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.
One of the most sacred cities in the ancient Greek world, Didyma had an oracle of Apollo that rivaled Delphi. Today, its massive Temple of Apollo is still majestic in ruins.
Eyup Mosque and Mausoleum
This is the holiest site in Istanbul and one of the most sacred places in the Islamic world. Erected by Mehmet the Conqueror, it honors the tomb of Eyüp Sultan, the standard-bearer for the Prophet.
Commissioned by Sultan Suleiman the Magnificent and constructed by the great Ottoman architect Sinan, this beautiful mosque patterned after the Hagia Sophia was finished in 1557.
The "Basilica of Holy Peace" dates from the 6th century and was transformed into the arsenal of the Topkapi Palace in the 1460s. Today, its excellent acoustics make it a popular venue for concerts.
Church of the Holy Apostles
This great church was built by Constantine as the resting place of Byzantine emperors, several apostles, John Chrysostom and Gregory the Theologian. Destroyed in the Crusades, its materials were used to build the Fatih Mosque.
