Елисейна ЕАД - Eliseyna EAD - Abandoned Mine and Non-Ferrous Metallurgic Plant near Zverino (Bulgaria)
Someone who used to live in Zverino told me:
This factory was processing copper and many other black and colorful metals. After democracy came to Bulgaria, this factory (called "Eliseyna EAD") was gradually abandoned..
