Büyükada consists of two peaks. The one nearest to the iskele (ferry landing), İsa Tepesi (meaning Jesus Hill in Turkish), formerly Hristos (Χριστός, the Greek name for Jesus Christ), is topped by the former Greek Orphanage, a huge wooden building now in decay. In the valley between the two hills sit the church and monastery of Ayios Nikolaos and a former fairground called Luna Park.
The Aya Yorgi Church at the top of the hill is of particular importance for both Christians and Muslims. No one knows whether it is actually true or just a myth, but they say that if you unravel a roll of thread as you walk to the church on top of the hill, your wish will come true
