This rickety wooden building, practically on the verge of collapse, is the largest wooden building in Europe and the second largest in the world. It stands on top of a small hill on Büyükada—a tiny island off the coast of Istanbul.
The Prinkipo Greek Orphanage, also known as the Rum Orphanage, was originally conceived to be a luxury hotel and a casino. But when it couldn’t obtain a permit, the building was turned into an orphanage. It operated for sixty years taking care of Greek Orthodox orphans. Once this establishment closed the building fell into neglect, and after half a century of being exposed to the elements, the 20,000-square meter structure is now in a state of heavy disrepair.
