The abandoned mine that will house the Lefdal Mine Datacenter was originally used for extracting olivine, a magnesium iron silicate. The facility is tunneled on six levels, featuring mountain halls with roof heights of up to 16 meters/52 feet, accessible via underground 'avenues' and 'streets' in a grid.

The maximum potential floor space is 120,000 square meters, or nearly 1.3 million square feet. The Statue of Liberty, Boeing 737, trailer and car on the lower right of the picture show the colossal scale of the facility.
