ud Aga, a pupil of Sinan, Yeni Camii has become a defining feature of Istanbul's skyline.

Commissioned by Justinian in the first year of his reign (527), this was an important stage in the development of Byzantine architecture. It is now a mosque known as the "Little Hagia Sophia."

The coastal town of Miletus was one of the most important cities in Greek Asia Minor until its harbors silted up. The famous architect Isidore was born in Miletus, and St. Paul stopped here on his Third Missionary Journey. There are many well-preserved ruins to be seen at the site, including an impressive theater, a Temple of Apollo, and two agoras.
