The building in the background is an early 20th century orphanage and the second largest wooden building in the world.
Unfortunately couldn't get a close view, the area is restricted because the building is at a high risk of collapsing.
The last picture shows the Greek İsa Rum monastery.
Pictures taken on the Turkish island of Büyükada.
