The Isabey Mosque in Selçuk (near Ephesus) is a beautiful example of Seljuk Turkish architecture in an atmospheric location. It is the oldest known example of a Turkish mosque with a courtyard.
History

The Isabey Mosque was built in 1375 at the direction of the Emir of Aydin. Columns and stones from the ruins of the city of Ephesus and the Temple of Artemis were incorporated into the building. The mosque was restored in 1934.

What to See

The mosque is located just beneath the citadel in Selçuk near the Basilica of St. John. It measures 51m (153 feet) by 57m (171 feet) including a large courtyard.

The mosque itself consists of two lateral aisles covered with two domes in the center. The surviving brick minaret on the north side has an octagonal base. The west facade is covered in marble, carved with beautiful geometric designs and calligraphy inscriptions.
