Xinjiang Prison Camps

Because everything on Google is prohibited in China, we're kind of cheating on this one. China was not happy when Google moved their headquarters to Hong Kong. The only information that may be available on Google Maps in China is that which may have been preserved before 2010. However, China has not outlawed other mapping services, such as Baidu.

Similar to Google, this service creates maps using satellite pictures. However, some of those maps, like Google, have been hidden. Prison camps in Xinjiang, northwest China, appear to be one of the most prominently hidden places.

Uyghurs, Muslims, and other ethnic minorities are allegedly detained in these facilities. More than 400 facilities were found in the area after a thorough review of the maps. 315 of those are reportedly operating as prison camps or other similar facilities. To put it into context, it's thought that the Xinjiang prisons may have held anywhere about 1.5 million inmates.
