Isa Bey Mosque was built in 1375 near the ancient city of Ephesus in what is today Selcuk, Turkey. Parts of the mosque were built using stones and columns from the ruins of Ephesus and the Temple of Artemis. It was designed asymmetrically instead of a more traditional symmetric layout and includes a large courtyard. The mosque uses a Selcuk style of architecture rather than the Ottoman style that was used more often in later years.
Visitors can admire the facade on the western side which is covered in marble and carved with geometric designs and calligraphy inscriptions. You can all see the brick minaret that has survived over the centuries on the north side of the mosque and two domes in the center. The mosque sits below the citadel near the Basilica of St. John. From the mosque, you can look up at the impressive ruins of the citadel and the basilica. The view from the hill where the basilica sits gives an impressive perspective of the mosque as well.
Isa Bey Mosque is located on Atatürk Mh and is a 10-minute walk from the Selcuk main train station. Entrance is free. Certain areas are used for prayer, but there is also an area for visitors.
