Tik-kuyu ("vertical well") - an ancient siege well of the cave city Chufut-Kale. It was discovered only in 1998-2001. The well was used to get water during the siege. The well supply went from a source which was outside the walled city. The underground gallery was called “Altyn-Merdven”, or “golden staircase”, which spoke of the value of water for the inhabitants of the fortress. A gallery with a length of more than 120 meters downward inclined leads to the well, at the end of it there are 30-meter spiral staircases. The vaults of the gallery sometimes adorn the stalactites of ancient origin. The walls of the underground structures are covered with inscriptions Karaite italic, Aramaic square italic, and Latin. The bottom of the structure is a spacious platform, on which there is an altar and two small pools-pools connected to each other. In the place where the gallery came to the surface, there was a tower.
