The Niva button factory in Patisia, Greece, opened in the 1940s and remained in operation for decades before being abandoned.
“The photo was available on various international websites. Most of them state that it is an abandoned button factory in China. […] With a little searching and a lot of luck, we found where the ghost factory really is! It is not in the Chinese city of Longhua Shenzhen, as mentioned in most posts, nor are we talking about a set photo. The abandoned button factory is located in Patisia!”
