There are cloud storage mega-centers all over Silicon Valley that take care of our smartphone camera rolls and contacts lists. There are the NSA's data centers, which do similar things but the permissions are (at least in theory) different.

In his series Deposit, Swiss photographer Yann Mingard reveals another type of data storage facility: the privately owned bunker space within which individuals, companies and even nation-states secure their most precious code, papers, and in some cases, genetic material. These data centers aren't intended to intercept or analyze data; they're merely meant to protect the contents from virus, loss and—most of all—from snooping.

Mingard's exquisite darkened images of data centers from Switzerland, Sweden, and the United Kingdom form the fourth and final chapter of Deposit, a sprawling four-year project which meditates on the anxieties of contemporary life. Deposit delves deep into the real and perceived threats to human survival, and the emerging technologies that promise security.
