A fortress located in the Sarıyer district of Istanbul, on a hill at the European side of the Bosphorous, it is an ideal place for imaginary quests, gothic photo sessions and some other sinister stuff. It was built in the middle of 15th century and who knows, maybe if you look around well enough there is quite a high possibility of finding an Ottoman or Byzantian ghost. Just be prepared to climb loads of stairs and don't talk too loud.
