There is a top-secret military plant called "Hydropribor", located in South-East Crimea. This facility used to produce underwater weapons systems such as torpedoes, mines, etc. Only a very few knew about existence of this place, even in the neighboring city of Feodosia.
After break up of Soviet Union in the early 90's "Hydropribor" had stopped getting government procurement and had it closed, its classification had been removed.
Nowadays this facility is abandoned, it's territory totally neglected, but there are still a few buildings left. One of them was a hospital for plant's employes. This hospital is in the same condition now as it was more than 20 years ago.
Now this building boarded up, but if you get inside, you can see abandoned medical records, dentist tools and dentures, doctor’s offices and… outstanding Black Sea view out of window.
